notability date October 2011 primary sources date October 2011 DocumentDefinition Markup Language DDML is an XML schema language proposed in 1999 by various contributors from the xml dev electronic mailing list . It was published only as a W3C Note, not a Recommendation, and never found favor with developers. DDML began as XSchema , a reformulation of XML Document Type Definition DTD s as full XML documents, so that elements and attributes, rather than declarations, could be used to describe a schema. As development continued, the name was changed to DDML, reflecting a shift away from the goal of replicating all DTD functionality, in order to concentrate on providing a robust framework for describing basic element attribute hierarchy. DDML offered no datatype s or functionality beyond what DTDs already provided, so there was not much advantage to using DDML instead of DTDs. DDML did, however, inform the development of the next generation of XML based schemalanguages, including the more successful XML Schema W3C XML Schema and RELAX NG .

The T schema or truth schema not to be confused with Convention T is used to give an inductive definition of truth which lies at the heart of any realisation of Alfred Tarski s semantic theory of truth .

T theories form the basis of much fundamental work in philosophical logic , where they are applied in several important controversies in analytic philosophy . As expressed in semi natural language where S is the name of the sentence abbrivated to S S is true if and only if S Example snow is white is true if and only if snow is white. The inductive definition By using the schema one can give an inductive definition for the truth of compound sentences. Atomic sentences are assigned truth value s disquotationally. For example, the sentence Snow is white is true becomes materially equivalent with the sentence snow is white , i.e. snow is white is true if and only if snow is white. The truth of more complex sentences is defined in terms of the components of the sentence A sentence of the form A and B is true if and only if A is true and B is true A sentence of the form A or B is true if and only if A is true or B is true A sentence ... x, A x is true if and only if, for some possible value of x , A x is true.

XDR was implemented in SQL Server 2000 and Biztalk Server 2001.

A conceptual schema or conceptual data model is a map of concept s and their Relational model relationships . This describes the semantics of an organization and represents a series of Logical assertion assertion s about its nature. Specifically, it describes the things of significance to an organization entity classes , about which it is inclined to collect information, and characteristics of attributes and associations between pairs of those things of significance relationships . Overview Because a conceptual schema represents the semantics of an organization, and not a database design , it may exist on various levels of abstraction. The original ANSI four schema architecture began with the set of external schemas that each represent one person s view of the world around him or her. These are consolidated into a single conceptual schema that is the superset of all of those external views. A data model can be as concrete as each person s perspective, but this tends to make it inflexible. If that person s world changes, the model must change. Conceptual data models take a more abstract perspective, identifying the fundamental things, of which the things an individual deals with are just examples. The model does allow for what is called Inheritance computer science inheritance in object oriented terms.

Orphan date February 2009 Context date October 2009 In computer science , schema evolution refers to the problem of evolving a database schema to adapt it to a change in the modeled reality. The problem is not limited to the modification of the schema. It, in fact, affects the data stored under the given schema and the queries and thus the applications posed on that schema. Until recently the design of a database was expected to create a one size fits all schema capable of accepting every future change in the requirements, thus, schema evolution was not considered. This assumption, almost unrealistic ... in traditional settings . ref Cite web url http yellowstone.cs.ucla.edu schema evolution index.php Schema Evolution Benchmark title Schema Evolution Benchmark Schema Evolution publisher yellowstone.cs.ucla.edu accessdate 2010 07 29 ref Due to this historical heritage the process of schema evolution ... is the impact of the schema evolution on queries and applications.

Refimprove article date March 2007 Essay like date December 2007 Physical schema is a term used in data management to describe how data is to be represented and stored files, indices, et al. in secondary storage using a particular database management system DBMS e.g., Oracle RDBMS, Sybase SQL Server, etc. . 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.

Unreferenced date December 2009 A logical schema is a data model of a specific problem domain expressed in terms of a particular data management technology. Without being specific to a particular database management product, it is in terms of either relational tables and columns, object oriented classes, or XML tags. This is as opposed to a conceptual data model , which describes the semantics of an organization without reference to technology, or a physical data model , which describes the particular physical mechanisms used to capture data in a storage medium. The next step in creating a database , after the logical schema is produced, is to create the physical schema .
