In the lifecycle of a project it is typically derived from a logical datamodel , though it may be reverse engineer ed from a given database implementation. A complete physicaldatamodel will include all the database artifact s required to create relationships between table s or achieve performance goals, such as index es, constraint definitions, linking tables, partitioned table s or cluster s. The physicaldatamodel can usually be used to calculate storage estimates and may include specific storage allocation details for a given database system. At present, there are seven main databases in the business market Informix Dynamic Server Informix , Oracle Database Oracle , PostgreSQL Postgres , Microsoft SQL Server SQL Server , Sybase , IBM DB2 DB2 and MySQL . There are a great many other RDBMS systems out there, but these tend either to be legacy databases or used within academia such as universities or further education colleges. A physicaldatamodel on each implementation would be significantly different, not least due to the underlying OS requirements that sit underneath them. Examples would be SQL Server which only run on Microsoft Windows operating systems, while Oracle and MySQL can run on Solaris, Linux and other UNIX based operating systems as well as Windows. This means that the disk requirements, security requirements and many other aspects of a physicaldatamodel will be influenced entirely by the RDBMS that a database administrator or their organization ...

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 .

The physical schema is a term used in data management to describe the files and indexes used to store data in a database management system DBMS . In the American National Standards Institute ANSI four schema architecture, the internal schema was the view of data that involved data management technology. This was as opposed to the external schema that reflected the view of each person in the organization, or the conceptual schema that was the integration of a set of external schemas. Subsequently the internal schema was recognized to have two parts The logical schema was the way data were represented to conform to the constraints of a particular approach to database management. At that time the choices were hierarchical and network. Describing the logical schema, however, still did not describe how physically data would be stored on disk drives. That is the domain of the physical schema . Now logical schemas describe data in terms of relational tables and columns , object oriented classes , and XML tags . A single set of tables, for example, can be implemented in numerous ways, up to and including an architecture where table rows are maintained on computers in different countries.
