The paper provides solution with SIMS(seamless integration of multisource spatialdata) technique, three levels storage architecture, two-level-authority model and gives a preliminary probe into how to use component technique to embed GIS in MIS.

The three-level storage architecture is adopted, and data in database is stored combined with files.

Multimedia requests schedule policy based on tertiary storage;

An infrastructure of multimedia server cluster in local network based on tertiary storage;

The Join algorithms of massive relations in relational databases based on tertiary storage are studied in this paper.

A study on storage schema of large scale ontology based on relational database;

With the exponential increasing accumulation of data on the Web,it has been very difficult for the existing storage schemas to satisfy the demand of storing large-scale RDF data efficiently.

Under current ontology storage schema,some problems such as difficult maintenance,low query and inference speed may appear after OWL ontology storing in relational database.

To suit the networking trend of machine design and manufacture, a new method of using XML-based storage model and of data query based on XPath is presented against the problem in data maintenance and interchange of the traditional storage method of the mechanical datasheet.

Focused on the problems of object migration for object-oriented XML data,two approaches based on distributed and centralized storage model are put forward,each of which resolves the OID ambiguity problem.

The paper analyzes three kinds of frequently-used storage models namely DAS,NAS and SAN,compares their similarities and differences.
