In computer programming, a virtual method table ( VMT ), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding ). Whenever a class defines a virtual function (or method ), most compilers add a hidden member variable to ...
C# has a unified type system. This unified type system is called Common Type System (CTS). [104]: Part 2, Chapter 4: The Type System A unified type system implies that all types, including primitives such as integers, are subclasses of the System. Object class. For example, every type inherits a ToString method.
In object oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact class. Rather than by calling a constructor, this is done by calling a factory method to create an object. Factory methods can either be specified in an ...

A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table. Dictionaries contain a collection of objects, or records, which in turn have many different fields within them, each containing ...
Apache Ignite is an in-memory computing platform that is durable, strongly consistent, and highly available with powerful SQL, key-value and processing APIs. With full SQL support, one of the main use cases for Apache Ignite is the in-memory database which scales horizontally and provides ACID transactions. ArangoDB.
Passive data structure. In computer science and object-oriented programming, a passive data structure ( PDS ), also termed a plain old data structure or plain old data ( POD ), is a record, in contrast with objects. It is a data structure that is represented only as passive collections of field values ( instance variables ), without using ...
Boxing is the operation of converting a value of a value type into a value of a corresponding reference type. [7] Boxing in C# is implicit. Unboxing is the operation of converting a value of a reference type (previously boxed) into a value of a value type. [7] Unboxing in C# requires an explicit type cast. Example:
