1Entity–attribute–value model — (EAV) is a data model to describe entities where the number of attributes (properties, parameters) that can be used to describe them is potentially vast, but the number that will actually apply to a given entity is relatively modest. In… …
2Entity-attribute-value model — (EAV), also known as object attribute value model and open schema is a data model that is used in circumstances where the number of attributes (properties, parameters) that can be used to describe a thing (an entity or object ) is potentially… …
3Key exchange — is any method in cryptography by which cryptographic keys are exchanged between users, allowing use of a cryptographic algorithm. If Alice and Bob wish to exchange encrypted messages, each must be equipped to decrypt received messages and to… …
4Entity-relationship model — A sample Entity relationship diagram using Chen s notation In software engineering, an entity relationship model (ERM) is an abstract and conceptual representation of data. Entity relationship modeling is a database modeling method, used to… …
5Entity integrity — In the relational data model, entity integrity is one of the three inherent integrity rules. Entity integrity is an integrity rule which states that every table must have a primary key and that the column or columns chosen to be the primary key… …

7Entity Bean — An Entity Bean is a type of Enterprise JavaBean, a server side J2EE component, that represents persistent data maintained in a database. An entity bean can manage its own persistence (Bean managed persistence) or can delegate this function to its …
8Key server (cryptographic) — In computer security, a key server is a computer mdash; typically running special software mdash; which provides cryptographic keys to users or other programs. The users programs can be working on the same network as the key server or on another… …
9Weak entity — In a relational database, a Weak Entity is an entity that cannot be uniquely identified by its attributes alone; therefore, it must use a foreign key in conjunction with its attributes to create a primary key. The foreign key is typically a… …
10Cryptographic key types — One of the most important aspects of any cryptographic system is key management; it is also the aspect which is most often neglected.[citation needed] A very common mistake is mixing different key types and reusing the same key for different… …
