Entity Framework (EF) is an open source [2] object–relational mapping (ORM) framework for ADO.NET. It was originally shipped as an integral part of .NET Framework, however starting with Entity Framework version 6.0 it has been delivered separately from the .NET Framework. Entity Framework 6.4 was the latest release of the classic framework.
A typical crosswalk button is an example of an idempotent system. Applied examples that many people could encounter in their day-to-day lives include elevator call buttons and crosswalk buttons. [17] The initial activation of the button moves the system into a requesting state, until the request is satisfied.
JScript .NET is a .NET programming language developed by Microsoft.. The primary differences between JScript and JScript .NET can be summarized as follows: . Firstly, JScript is a scripting language, and as such programs (or more suggestively, scripts) can be executed without the need to compile the code first.
A schema migration is performed on a database whenever it is necessary to update or revert that database's schema to some newer or older version. Migrations are performed programmatically by using a schema migration tool. When invoked with a specified desired schema version, the tool automates the successive application or reversal of an ...
Script.NET has a special quotation operator <[program ]> which returns the AST of a given program. Additionally, the AST of the current program may be accessed with the prog object. Here is an example:
For example, if the subroutine modifies a 64-bit global variable on a 32-bit machine, the operation may be split into two 32-bit operations, and thus, if the subroutine is interrupted while executing, and called again from the interrupt handler, the global variable may be in a state where only 32 bits have been updated.
Idempotent relations have been used as an example to illustrate the application of Mechanized Formalisation of mathematics using the interactive theorem prover Isabelle/HOL. Besides checking the mathematical properties of finite idempotent relations, an algorithm for counting the number of idempotent relations has been derived in Isabelle/HOL.
An idempotent a + I in the quotient ring R / I is said to lift modulo I if there is an idempotent b in R such that b + I = a + I. An idempotent a of R is called a full idempotent if RaR = R. A separability idempotent; see Separable algebra. Any non-trivial idempotent a is a zero divisor (because ab = 0 with neither a nor b being zero, where b ...
