The main concept for representing data in SQL-99 is the concept of a table, which is made up by a set of columns and rows. A table is associated with a schema and an instance: table specifies the name of the table, the name of each column, and the domains (data types) associated with the columns. A domain is typically referred to by a domain name and has a set of associated values. Examples for basic domains (built-in data types) in SQL-99 are INTEGER, REAL, NUMERIC, CHAR, or DATE. -An instancedoi:10.1007/3-540-48196-6_1 fatcat:n6hoxu4xi5ecfcmf2rlr2ln6le
