Remarks
Typically the identifier of some object on a data source consists of some string that is used in commands that get executed. For example, in the SQL statement, SELECT * FROM mytable, the string "mytable" is a unique identifier of an object in the context under which the statement is running.
Typically a data source has some kind of containment mechanism for objects, such as a catalog, schema, or package. This introduces the need for multi-part identifiers, as a single name no longer suffices for uniquely identifying objects. For example, an Oracle server groups different objects under different users, causing the unique identifier of an object to be qualified with a user name.
Since the format of such multi-part identifiers can vary from one data source to another, there has to be a way to convert a given string into its set of parts and vice versa. This class provides such a mechanism.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
