I. Object-oriented visual modeling tool - rose 1.1 Why choose ROSE? During the development of the software system, developers often encounter the following questions: · You cannot understand the needs of users; · The system is difficult to integrate; · Software is difficult to maintain and expand; · For continuous changes; · Some serious Errors to find out after the project; in fact, the above problems can be summed up as a problem, that is, information exchange issues: there is no sufficient, effective exchange between developers and users and the interior of the developers. The fundamental is that the reason is that the system model does not explicitly explicitly in a unified manner. Unity can guarantee mutual understanding. Rational has been committed to modeling the standardization of modeling language for many years. He successively plays a unified modeling language UML under the flag-oriented master-oriented master-oriented master. (Unified Modelling Language) and continuously modify UML according to the feedback of industry partners (such as Microsoft, Oracle, IBM, HP, etc.) to ensure that it can adapt to the needs of different fields. Meihua is incense, and many years of efforts have finally achieved fruitful results. In November 1997, UML1.1 was identified as an international standard by OMG. Rational Rose is the industry-leading UML-based visual modeling tool. According to International Data Corporation (IDC), the research report of OOAMDC (object-oriented analysis, modeling, design and construction) tool market announced in May 1998, Rational Rose has been in the leading position in the market for the third consecutive year. It has reached 6,300,000 US dollars, and the market share has reached 26.4%, which has exceeded the sum of the three product market share. Roselink Partner Program is seamlessly integrated with Roselink Partner Program to seamlessly integrate Independent Software Merchants (ISV) and third-party developers to form a complete solution. So far, more than 150 well-known companies have joined the Roselink program, strive to create interfaces with ROSE to extract information from the model. Rational Rose can be used in combination with any object-oriented application structure, through the Rational Rose series, you can get direct support for all primary programming languages and fast application development tools: a. Model and code's high Rose can truly realize To, reverse and bidirectional projects. ROSE in the forward engineering can generate the corresponding code for the model, and Rose can export the model from the user's original software system, and Rose, Rose, which can truly realize the circular project between the model and the code in the two-way engineering. This ensures that the model is consistent with the code, and the user will not lose or override any code that the user has been developed in the bidirectional engineering. b. Multi-language support ROSE itself supported languages include: C , Visual C , Java, SmallTalk, ADA, and 4GL language: Visual Basic, PowerBuilder, and Forte, you can also generate interface definition language IDLs for CORBA applications and to database applications Generate a database description language DDL. Rose can provide support for CORBA 2.2. At the same time, ROSE also has more than 150 Rose-Link software vendors to provide support for other languages and fields for ROSE.
This also reflects the wide application of Rose in the OOA & OOD field from one side. To maximize the Rose users, Rose divide the product into Enterprise Edition and Expert Edition, and users can choose different versions according to their needs in developing language. c. Support for team development with strong support Rose supports team development: one is a team development method using SCM (software configuration management); the other is a team development method without SCM. These two ways provide users with great flexibility, and users can choose their team development based on the development of scale and developers and funds. In general, we recommend that users use SCM's team development, which enables us to develop a model development with a good support for large-scale parallel team development; while also facilitating model versions of the model, for future models Reuse laying a solid foundation. When Rose is developed with ROSE, ROSE not only supports SCM tools, but also uses the entire model, but the user can shoot the package in the model into a control unit, and use the SCM tool to manage these control units, and each control unit itself can be Dispatched different developers or specific developers for parallel development. Rose integrates internal integration with ClearCase and SourceSafe (Microsoft products), and as long as it is complied with Microsoft version control