CAN/CSA-ISO/IEC 9075-11:18

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC 9075-11\" throughout. This Standard supersedes CAN/CSA-ISO/IEC 9075-11:13 (adopted ISO/IEC 9075-11:2011). Scope This part of ISO/IEC 9075 specifies an Information Schema and a Definition Schema that describes: The structure and integrity constraints of SQL-data. The security and authorization specifications relating to SQL-data. The features and subfeatures of ISO/IEC 9075, and the support that each of these has in an SQL-implementation. The SQL-implementation information and sizing items of ISO/IEC 9075 and the values supported by an SQL-implementation.
