Components of an object type in pl/sql, PL-SQL Programming

Assignment Help:

Components of an Object Type:

An object type encapsulates the operations and data. Therefore, you can declare the methods and attributes in an object type specification, but not exceptions, constants, cursors, or types. You should declare at least one attribute (the highest is 1000); methods are optional. You cannot add the attributes to an existing object type (i.e., the type evolution is not supported).
