  1. Standard data model

    A standard data model or industry standard data model ISDM is a data model 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 .

In the Project lifecycle lifecycle of a project it typically derives from a logical data model , though it may be reverse engineer ed from a given database implementation. A complete physical data model will include all the database artifact s required to create relationships between table s or to achieve performance goals, such as index database index es, constraint definitions, linking tables, partitioned table s or cluster computing cluster s. Analysts can usually use a physical data model to calculate storage estimates it may include specific storage allocation details for a given database system. As of 2012 seven main databases dominate the commercial marketplace Informix Dynamic Server Informix , Oracle Database Oracle , PostgreSQL Postgres , Microsoft SQL Server SQL Server , Sybase , IBM DB2 DB2 and MySQL . Other RDBMS systems tend either to be legacy databases or used within academia such as universities or further education colleges. Physical data models for each implementation would differ significantly, not least due to underlying operating system operating system requirements that may sit underneath them. For example SQL Server runs only on Microsoft Windows operating systems, while Oracle and MySQL can run on Solaris, Linux and other UNIX based operating systems as well as on Windows.

  1. Associative model of data

    The associative model of data is an alternative data model for database systems. Other data models, such as the relational model and the object data model, 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.

    unreferenced date February 2010 File CPT Databases ManytoMany.svg thumb 250px center An Author can write several Books, and a Book can be written by several Authors In systems analysis , a many to many relationship is a type of cardinality data modeling cardinality that refers to the relationship between two entities see also Entity Relationship Model A and B in which A may contain a parent row for which there are many children in B and vice versa. 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 .

A semantic mapper is an essential component of a semantic broker and one tool that is enabled by the Semantic Web technologies. Essentially the problems arising in semantic mapping are the same as in data mapping for data integration purposes, with the difference that here the semantic relationships are made explicit through the use of semantic net s or Ontology information science ontologies which play the role of data dictionary data dictionaries in data mapping. Structure of a semantic mapper A semantic mapper must have access to three data sets List of data elements source Namespace computer science namespace List of data elements in destination namespace List of semantic equivalent statements between source and destination e.g. http www.w3.org TR 2004 REC owl ref 20040210 equivalentClass def owl equivalentClass , http www.w3.org TR 2004 REC owl ref 20040210 equivalentProperty def owl equivalentProperty or http www.w3.org TR 2004 REC owl ref 20040210 sameAs def owl sameAs in Web Ontology Language OWL . A semantic mapper processes on a list of data elements in the source namespace. The semantic mapper will successively translate the data elements from the source namespace to the destination namespace. The mapping does not necessarily need to be a one to one mapping. Some data elements may map to several data elements in the destination. Some semantic mappers are static in that they will do a one time data transforms.

  1. Semantic Grid

    notability date January 2012 confusing date September 2011 The Semantic Grid refers to an approach to grid computing in which information, computing resources and services are described using the semantic data model . In this model the data and metadata are expressed through facts small sentences . Therefore it becomes directly understandable for humans. This makes it easier for resources to be discovered and joined up automatically, which helps bring resources together to create virtual organization grid computing virtual organizations VOs . The descriptions constitute metadata and are typically represented using the technologies of the Semantic Web , such as the Resource Description Framework RDF . By analogy with the Semantic Web, the Semantic Grid can be defined as an extension of the current Grid in which information and services are given well defined meaning, better enabling computers and people to work in cooperation. This notion of the Semantic Grid was first articulated in the context of e Science , observing that such an approach is necessary to achieve a high degree of easy to use and seamless automation enabling flexible collaborations and computations on a global scale. The use of Semantic Web and other knowledge technologies in Grid applications is sometimes described as the Knowledge Grid . Semantic Grid extends this by also applying these technologies within the Grid middleware . Some Semantic Grid activities are coordinated through the Semantic Grid Research Group of the Global Grid Forum .

Semantic translation takes advantage of semantics that associate meaning with individual data element s in one data dictionary dictionary to create an equivalent meaning in a second system. An example of semantic translation is the conversion of XML data from one data model to a second data model using formal ontologies for each system such as the Web Ontology Language owl . This is frequently ... different data models to store their data elements. The process of allowing a single user to search multiple systems with a single search request is also known as federated search . Semantic translation should be differentiated from data mapping tools that do simple one to one translation of data from one system to another without actually associating meaning with each data element. Semantic translation requires that data elements in the source and destination systems have semantic mappings to a central registry or registries of data elements. The simplest mapping is of course where there is equivalence. There are three types of Semantic equivalence Class computer science Class Equivalence .... For example Dan Smith is the same person as Daniel Smith Semantic translation is very difficult if the terms in a particular data model do not have direct one to one mappings to data elements in a foreign data model.
