An entity–attribute–value model (EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc—property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforeseeable using a fixed design. The use-case targets applications which offer a large ...
Entity Framework Core 3.0 was released on 23 September 2019 (5 years ago) () along with Visual Studio 2019 16.3 and ASP.NET Core 3.0, [19] Entity Framework Core 3.1 (EF Core 3.1) was formally released for production use on 3 December 2019 (5 years ago) () and will be the preferred long-term supported version until at least 3 December 2022. [20 ...
The provider model is a design pattern formulated by Microsoft for use in the ASP.NET Starter Kits and formalized in .NET version 2.0. It is used to allow an application to choose from one of multiple implementations or "condiments" in the application configuration, for example, to provide access to different data stores to retrieve login information, or to use different storage methodologies ...
ASP.NET Core is an open-source modular web-application framework. It is a redesign of ASP.NET that unites the previously separate ASP.NET MVC and ASP.NET Web API into a single programming model . [ 3 ] [ 4 ] Despite being a new framework, built on a new web stack, it does have a high degree of concept compatibility with ASP.NET.
The most common handler is the ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler. [2] HTTP handlers are an essential component of the ASP.NET framework, providing a low-level way to interact with incoming HTTP requests.
[32] [33] [34] As the framework evolved, additional object–relational tools were added, such as the Entity Framework and LINQ to SQL, both introduced in .NET Framework 3.5. These tools reduced the significance and popularity of third-party object–relational libraries.
Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.
The entity–control–boundary approach finds its origin in Ivar Jacobson's use-case–driven object-oriented software engineering (OOSE) method published in 1992. [1] [2] It was originally called entity–interface–control (EIC) but very quickly the term "boundary" replaced "interface" in order to avoid the potential confusion with object-oriented programming language terminology.
