Front Controller
The front controller software design pattern is listed in several pattern catalogs and is related to the design of web applications. It is "a controller that handles all requests for a website," which is a useful structure for web application developers to achieve flexibility and reuse without code redundancy. Instruction Front controllers are often used in web applications to implement workflows. While not strictly required, it is much easier to control navigation across a set of related pages (for instance, multiple pages used in an online purchase) from a front controller than it is to assign individual pages responsibility for navigation. The front controller may be implemented as a Java object, or as a script in a scripting language such as PHP, Raku, Python or Ruby that is called for every request of a web session. This script would handle all tasks that are common to the application or the framework, such as session handling, caching and input filtering. Based on the sp ...

Software Design Pattern
In software engineering, a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. Rather, it is a description or template for how to solve a problem that can be used in many different situations. Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved. Patterns that imply mutable state may be unsuited for functional programming languages. Some patterns can be rendered unnecessary in languages that have built-in support for solving the problem they are trying to solve, and object-oriented patterns are not necessarily suitable for non-object-oriented langua ...

Mediator Pattern
In software engineering, the mediator pattern defines an object that encapsulates how a set of objects interact. This pattern is considered to be a behavioral pattern due to the way it can alter the program's running behavior. In object-oriented programming, programs often consist of many classes. Business logic and computation are distributed among these classes. However, as more classes are added to a program, especially during maintenance and/or refactoring, the problem of communication between these classes may become more complex. This makes the program harder to read and maintain. Furthermore, it can become difficult to change the program, since any change may affect code in several other classes. With the mediator pattern, communication between objects is encapsulated within a mediator object. Objects no longer communicate directly with each other, but instead communicate through the mediator. This reduces the dependencies between communicating objects, thereby reducing co ...

Haskell (programming Language)
Haskell () is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research and industrial applications, Haskell has pioneered a number of programming language features such as type classes, which enable type-safe operator overloading, and monadic IO. Haskell's main implementation is the Glasgow Haskell Compiler (GHC). It is named after logician Haskell Curry. Haskell's semantics are historically based on those of the Miranda programming language, which served to focus the efforts of the initial Haskell working group. The last formal specification of the language was made in July 2010, while the development of GHC continues to expand Haskell via language extensions. Haskell is used in academia and industry. , Haskell was the 28th most popular programming language by Google searches for tutorials, and made up less than 1% of active users on the GitHub source code repository.

Yesod (web Framework)
Yesod (; he, יְסוֺד, "Foundation") is a free and open-source web framework based on Haskell for productive development of type-safe, REST model based (where URLs identify resources, and HTTP methods identify transitions), high performance web applications, developed by Michael Snoyman et al. Yesod is based on templates, to generate instances for listed entities, and dynamic content process functions, through Template Haskell constructs to host eDSL content templates called QuasiQuotes, where the content is translated into code expressions by metaprogramming instructions. There are also web-like language snippet templates that admit code expression interpolations, making them fully type-checked at compile-time. Yesod divides its functionality in separate libraries, so you may choose your functionality library of your choice. MVC architecture Controller Server interface Yesod uses a ''Web application interface'' API, abbreviated ''WAI'', to isolate servlets, ...

Pivotal Software
Pivotal Software, Inc. was an American multinational software and services company based in San Francisco that provided cloud platform hosting and consulting services. Since December 2019, Pivotal has been part of VMware. History Pivotal Software was formed in 2012 after spinning out of EMC Corporation and VMware (which was majority-owned by EMC). The name came from the Pivotal Labs LLC which had been acquired by EMC, and briefly used the name GoPivotal, Incorporated. On April 24, 2013, the organization announced a investment from General Electric (for 10% equity) and Pivotal One, including Cloud Foundry for cloud computing. Paul Maritz became Pivotal's chief executive immediately after the spin-out. Maritz had joined EMC in February 2008 when Pi Corporation, a company he co-founded, was acquired and was previously the CEO of VMware. The Greenplum Database (acquired by EMC in 2010) formed the basis of a division selling software for the big data market. In March 2013, a d ...

CodeIgniter
CodeIgniter is an open-source software rapid development web framework, for use in building dynamic web sites with PHP. Popularity CodeIgniter is loosely based on the popular model–view–controller (MVC) development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional. CodeIgniter can be also modified to use Hierarchical Model View Controller (HMVC) which allows the developers to maintain modular grouping of Controller, Models and View arranged in a sub-directory format. CodeIgniter is most often noted for its speed when compared to other PHP frameworks. In a critical take on PHP frameworks in general, PHP creator Rasmus Lerdorf spoke at frOSCon in August 2008, noting that he liked CodeIgniter "''because it is faster, lighter and the least like a framework.''" Source code and license CodeIgniter's source code is maintained at GitHub, and as of the preview version 3.0rc, is certified open source software licensed ...
