Abstract factory patternThe abstract factory pattern in software engineering is a design pattern that provides a way to create families of related objects without imposing their concrete classes, by encapsulating a group of individual factories that have a common theme without specifying their concrete classes. According to this pattern, a client software component creates a concrete implementation of the abstract factory and then uses the generic interface of the factory to create the concrete objects that are part of the family. The ...
Active objectThe active objectdesign pattern decouples method execution from method invocation for objects that each reside in their own thread of control. The goal is to introduce concurrency, by using asynchronous method invocation and a scheduler for handling requests. The pattern consists of six elements: A proxy, which provides an interface towards clients with publicly accessible methods.An interface which defines the method request on an active object.A list of pending requests from clients.A scheduler, which decides ...
ADO.NETADO.NET is a data access technology from the Microsoft.NET Framework and .NET that provides communication between relational and non-relational systems through a common set of components. ADO.NET is a set of computer software components that programmers can use to access data and data services from a database. It is a part of the base class library that is included with the Microsoft .NET Framework. It is commonly used by programmers to access and modify data stored in relational database systems, though it can ...
Action–domain–responderAction–domain–responder (ADR) is a software architectural pattern that was proposed by Paul M. Jones as a refinement of Model–view–controller (MVC) that is better suited for web applications. ADR was devised to match the request-response flow of HTTP communications more closely than MVC, which was originally designed for desktop software applications. Similar to MVC, the pattern is divided into three parts. ComponentsThe action takes HTTP requests (URLs and their methods) and uses that input to interact ...*As an Amazon Associate I earn from qualifying purchases.
