Writing of writing questions about the paper test 1 "Software demand analysis method and tools"
Demand analysis is the most important type of ability that system analysts should have. In order to determine whether the paper is in good meaning, the solution focus on the "method of software demand analysis" and tools "is generally summarized; (1) The methods and tools selected in line with the basic goals and tasks of software requirements analysis. It is to help describe the functionality and performance of the developed software, reflecting the various restrictions received by the software, clarifying the interface specifications between the software and other system components, and can help define demand In the software requirements specification specification. (2) The methodology and model used in the need to distinguish and explicitly develop. That is, different development models should have a corresponding different demand analysis and definition methods and tools. (3) The specific method used in software demand analysis can be described in detail, and the main principles and strategies of these methods are discussed. (4) It is possible to discuss the specific auxiliary tools used in software demand analysis, and can be summarized and strategies considered when they are selected. (5) Analysis of the corresponding effects generated by the selected tools and methods require specific, true, and trusted. The tools and methods for selecting software demand analysis are relatively high levels of activities, and currently in further development, there should be appropriate discussion on future improvements. In summary, the current demand analysis has two major methods: object-oriented methods and structured methods, the former seems to be accounting. From the actual situation of the 2001 exam, there are many people who have a very good person, and the key is "according to the actual situation of the project and the actual needs, the correct corresponding method is applied." Any project's "demand analysis process" is nothing more than: identify practical application issues and application environments -> Analysis and synthesis -> Develop Demand Specifications -> Review Demand Analysis. As the main result of demand analysis is "Demand Specifications", which should be: function, performance, environment, user interface, security, reliability, resource usage, cost, progress, etc., and should list the system will The goal is achieved. The above two demand analysis methods have indeed completed these tasks. An important reason for encouraging more projects with object-oriented demand analysis methods is that demand analysis aids are maturing. The demand analysis tool mentioned in the 2001 examinations involves a wide range, such as UMI. Standard Rational Rose, Rational Requisite Pro, Microsoft provides auxiliary tools, Playcase, etc., and even auxiliary analysis tool within the software company's own self-developed. However, the tools of domesticization can be described as the angle of the phoenix, and the proportion is very low. UML (Unified Modeling Language) is becoming the preferred standard for object-oriented analysis. In order to help readers better read the following papers, this is a very simply introduced the demand analysis tool software for Rational's Analyst Studio, which is a relatively complete set of tools designed for application problem analysis and system definition. Suitable for team joint development. Analyst Studio includes the following. (1) Rational Requisite Pro: It is used to help developers create a type of demand management software that created and manages demand throughout the life cycle. (2) Rational Rose Data Modeler Edition; UML using industry standards helps developers exchange and communicate all kinds of demand in software overall structures in graphical ways, which is the Profit Rose Data. Rational Rose Data The core part of the Modeler Edition software has added Data Modeler to support database design.
