Sullivan [11] suggested that such an analysis can provide insights concerning modularity, phased project structures, delaying of decisions and consistency are Reusability: Is it possible to avoid code duplication? Modularity is a direct consequence of the subdivision of a system into its building blocks. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. References i. IEEE std 830-1998, IEEE recommended practice for software requirements specifications. Taught By. This builds the teamwork spirit that is required to complete a major project that requires thousands of lines of codes. Modularity is an integrating element directed at highly customizable manufacturing engineering structures. Withey, J., "Investment Analysis of Software Assets for Product Lines," Software Engineering Institute, Carnegie Mellon University, Technical Report CMU/SEI-96-TR-10, 1996. Software architecture refers to “the overall structure of the software and the ways in which that structure provides conceptual integrity for a system” [Sha95a] Architecture is the structure or organization of program components (modules), the manner in which these components interact, and the structure of data that are used by the components. the ‘solution’), or of the target fitness specification (i.e. I don't know if this is what Booch means.

A faulty function can easily be checked for errors when in a module. Abstraction: The ability to represent parts of a program with a summary of their essential characteristics 2. Each module is a well-defined system that can be used … Modularity helps to have extensible, modifiable, portable, maintainable, reusable, understandable and flexible software. Just like we expect car to work all the time and can't afford to break or reboot unexpectedly, software industry needs to continue to learn better way to build software if it were to become integral part of human life. Their specific functions divide these modules. In such cases, modularity is a key weapon that helps in reducing the complexity of such software or projects. In the design phase, many critical and strategic decisions are made to achieve the desired functionality and quality of the system. Software is more than just a program code. Coupling. Software design is a phase in software engineering, in which a blueprint is developed to serve as a base for constructing the software system. https://www.youtube.com/watch?v=DuFPj8MlAVo. To define a modular system, several properties or criteria are there under which we can evaluate a design method while considering its abilities. Since the modules are independent, the complete software is a collection of functional units or sub-programs to make the complete program. A module is an individual component which can be utilised with a number of functions and applications in combination with other components in … Google Scholar; Index Terms. Modular programming is closely related to structured programming and object-oriented programming, all having the same goal of facilitating construction of large software programs and systems by decomposition into smaller pieces, and all originating around the 1960s. These activities may involve the development of the software from the scratch, or, modifying an existing system. The Advantages of Modular Software and Programming Modular Programming is a process that involves splitting a computer program into individual sub-programs. the ‘problem’). Director of Graduate Studies, Software Engineering. Module strength Fig. Some of the modules … Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below. Narek Narek. It is not clear whether modularity, regularity and hierarchy are properties of the system being evolved (i.e. Language features. Modularity in programming simply encourages the separation of the functionality in a program into distinct and independent units such that every unit has everything required for it to execute just that aspect of the program. This makes the programmer better organized in his coding which helps when referencing. A software system cannot be made modular by simply chopping it into a set of modules. In such projects that involves tens of thousands of lines of code, having a clear knowledge of what a segment of code does becomes more difficult. It allows new features to be seamlessly added when desired, and unwanted features to be removed, thus simplifying the user-facing view of the software. System integration focuses on the interfaces between system elements. Modularity helps t… Narek. Reliability: a program satisfies its intended functions. Having each task in its discrete module makes the process a lot easier to carry out. Software Design: Cohesion 4:26. A large and growing fraction of software engineering is now carried out in object-oriented languages, taking over the domain traditionally covered by procedural languages. Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready. Data Flow Diagram (DFD) is a graphical representation of data flow in any system.

It is the only property that allows a program to be intellectually manageable. In industrial design, modularity refers to an engineering technique that builds larger systems by combining smaller subsystems. Modular software design is done by breaking the larger code into smaller sections, think modules, that hold specific functions. A module having low coupling and high cohesion is said to be functionally independent of other modules.. In fact, it can be claimed that it is the most important phase of the whole process. Module might be an overloaded term, so much that Wikipedia describes it under the term Modular Programming when discussing its use relative to software. Modularity is where abstraction and partitioning come together. As much as I understand here modules are like Java packages. Creating units or classes ensures this. Software Design: Coupling 4:09. Low coupling often correlates with high cohesion, and vice versa. Furthermore, code changes may lead to inconsistencies between the implementation and other design artifacts. Communication: Whether reporting progress to a supervisor, explaining a product to a client, or coordinating with team members to work on the same product, software engineers must be adept at communicating via email, phone, and in-person meetings.
