What’s a programming domain?

[ad_1]

“Programming domain” in computer science and computer programming is a general term referring to the field or problem in which a program, programming language, or language syntax is designed to operate or solve. The term is most often used when referring to domain-specific programming languages, which are programming languages ​​designed to specifically address the needs of a single field or problem. There is no real formal specification for what is or is not a programming domain, although there are some commonly used broad categories, such as business, Internet and networking, and some more specific domains, such as optical recognition or messaging. The term is quite abstract, so it is often applied during academic research or during the design phase of software development.

One purpose of defining a programming domain can be to help model a domain-specific programming language. This means that if a programming domain is defined as Internet email, the programming language will be designed during the initial design phase specifically to address Internet email-only problems, usually at a very high level for the end programmer. . In this example, a domain-specific programming language for the Internet mail programming domain might include commands such as “send_to_address” or “check_valid_address” which are used to troubleshoot specific network problems associated with Internet email but serve no purpose beyond broad and general beyond that .

In a broader sense, a programming domain can also be an important concept when using domain-based design. This type of software design pattern meshes the programming language and the entire application infrastructure and control logic around the domain. By linking the programming domain to different levels and stages of development, context emerges for certain parts of the application and, in very complex programs, can make it easier for programmers and engineers to troubleshoot and visualize the internal workings of the program.

One complication one may encounter in the broader software development industry is that, while many development teams might use a programming domain and domain-related models, there is no standardization on what a domain actually entails, what it is called, or what it is called. it should be displayed. What one company might call a corporate domain might be called a corporate domain by another company. When applications, models, and frameworks are developed for a specific domain by one company, they can be published, advertised, or sold as development tools or solutions for another company that may be working within the same domain. Without a standard for domain naming, solutions based on existing domains could go completely unnoticed.
