Tasks in Software Development

In looking at the soft test questions, it is found that there are many definitions of tasks in various stages of software development.

When the structured development method is used for software development, the interface design in the design phase is mainly based on the data flow diagram in the requirements analysis stage. the main task of the interface design is to describe the interaction between the software and the external environment. the calling relationship between modules in the software. The task of architecture definition is to define the main structural elements of software and the relationship between them. The task of data storage design is to determine the structure of the file system designed by the software and the table structure of the database, and the detailed design task is to determine the internal algorithm and data structure of each module.
