Computer software includes the source code for the get system and all the supporting documents generated during analysis, design, implementation, testing, and maintenance of the system. Internal documentation includes standard prologues for compilation units and subprograms, this document is for software source code, and the internal comments embedded in source code.
Program unit notebooks provide mechanisms for organizing their work activities and documentation efforts of the individual programmers. This article describes some aspects of supporting documents, the use of program unique notebooks, and guidelines for internal documentation of source code.
Writing a good design document
The first you to be explicit and consider the important issues before starting implementation. They allow a group of people to review the design and therefore to improve it.
Requirement specifications, design documents, test plans, user manuals, installation instructions, and maintenance reports are examples of supporting documents. These documents are the products that result from systematic development and the maintenance of computer software. Tools, techniques, and notations for generating and maintaining these documents are discussed.
A systematic approach to software development using that supporting documents evolve in an orderly manner and that the documents are available when needed. In the ad hoc approach to software development, preparation of supporting documents is usually a defect and its implementation is completed.
Those documents should be evolved as a natural by-product of the development process. Customer needs and constraints are recorded in the requirement specification, the requirements provide the Framework for architectural design, detailed designer evolves from architectural design, source code is developed from the architectural and detailed design. Test plans, user manuals, training programs, installation instructions, and maintenance procedures evolve throughout the development cycle. The quality, quantity, timelines, and utility of the supporting documents are primary messages of the health and well-being of a software project.
Program unit notebooks
A program unit is a unit of source code that is developed and maintained by one person, the person is responsible for the unit. In a well-designed system, a program unit is a Subprogram or group of subprograms that provide a well-designed function or form a well-defined subsystem. A program is also small enough, and modular enough, that it can be Aravali tested in isolation by the programmer who develops the modifies it. Program unit books are used by individual programmers to organize their work activities. And to maintain documentation for their program units.
A program unit notebook consists of a cover sheet and several sections. The cover sheet is the table of contents and the sign off sheet for the various milestones associated with the program unit.
The section in a program unit notebook responds to the various faces of the unit life cycle. The cover sheet used to record protected under actual milestone dates, and the sign off by a reviewer indicates satisfactory completion of the life cycle phase. Reviewers are usually team leaders or product managers who have responsibility for that Total system or a significant subsystem.
The requirement section of a program unit notebook contains only the specifications but is related to that particular program unit. Both the initial version, as agreed to by the customer, and copies of subsequent modifications to the requirements are maintained in the notebook. The architectural and detailed design section of The Notebook contains working papers and the final design specification. Working papers should be organized to indicate why various alternatives were chosen and others rejected.
This information can be valuable to get subsequent modifications. The unit test plan contains a description of the approach to be used in the unit, testing, the testing configuration, the actual test cases, the expected outcomes for each test case, and the unit testing completion criteria. The unit test plan evolves in conjunction with the design and implementation of the unit. The section containing unit source code contains a listing of the current version of the unit and listings of significant previous versions.
It is not expected that all syntactic Android debugging runs will be retained, but a listing of earlier versions that existed before significant modifications should be retained, particularly the maintenance phase of the life cycle. The test results section contains results from the test runs and an analysis of those results in terms of expected results. Again, not all debugging runs will be retained, but significant test runs should be retained.
The problem report may describe an error situation And desired modification. A copy of each problem report and its this position should be written in the program unit Notebooks of the affected program units. In some cases, this view of the problem reports will reveal the problems in certain units or collection of units. It is sometimes advisable to rewrite troublesome units that other than to continue repairing them.
