SYSTEMS ANALYSIS AND EVALUATION OF METHODS OF DATA COMPRESSION FOR DATABASES LASER COMPLEXES
The purpose of the work is the realization of analysis systems and estimation of properties and principles of operations and the characteristics of data compressions methods. Determination of effective algorithms for reduction of volume of database. In the article the system analysis and algorithms of non-destructive compression of tabular data’s is given. It’s description is given and considered basic advantages and disadvantages. The basic criteria’s for comparison of descriptions of methods and algorithms of data compression are educe. A comparative analysis of the basic non-destructive methods and algorithms is conducted. The results of conducted analyses are testifies in a benefits of algorithms of differential encryption and dynamic algorithms of arithmetical encryption’s.