system, any version control system of the Microsoft version control system can be integrated into ROSE as configuration management. tool. In summary, Rational Rose can: • Support model team parallel development, model can be decomposed into a control unit in Rose to perform corresponding version control. • Support for motion or replication of model files or control units through virtual path mapping mechanisms. · Support team management of multiple different projects by integrating with standard version control systems. · Provide a Visual Differencing tool to support the merge function and report the difference between the control unit. · With Microsoft Repository has a good integration, support the ROSE model to Microsoft Repository to make it easy for another modeling tool to input this model, thereby increasing the reusability of the model. · Since the functionality of Framework can be increased in Rational Rose, the team can reuse numerous design models developed in early modeling work. d. Support Modeling Language UML Rational 麾 Has a three-oriented object: Grady Booch, James Rumbaugh, Ivar Jacobson, the UML (Unified Modeling Language), which is jointly created, is unified, and the object-oriented modeling method is eliminated. Differences in the mold. In November 1997, UML was approved by the US OO Industry Object Management Group (OMG) as an industrial standard language-oriented industry standard language, and has received support and certification of large manufacturers such as Microsoft, Oracle, IBM, HP. Microsoft's repository uses UML as a component description language. As an object-oriented industry standard language, UML is the only standard language that can be shared on UNIX and NT. e. INTERNET release ROSE's Internet Web Publisher's HTML version of the Web-based ROSE model enables other people to view the model through standard browsers such as Netscape Navigator or IE. f. Use a simple and custom-made document to generate ROSE itself provides a convenient function of directly generating model documents, but if you can use the Rational Document Generation Tool SODA to automatically generate OOA and OOD phases required Various important documents.
It is worth noting whether it is the document generated by Rose himself or SODA, and SODA can be launched directly in Rose, and Soda and MS Word are completely seamlessly integrated. g. Database Applications The solution uses ROSE to model the database, and Rose can automatically generate data description language DDL for ANSI, ORACLE, SQL Server, Sybase, Watcom, etc. Rose can also be tight between Rose and Erwin, and the other model can be derived from each other. In addition, ROSE can also achieve the forward and reverse engineering of Oracle 8, so that the user can: • Generate an object model from the relationship between Oracle 8, and further expand the object model to use Oracle 8's object capabilities · Visualized existing Relationship Database · Confirmation of the Discovery and Synthesis of Business Objects · Protection in an existing database area investment, while enjoying object modeling and development to all benefits to applications. 1.2 Configuration Scenario uses ROSE to perform visual modeling, running through software development, from the initial starting demand analysis modeling, detailed process, and to the final test and finally complete the entire project. This program is aimed at 25 people, and the development platform focuses on development teams on UNIX. Because such a team is a parallel development of several projects, it is recommended to use SCM (Software Configuration Management) team development, combined with Rational's software configuration management tool ClearCase, can arrange different developers for different projects, And specify the project that the group's developer can operate, which can meet the relative independence between the project group, and can set access to each other when necessary. The above situation, recommended configuration scenario: Rational Rose 98i for UNIX, FLOATING LICENSE: 4 - 6 Sometimes more members in the project group can use ROSE more easily, consider adding 2-3 license.

The distributed operation allows the CLIENT / SERVER-based computing structure to span online clients and servers, and ClearCase's advanced features directly solve the difficult problems faced by the original development team. The problems faced by software development include: the development and maintenance of current products, guarantee the precise product version, reconstructing the previously released products, strengthening the unity of development policies and the treatment of special versions. By solving these problems, ClearCase uses resource reuse methods to help the development team make all of them build more reliable.
