MAXIMIZING SYSTEM RESOURCES USED TO DECOMPRESS READ-ONLY COMPRESSED ANALYTIC DATA IN A RELATIONAL DATABASE TABLE

摘要

A method, computer program product and system for minimizing system resources used to decompress read-only compressed analytic data in a relational database table. An i-code list associated with a relational database table is converted into a programming language. The programming language is compiled in object code and stored in a module in the user's system. The object code is called with a pointer designating the particular row in the database containing the compressed data to be decompressed. The compressed data designated by the pointer is decompressed upon execution of the object code. By having the source code for decompressing the compressed data stored as object code in the user's system, the interpretation step (as used in the i-code method) is avoiding thereby reducing the number of machine cycles used to decompress the compressed data. As a result, query programs will be able to access large amounts of data more quickly.
