2 overall design
2.1 demand regulations
Note The functional performance requirements of the main input and output projects of the system, detailed description can be found in Appendix C.
2.2 Operation Environment
Briefly illustrate the provisions of the operating environment (including hardware environment and support environments) of the system, detailed description, see Appendix C.
2.3 Basic design concepts and process flows
Describe the basic design concepts and process flows of the system, try to use the form of the chart.
2.4 structure
In the form of a list and block diagram, the division of the system element (each layer module, subroutine, utility, etc.) of the system is to indicate the identifier and function of each system element, and the control between each element is given. And controlled relationship.
2.5 Relationship between functional and program
This article uses a matrix diagram to illustrate the allocation relationship between various functional requirements:
2.6 manual processing process
The artificial processing process (if any) has to be included during the operation of the software system.
2.7 I have not yet been issued
Note The designers believe that the designers believe that the designers must solve before the system is completed.
3 interface design
3.1 User Interface
The commands will be provided to the user and their syntax structure, and the answer information of the software.
3.2 External interface
Note The arrangements of all interfaces of this system include interfaces between software and hardware, and the interface relationship between the system and the support software.
3.3 Internal interface
Describe the arrangement between the interfaces between the various system elements within the system.
4 operation design
4.1 Operation module combination
Note The combination of various operating modules caused by the system is applied to different external operations, indicating that the internal modules and support software over each run.
4.2 Running Control
Description Method and operation steps of each of the external operational controls.
4.3 Running time
Note Each run module combination will occupy the time of various resources.
5 system data structure design
5.1 Type of logical structure design
Given the name, identifier of each data structure used in this system, each data item, the logo, the record, the text, and the level of the identification, definition, length, and the interaction between the levels between them. .
5.2 Points of physical structure design
A physical relationship (index, device, storage area), design considerations, design considerations, design considerations, design considerations, design considerations (indexes, devices, storage areas), design considerations (indexes, devices, storage areas), design considerations (indexes, devices, storage areas), design considerations (indexes, devices, storage areas), design considerations (indexes, devices, storage areas), design considerations (indexes, devices, storage areas), design considerations.
5.3 Relationship between data structure and procedures
Describe the form of each data structure and access to these data structures:
6 system error handling design
6.1 error message
The form, meaning and processing method of the system output information when each possible error or fault occurs is said to be in a list.
6.2 Remedy
Note Workarounds that may be taken after the failure, including:
a. Backup Technique Description Preparation Techniques Adopted, when the original system data is lost, the established and started technique, for example, periodically record the disk information to the tape is a backup technology for disk media; b. Defining Technical Description Preparation Techniques Adopted, use another system or method of another efficiency to obtain certain parts of the desired result, such as an automatic system's efficiency technology can be manual records of manual operation and data;
C. Recovery and Reacture Technical Description The recovery restart technology will be used to restore the software from the fault point to the method of re-running the software from the beginning.
6.3 System maintenance design
Description For the convenience of system maintenance, the arrangements made in the program internal design include specifically arranged inspection and maintenance of the system in the program.
