A standard datamodel or industry standard datamodel ISDM is a datamodel that is widely applied in some industry, and shared amongst competitors to some degree. They are often defined by standards bodies , database vendor s or operating system vendor s. When in use, they enable easier and faster information sharing because heterogeneous organizations have a standard vocabulary and pre negotiated semantics, format, and quality standards for exchanged data. The standardization has an impact on software architecture as solutions that vary from the standard may cause data sharing issues and problems if data is out of compliance with the standard. The more effective standard models have developed in the banking, insurance, pharmaceutical and automotive industries, to reflect the stringent standards applied to customer information gathering, customer privacy , consumer safety , or Just In Time business just in time manufacturing .

The associative model of data is an alternative datamodel for database systems. Other data models, such as the relational model and the object datamodel, are record based. These models involve encompassing attributes about a thing, such as a car, in a record structure. Such attributes might be registration, colour, make, model, etc. In the associative model, everything which has discrete independent existence is modeled as an entity, and relationships between them are modeled as associations. The granularity at which data is represented is similar to schemes presented by Chen Entity relationship model Bracchi, Paolini and Pelagatti Binary Relations and Senko The Entity Set Model . A number of claims made about the model by Simon Williams, in his book The Associative Model of Data , distinguish the associative model from more traditional models. Discussion In an associative database management system, data and metadata data about data are stored as two types of things Items, each of which has a unique identifier and a name. Links, each of which has a unique identifier, together with the unique identifiers of three other things, that represent the source, verb and target of a fact that is recorded about the source in the database. Each of the three things identified by the source, verb and target may each be either a link or an item. Here s how the associative model would use these two structures to store the piece of information Flight BA1234 arrived at London Heathrow on 12 Dec 05 at 10 25am . There are seven items the four nouns Flight BA1234 , London Heathrow , 12 Dec 05 and 10 25am , and the three verbs arrived at , on and at . We need three links to store the data.

For instance, think of A as Authors, and B as Books. An Author can write several Books, and a Book can be written by several Authors. Because most DBMS database management systems only support one to many relationships, it is necessary to implement such relationships physically via a third junction table junction table cross reference table , say, AB with two one to many relationships A AB and B AB. In this case the logical primary key for AB is formed from the two foreign key s i.e. copies of the primary key s of A and B .

Unreferenced date December 2009 Data access typically refers to software and activities related to storing, retrieving, or acting on data housed in a database or other repository. There are two types of data access, sequential access and random access . Data Access is simply the authorisation you have to access different data files.
