Concise The definition should use the shortest description possible that is still clear. Non Circular The definition should not use the term you are trying to define in the definition itself. This is known as a circular definition. Distinct The definition should differentiate a data element from other data elements. This process is called disambiguation. Unencumbered The definition should be free of embedded rationale, functional usage, domain information, or procedural information.

Report DefinitionLanguage RDL is a standard proposed by Microsoft for defining reports. RDL is an XML application primarily used with Microsoft SQL Server Reporting Services . RDL is usually written using Visual Studio , although there are also third party tools it may also be created or edited by hand in a text editor. SQL Server Reporting Services or other 3rd party reporting frameworks use RDL to define charts, graphs, calculations, text, images through links and other report objects and render them in a variety of formats. There are three high level sections in a typical RDL file Page style The objects to display including fields, images, graphs, tables.

notability date October 2011 primary sources date October 2011 Document Definition 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 schema languages, including the more successful XML Schema W3C XML Schema and RELAX NG .

Unreferenced date December 2009 A data control language DCL is a syntax similar to a computer programming language used to control access to data stored in a database. In particular, it is a component of Structured Query Language SQL . Examples of DCL commands include Grant SQL GRANT to allow specified users to perform specified tasks. Revoke SQL REVOKE to cancel previously granted or denied permissions. The operations for which privileges may be granted to or revoked from a user or role may include Connect SQL CONNECT , Select SQL SELECT , Insert SQL INSERT , Update SQL UPDATE , Delete SQL DELETE , Execute SQL EXECUTE , and Usage SQL USAGE . In the Oracle database , executing a DCL command issues an implicit Commit data management commit . In PostgreSQL , executing DCL is transactional, and can be rolled back.
