Based on the MOLAP technology of multi-dimension array,the article proposes a new method of compressed store,which was stored in dimensions by binary code.

Explains the compression storage of the OpenOffice.

The author has,through the combination of sparse matrix compression storage and the characteristics of C/C++ language, produced an improved sparse matrix compression storage method,binary compression storage method,which stores the nonezero elements in the sparse matrix into a sequence list by way of binary scale.

The paper analyzes compress storage of large coefficient matrix which realizes 1D chain compress storage of coefficient matrix by combination of array and structure.

There is data redundancy temporal database and the quantities of temporal database are increasing fleetly,aiming at these problems,this paper puts forward compressed storage tactics based on improved genetic algorithm for temporal data which combine compress technology in existence in order to settle data redundancy in the course of temporal data storage.
