The structured analysis technique uses function-based decomposition while modeling the problem. It focuses on the functions performed in the problem domain and the data consumed and produced by these functions.

Writing an efficient software code requires a thorough knowledge of programming. This knowledge can be implemented by following a coding style which comprises several guidelines that help in writing the software code efficiently and with minimum errors. These guidelines, known as coding guidelines, are used to implement individual programming language constructs, comments, formatting, and so on. These guidelines, if followed, help in preventing errors, controlling the complexity of the program, and increasing the readability and understandability of the program.

A process model can be defined as a strategy (also known as software engineering paradigm), comprising process, methods, and tools layers as well as the generalphases for developing the software. It provides a basisfor controlling various activities required to develop and maintain the software. Inaddition, it helps the software development team in facilitating and understandingthe activities involved in the project.

After the implementation phase, the testing phase begins. Testing of software is critical, since testing determines the correctness, completeness and quality of the software being developed. Its main objective is to detect errors in the software.

While selecting test cases the primary objectives is to ensure that if there is an error or fault in the program, it is exercised by one of the test cases. An ideal test case set is one that succeeds (meaning that its execution reveals no errors) only if there are no errors in the program.

Once the software is developed it should be tested in a proper manner before the system is delivered to the user. For this, two techniques that provide systematic guidance for designing tests are used. These techniques are discussed here.

Programming refers to the method of creating a sequence of instructions to enable the computer to perform a task. It is done by developing logic and then writing instructions in a programming language. A program can be written using various programming practices available. A programming practice refers to the way of writing a program and is used along with coding style guidelines. Some of the commonly used programming practices include top-down programming, bottom-up programming, structured programming, and information hiding.

The test plan focuses on how the testing for the project will proceed, which units will be tested and what approaches (and tools) are to be used during the various stages of testing. However it does not deals with details of testing a unit nor does it specify which test case are to be used.

When tasks are defined and schedules are estimated, the planning effort has sufficient information to begin staffing plans and organizing a team into units to address the development problem. The comprehensive staffing plan identifies the required skills and schedules the right people to be brought onto the project at appropriate times and released from the project when their tasks are complete.

Data design is the first design activity, which results in less complex, modular and efficient program structure. The information domain model developed during analysis phase is transformed into data structures needed for implementing the software. The data objects, attributes, and relationships depicted in entity relationship diagrams and the information stored in data dictionary provide a base for data design activity. During the data design process, data types are specified along with the integrity rules required for the data. For specifying and designing efficient data structures, some principles should be followed. These principles are listed below.
