Embodiment Construction

[0047] First, the features of the X500 model will be described. The X500 model is based on the directory information base DIB. DIB and its structure are defined in ITU-T Rec.X501-ISO / IEC 9594-2. In order to make the present invention easy to understand, the main features of the X500 will be explained subsequently.

[0048] The DIB consists of information about objects. A DIB consists of (directory) entries, where each (directory) entry consists of a collection of information about an object. Each entry consists of attributes. Each property has a type and a value. The entries of the DIB are arranged in the form of a tree, which is a directory information tree DIT, in which vertices represent entries. Entries higher in the tree (closer to the root) will often represent objects such as countries or organizations, while entries lower in the tree will represent people or application processes.

[0049] For example, the entry {C=GB, L=Winslow, O=Graphic Services, CN=LaserPrint...

Abstract

A method for mapping an X500 data model onto a relational database comprising the steps of: - building object classes, each comprising a list of its attributes (8), - building attributes (8), each comprising its type (9), - building a static directory information tree, SDIT, comprising only static DN, SDN, that is DN comprising only static RDN, that is RDN with any variable value removed, - mapping X500 data to RDB by associating - an X500 object class to a RDB table 11 - an X500 attribute (8) to a RDB table column (14) and storing the name (13) of said table column (14) with said X500 attribute (8), as an address pointing to said attribute (8).

Description

Technical field [0001] The technical field of the present invention is the field of databases.The database is known to collect and organize data in a practical manner to store, modify, retrieve and analyze the data. Background technique [0002] There are some examples of database organizations.Provide data in the form of an object. Each object is a piece of data and gather multiple attributes related to the object. Each attribute contains names or types and values. [0003] One of the most common examples is the relationship between the database RDB.In the relationship database, the data is stored in the table, and the table is also called relationship.The name of the column is the name of the attribute, and each object corresponds to the line in the table, which contains the value of the corresponding attribute. [0004] The relationship database has been known as a public.They have proven to be a powerful way to store data.They have been widely used around the world, and many ...
