While Entity Framework Core 1.0 shares some conceptual similarities with prior versions of Entity Framework, it was a completely new codebase designed to be more efficient, powerful, flexible, and extensible, running on Windows, Linux and OSX, and supporting a new range of relational and NoSQL data stores. [15] Entity Framework Core 2.0 was ...
Mentioned in the 2018 book ASP.NET Core 2 Fundamentals on page 219. [6] This implementation uses hi/lo algorithm to generate identifiers. Algorithm uses a high value retrieved from database and combines it with range of low values to generate a unique identifier. High value is from column next_id of table hibernate_unique_key by default. But ...
Database rows are mapped to objects (or class instances). You can build data models based on existing data sources or you can build data models from scratch, which you then use to create data structures (tables, columns, joins) in a data source. The result is that database records can be transposed into Java objects.
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.
Language Integrated Query (LINQ, pronounced "link") is a Microsoft.NET Framework component that adds native data querying capabilities to .NET languages, originally released as a major part of .NET Framework 3.5 in 2007.
The Jet DLL determined what sort of database it was accessing, and how to perform what was requested of it. If the data source was an MDB file (a Microsoft Access format) then it would directly read and write the data to the file. If the data source was external, then it would call on the correct ODBC driver to perform its request.
Weakly typed data retrieval allows for quick code writing, and allows for the data to be used in some fashion when the developer doesn't know beforehand what types will be returned. Further, with some effort, the programmer can extract the value into a variable of the proper type by using the GetFieldType or GetDataTypeName methods of the ...
A database engine (or storage engine) is the underlying software component that a database management system (DBMS) uses to create, read, update and delete (CRUD) data from a database. Most database management systems include their own application programming interface (API) that allows the user to interact with their underlying engine without ...
