Structured analysisIn software engineering, structured analysis (SA) and structured design (SD) are methods for analyzing business requirements and developing specifications for converting practices into computer programs, hardware configurations, and related manual procedures. Structured analysis and design techniques are fundamental tools of systems analysis.
Functional decompositionExpression of a function as the composition of two functions In engineering, functional decomposition is the process of resolving a functional relationship into its constituent parts in such a way that the original function can be reconstructed (i.e., recomposed) from those parts. This process of decomposition may be undertaken to gain insight into the identity of the constituent components, which may reflect individual physical processes of interest.
Abstraction (computer science)In software, an abstraction provides access while hiding details that otherwise might make access more challenging. It focuses attention on details of greater importance. Examples include the abstract data type which separates use from the representation of data and functions that form a call tree that is more general at the base and more specific towards the leaves.
Object-oriented programmingObject-oriented programming (OOP) is a programming paradigm based on objects – software entities that encapsulate data and function(s). An OOP computer program consists of objects that interact with one another. An OOP language is one that provides object-oriented programming features, but as the set of features that contribute to OOP is contested, classifying a language as OOP – and the degree to which it supports OOP – is debatable.

Originally, the central goal of the structured programming movement was to eliminate the need for and use of the goto statement.
Cohesion (computer science)In computer programming, cohesion refers to the degree to which the elements inside a module belong together. In one sense, it is a measure of the strength of relationship between the methods and data of a class and some unifying purpose or concept served by that class. In another sense, it is a measure of the strength of relationship between the class's methods and data.
Software engineeringSoftware engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintainingsoftware applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs. A software engineer applies a software development process to define, implement, test, manage, and maintain software systems.
Object compositionIn computer science, object composition and object aggregation are closely related ways to combine objects or data types into more complex ones. In conversation, the distinction between composition and aggregation is often ignored. Common kinds of compositions are objects used in object-oriented programming, tagged unions, sets, sequences, and various graph structures. Object compositions relate to, but are not the same as, data structures.Abstract data typeMathematical model for data types In computer science, an abstract data type (ADT) is a mathematical model for data types, defined by its behavior (semantics) from the point of view of a user of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations.
Coupling (computer programming)In software engineering, coupling is the degree of interdependence between software modules, a measure of how closely connected two routines or modules are, and the strength of the relationships between modules. Coupling is not binary but multi-dimensional. Coupling is usually contrasted with cohesion. Low coupling often correlates with high cohesion, and vice versa.
Source CodeSource Code is a 2011 science fictionaction thriller film directed by Duncan Jones and written by Ben Ripley. It stars Jake Gyllenhaal as a US Army officer who is sent into an eight-minute virtual re-creation of a real-life train explosion, and tasked with determining the identity of the terrorist who bombed it. Michelle Monaghan, Vera Farmiga, and Jeffrey Wright play supporting roles.*As an Amazon Associate I earn from qualifying purchases.
