Data Requirements Specification
1. Introduction
1.1 Writing Purpose
Describe the purpose of writing this data requirement specification and point out the intended readers.
1.2 Background
A. Name of the software system to be developed;
B. List the task initiators, developers, and users of the project and the computing stations or computer network systems that will run the software.
1.3 Definition
Lists the definitions of specialized terms used in this document and the original phrases of the foreign acronyms.
1.4 references
List related references.
2. logical description of data
When describing data logically, data can be divided into dynamic data and static data.
2.1 static data
Lists All static data elements used for control or reference.
2.2 dynamic input data
Lists dynamic input data elements.
2.3 dynamic output data
Lists the dynamic output data elements.
2.4 internally generated data
Lists internal data generated for users or maintenance and debugging personnel in development units.
2.5 data conventions
Limits data requirements. The restrictions on data requirements for further expansion or use are listed one by one. The limitation on determining the critical nature in design and development should be clearly stated.
3. Data collection
3.1 requirements and scope
Describes the requirements and scope of data collection by logical grouping of data elements, specifies the data collection method, and shows whether the data collection is undertaken by users or developers.
3.2 input bearer
Specifies the predefined owner of data input. If the input data is related to an interface software, the source of the interface software should also be described.
3.3 Expected handling
Special provisions are put forward for the data collection and preprocessing process, including suitable data formats for applications, pre-defined data communication media, and input time requirements. For data volumes that require analog or digital conversion, information such as the conversion method and conversion factor should be provided for the software system to use the data.
3.4 Impact
Describe the potential impact of these data requirements on devices, software, users, and development units.
