ABSTRACT:
A method and apparatus for implementing directory services, such as X.500 and LDAP in a SQL environment, and for providing a desired level of indexing, extensibility and scalability. In the directory service system, a plurality of objects are defined to be hierarchical, and the relationships among objects follow a tree structure where each object has a parent object and except for a root, each parent can have zero or more children. The database comprises at least one table having a plurality of rows and columns and stores a plurality of data items, each having a value, each being related to one of a plurality of data types and each having attributes defined by the directory. The attributes of the directory are arranged in a row-per-data type and value format, resulting in a representation identified as meta-data, wherein values are represented per row bydata type: identifying one of said plurality of data types,syntax: identifying the nature of the data type, andvalue: identifying the data value.In the application of metadata to directory services, such as X.500 or LDAP, a ‘PROPERTY table’ is provided in which object name and parent name is added to the ‘principal design’. Other arrangements of tables and attributes provide for the achievement of the system goals.
