Figure 5–1 illustrates the structure of metadata storage in Oracle Internet Directory. This diagram illustrates, in a tree-like format, the Oracle Label Security entries in an Oracle Context: The "tree" has six horizontal levels. At the top level is a single box containing the words "Oracle Context". The second level contains three boxes connected to the Oracle Context: Products, Groups, and Sales, an example database. The Sales box, on the right, has three child-boxes: OracleDBAdmins Group, User-Schema Mapping (example), and Networking. The middle box is titled "Groups," and has five groups listed: OracleDBCreators, OracleContextAdmins, OracleDBSecurityAdmins, OracleUserSecurityAdmins, and OraclePasswordAccessibleDomains. Products, on the left, has two child-boxes: Common, with a nickname attribute, and Oracle Label Security. Thus the third level consists of the children of Products and of Sales: Common, Oracle Label Security, OracleDBAdmins Group, User-Schema Mapping (example), and Networking. The fourth level consists of a single box labeled Policies, connected to Oracle Label Security. The fifth level consists of the n children of Policies, each labeled PolicyN and containing Policy Options. The sixth level shows eight boxes, each representing a type of data stored in a policy, as follows: labels, audit options, levels, compartments, grouops, profiles, policy creators, and database servers.
