Abstract
THE OBJECTIVE OF THIS PROJECT IS TO INVESTIGATE SEVERAL KEY IMPLEMENTATION ISSUES BY DESIGNING AND BUILDING UNIX-BASED PROTOYPE HETERO-GENEOUS QUERY PROCESSING SOFTWARE. THIS SOFTWAREWILL PROVIDE UNIFORM ACCESS TO DATA THAT MAY BE RESIDENT IN MORE THAN ONE DATA BASE AND/OR AT MORE THAN ONE HOST. IT WILL INTERFACE TO PRE-ESTABLISH DATA BASES RUNNING UNDER EXISTING DBMSS WITHOUT REQUIRING ANY MODIFICATION TO THE DBMS PRODUCT, TO THE DATA BEING ACCESSED, OR TO ANY PRO-EXISTING SINGLE HOST APPLICATION SOFTWARE. THE FIRST MAJOR ISSUE TO BE INVESTIGATED IS DISTRIBUTED DATA BASE ADMINISTRATION DESCRIPTIONS OF EACH PARTICIPATING DATA BASE, USER AUTHORIZATIONS, CROSS REFERENCES BETWEEN THE VIRTUAL INTEGRATE VIEWS AND PHYSICAL DATA BASE RECORDS/ FIELDS, PLUS OTHER INFORMATION, WILL NEED TO BE MAINTAINED ON MULTIPLEHOSTS. ADMISTRATION OF THIS NEEDS TO BE AS PAINLESS AS POSSIBLE. THESECOND MAJOR ISUE TO BE INVESTIGATED IS THE PERFORMANCE OF THE QUERY DECOMPOSITION PROCESS THAT BREAKS DOWN A QUERY AGAINST THE INTEGRATED VIRTUAL DATA VIEW TO A SET OF "SUB-QUERIES" AGAINST INDIVIDUAL PHYSICAL DATA BASES THAT COLLECTIVELY "ADD-UP" TO THE ORIGINAL.