A. ClearCase's four-functional company's ClearCase is a powerful software development configuration management tool. It is the guide for software configuration. It is based primarily based on Windows and UNIX development environments, which are applied to complex product development, distributed team development. , Parallel development and maintenance tasks, including support today's popular software development environment Client / Server network structure. In a fierce market competition, ClearCase features a direct response to the demand of the software team, such as software production, release, maintenance, etc. ClearCase is different from other software configuration management systems. From essentially, ClearCase is unparalleled because it contains a complete software configuration management tool and the structure is transparent, and the interface can be pro. Although ClearCase is an integrated environment, it is actually possible to divide all of ClearCase's characteristics into four specific features: version control Version Control · Workspace Management Workspace Management · Establish Management Build Management · Process Control Process Control Using ClearCase, you can maintain a well-known development environment to ensure smooth development work, and no software developers change their existing environment, tools and work. b. Graphical User Interface ClearCase Contains Traditional command line interfaces and Motif and Windows Click graphical user interface (GuIS) including tasks Setting the GUI component. The ClearCase of UNIX and Windows NT provides a drop-down and pop-up menu, a toolbar, and a Context-Sensitive help display to simplify the public user-level command. In addition, interfaces contain file browsers, views, VOBs, version trees, super join, optional data, and more in queries and selections that can simplify public data objects in ClearCase. GUI also provides intuitive comparisons and merged functions, describing insert, delete, and modifications with high brightness colors. GUI can be customized by extended scripting languages, enabled users to create their own buttons, toolbars, and multi-level menus. Customized organizational policies and scripts can be accessed in GUI, and external commands can also be integrated with GUI. In addition, ClearCase has a function of graphical events and attributes. The event display provides a history of related ClearCase control elements, which can be customized to the history of all elements.

Clearcase Attache also needs to run ClearCase R.2.1 or higher on UNIX Workstation (Dec, HP, IBM, SGI, Sun); ClearCase R.2.0 running on Windows NT PC. ClearGuide ClearGuide is a new software process management (SPM) product, which combines project management, workflow, and key features of process modules. ClearGuide exceeds the ability of traditional engineering changing management systems (including: project plan, definition, and process execution and management of all tasks for software lifecycles). With ClearGuide, the software development team can benefit from powerful timelines, predictable software projects and definition capabilities. Repeat and improve their software development process through a flexible process framework. They can also improve the accuracy and efficiency of the software development life cycle through regular task automation. ClearGuide requires a ClearCase3.x version. 4.2 Internal Network Management of Configuration Scheme Specification is a prerequisite for ClearCase, whether it is Windows or UNIX platform, ClearCase uses the system's user information to identify, verify, and record, for this purpose, using Windows 95/98 / NT Workstation users You must log in to the NT domain, each user on UNIX must have its own username and password. Since the user's actual network environment is different, ClearCase is configured with great flexibility. According to the user's specific needs, it determines the storage location of the VOB library, the assignment of Register Server, License Server, but there is a basic principle, ie Clearcase. The configuration is divided according to the concept of this concept, determines the permissions according to the user group. At present, most users are divided into project groups when doing software development, so that ClearCase is configured to have a certain law.
If the user's development environment is a pure UNIX environment, developers use UNIX, X terminals, X Server on the PC, divided into several project groups according to the situation of the project, and each group is generally a Unix host, in which case we You can set a VOB library for each project group. All project groups are stored in this VOB library, setting a total VOB library throughout the development team, store some public files and various project group development Stage sex, you can back up some important files, which can be used as an integrated platform for the entire project. This structure is a bit similar to triple structure, distributed, concentrated, flexible, and basically adapt to user requirements. If you need to consider the use of Windows / UNIX hybrid environments, you have to talk to each other between Windows and UNIX. CLEARCASE can only be used by Windows union access Unix, and you need to install NFS Client products when you do dynamic view access. For example, Hummingbird's NFS Maestro, NetManage's UNIXLINK97, Intergraph's DiskAccess, etc. When you configure ClearCase, you should take into account this, the top level VOB Server can only be UNIX. ClearCase is a true CLIENT / Server-based configuration management tool that implements the configuration management method to everyone. Therefore, there is only a few people in the development team to use ClearCase meaningless, our suggestion is every participation The personnel have a ClearCase license, and if the fund is can't be done, the License number should reach 60-80% of the total number of people. ClearCase components, users can determine the options and quantities required according to the actual situation.

