    摘要: The present invention pertains to an apparatus and process for storing information object collections in a database. Examples of such object collections are nested tables and variable length arrays. In an embodiment, the invention provides mechanisms and methods for storing nested tables in either a base table of a database, or an index-organized table. In one embodiment, mechanisms and methods are provided for storing variable length arrays into a table column, as a large object ("LOB"), or as an index-organized table. The invention also provides methods and mechanisms for accessing data from these storage mediums.
