    SERIAL8 - Auto-incrementing 80bit proprietary integer. Deprecated

    IDSSECURITYLABEL - stored LBAC security labels

    DISTINCT() - Used to define a distinct named user-defined data type with the same storage attributes as the named base type. Ex: Lira DISTINCT( DECIMAL(20,5) )

    OPAQUE - Stores a user-defined data type whose internal structure is unknown to and inaccessible to the database server

    ST_LineString - Stores a one-dimensional object as a sequence of points defining a linear interpolated path

    ST_MultiLineString - Stores a collection of ST_LineString data types

    ST_MultiPoint - Stores a collection of ST_Point data types

    Why are data types used in RDBMS?

    Different RDBMS support different types. Data types are used in RDBMS and other systems in order to maintain data integrity. You would not want your bank balance to become “Freddy Loves Me!” would you? That would be kind of useless. So your bank uses a datatype that only permits floating point numeric values to be stored in your account balance column.

    There are some basic types supported at least by most RDBMS:

    SMALLINT (16bit binary integer)

    INT/INTEGER (32bit binary integer)

    FLOAT (32bit IEEE floating point numeric)

    DOUBLE (64bit IEEE floating point numeric)

    CHAR (fixed length character strin