Purify software quality is the life of the software! Software test should occupy 30% to 50% of software development fees, fully test quality. However, many software did not test before distribution. This Contradictory derived from two reasons: first, test software is extremely difficult, And with the complexity of software design, software testing is more difficult. Second, the implementation of the typical software test does not have a clear method and the required automatic support. When the complexity of the software makes the handmade fully testing no longer possibly, the automatic testing tool will be born, and the software is greatly improved. The productivity and efficiency of the test. For current complex software development projects, Run-Time errors, and access memory errors belong to the most difficult solution. Being out of the read and write operations of the array boundary, the memory is not preused to use uninitialized memory, which is likely to spend a few weeks to be discovered and correct.
PURIFY provides a graphical user interface (GUI) to solve these complex problems by checking Run-Time errors. • Identify error and memory loss in any application in any application. · Make developers to exclude Run-Time errors before bringing application to end users. · Easy to use, easy-to-understand user interface helps improve working efficiency and reduce training time. a. Widely capture run error In order to perform extensive examination, Purify uses Object Code Insert to cut memory access, which is done in the target code before the storage operation is inserted. The most prominent advantage of OCI is fullness: all code (including shared third-party function libraries) can be tested, even if hand-optimized integrated code is no exception. Compared to other similar tools, Purify applies OCI technology to discover more types of errors in more areas of the application. This completeness means that errors in the application code can be found. b. It is easy to use by adding a word -purify in the application-Purify, Purify starts automatic detection. After this procedure is a standard executable program that can be born and run in debug state. c. New graphical user interface Purify provides interactive mode of operation, generating a group of error messages to facilitate analysis. An intuitive GUI allows users to easily browse the error message. Use the hierarchical directory structure to provide detailed information specifying errors so that users should pay attention to the most serious errors. Access the application resources or development processes (such as: run, make, debug) just click on the mouse. This quick access makes it easy to modify the application error. d. Complete solution Purify and Pure Coverage (Pure Software provided to improve code coverage domain) is completely integrated together. The developer can get the data in the code overlay in the identification and clearing the error in the application. The perfect combination of Purify and Pure Coverage provides an impeccable solution for units with high quality development. e. Features · Intuitive graphical user interface · Can be found in the passive program, and you can find anywhere's error. The error types that can be identified include: - Unin-initialized local variables - unpredict Memory - Using the released memory - write operation in array boundaries - Readout of Array Boundary - Memory Loss Problem - Document Description - Stack Overflow Error - Stack Structure Boundary Error · Detailed Report, including stack tracking and source code lines • Identify and report errors in multi-clue applications · Immediately locate · Support for customized memory management · Support for other commonly used debugging tools, close to Pure Coverage Integration (except SGI) · Easy to install and master · Multi-platform F. benefiting · Comprehensively improve the application quality · Make changes to the current environment · Distribute more trusted code · Capture error as early as possible to make costs Utilization • Improve product performance · Cost for support and upgrading 2. Purecoverage Pure Coverage is the first tool for improving code coverage domains for developers. Patent Technology of Pure Software Oci (Object Code Insert) makes Pure Coverage stand out from the traditional code coverage domain tool. Pure Coverage effectively utilizes the code coverage domain by supporting the C and C development environments. · Preventing code from being distributed to customers without testing, improving software quality and quick and convenient identification of codes that have not been tested in applications • Improve all developers' development efficiency Pure coverage is easy to use. In fact, adding a word -Purecov before the Link line in Makefile, you can make developers to collect important overlay domain data from any application. Pure coverage can even collect information from the application that does not provide source. Using Pure Coverage does not need to be compiled again, developers only need to connect to Pure Coverage again.
Even if there is no debugging information, Pure Coverage can also collect important overlay domain data. a. Flexible report Pure Coverage reports overweight data with extremely flexible way. The hierarchical tree structure allows developers to browse critical overlay domain data at the level of applications, files, libraries, functions, rows, or basic blocks. By taking the mouse, developers can see the source program for comments, help analyze the test or unsatisfactory application code line. The powerful reporting function allows developers to merge data in multiple runs, and warn when the test data is below a certain threshold. b. Complete solutions Pure Coverage and Purify (Pure Software are used to prevent Run-Time errors) are perfect. Developers can collect code overlay domain data while identifying and eliminating errors. The combination of the two provides unparalleled solutions for the unit of high quality development. c.

