It is a process to achieve system specification by thoroughly analyzing, understanding the existing system. This process can be seen as reverse SDLC model, i. An existing system is previously implemented design, about which we know nothing.

Designers then do reverse engineering by looking at the code and try to get the design. With design in hand, they try to conclude the specifications. Thus, going in reverse from code to system specification.

It is a process to re-structure and re-construct the existing software. It is all about re-arranging the source code, either in same programming language or from one programming language to a different one.

Restructuring can have either source code-restructuring and data-restructuring or both. Re-structuring does not impact the functionality of the software but enhance reliability and maintainability. Program components, which cause errors very frequently can be changed, or updated with re-structuring.

Forward engineering is a process of obtaining desired software from the specifications in hand which were brought down by means of reverse engineering. It assumes that there was some software engineering already done in the past. Forward engineering is same as software engineering process with only one difference — it is carried out always after reverse engineering. A component is a part of software program code, which executes an independent task in the system.

It can be a small module or sub-system itself. The login procedures used on the web can be considered as components, printing system in software can be seen as a component of the software. Components have high cohesion of functionality and lower rate of coupling, i.

In OOP, the objects are designed are very specific to their concern and have fewer chances to be used in some other software.

In modular programming, the modules are coded to perform specific tasks which can be used across number of other software programs.

Software components provide interfaces, which can be used to establish communication among different components. Two kinds of method can be adopted: either by keeping requirements same and adjusting components or by keeping components same and modifying requirements.

Requirement Specification - The functional and non-functional requirements are specified, which a software product must comply to, with the help of existing system, user input or both. Design - This is also a standard SDLC process step, where requirements are defined in terms of software parlance. Basic architecture of system as a whole and its sub-systems are created. Specify Components - By studying the software design, the designers segregate the entire system into smaller components or sub-systems.

One complete software design turns into a collection of a huge set of components working together.