Not only is the technology is new, but they are more difficult to test more than traditional software, because these software is more complex, and the user interface is more rich. The client / server (C / S) application constitutes an important type of software, and has become mainstream. They use more new technologies, in the C / S software architecture, the processing is dispersed on the client and server, where the client handles implementation and providing user interfaces and some local processing, while server processing Implement and provide specific services, such as database management or communications. Usually the client software has a GUI interface and can be operated on a relatively inexpensive PC; server software requires multi-user capabilities and higher performance. In this environment, the application of the application is facing new challenges. First, the software structure of GUI uses event-driven mode, which is very different from the traditional order program. The number of conditions combinations is large and variable. Traditional test methods are difficult to cover all operating states; in addition, due to force test demand Fast application development (RAD: RAPID Application Development) technology popularization and the difference in hardware and software configuration of multiple client sites, making automated tests an indispensable link.
From the server side, many clients have access to the test, which is difficult to simulate and reproduce with manual way. To this end, the quality of the customer / server application software based on the Window interface must rely on the automated test tool. Perhaps this is a view: Excellent test tool increases the budget for software development. But this is an old point of view. All software needs testing, and the test is the most important means of ensuring software quality. According to relevant expert studies, in the development cycle, the error will be checked for an error every step, and the cost will increase by 1/10. Therefore, the best start time for developers find errors is at the beginning of the project design, and then the synchronous test should be accompanied by every aspect of the development process, and truly develops and tests integrated. At the same time, for users who entrust others to develop applications, the software testing is also the necessary means of maintaining their own interests to ensure high quality applications. It can be seen that the users who are actually developing or the users who are entrusted to others have effectively needed to have excellent testing tools. From this point of view, excellent software testing tools will not only increase budget, but will reduce the cost of software development.

By displaying performance errors in graphics or text format, Quantify helps developers quickly analyze errors in the operating environment, help developers greatly improve the performance of the application, reveal the functions of the application, library, and operating system on application performance, reduce The possibility of performance bottlenecks during the development process. Quantify is easy to install, master. Providing developers with a simple way to avoid performance bottlenecks, and it has minimized the impact of the current development environment, just adding a word in makefile, greatly shortening the time used to find performance bottlenecks. Quantify's tree call relationship map provides visual data that reflects the key function. Function lists and detailed windows show a lot of data in the form of a table, easy to read. And you can read the source program of the gaze. Quantify accurately records the number of instructions executed by the source program. It subtracts the time consumption when reporting the CPU time, making the result correctly reflecting the time data.
Quantify transmits these records correctly between calling functions, so that the critical path is clear. Quantify users can control the type of data collected or reported: Filter a large amount of data; only the important program execution part is displayed. Quantify can operate in a way that interacts or batch. And regardless of the size of the application and the length of the test run time, Quantify provides information on performance information. Quantify can observe the implementation of sharing and third-party function libraries or UNIX operating system calls such as application performance. Developers can also identify performance issues in multi-clue applications. Quantify's add-on scripts track the performance improvement of the application by automatically comparing multiple runs, and combine data from multiple runs. Quantify is easy to integrate with conventional development modules for easy changes in application performance. Apply Quantify's data output function to strengthen automatic generation or user customization performance reports. · Provide extensive information, accurately display performance data, flexible, multi-change data control, extension, custom report · indicate user function, system call, sharing, and performance bottleneck in the third-party library · Collectable data, automatic Comparison of multi-operation • Provides multiple display methods for performance data · Provide user-defined, end-to-end data collection functions · Output function and add-on scripts make the performance monitoring and automation · can interact Working in two modes of batch and batch is greatly reduced.
