Abstract: Modern day applications handle large volumes of data. These applications involve real-time data manipulations to be carried within time constraints. So real-time databases are used in most of the real-time applications. For efficient utilisation of database, with no compromise on speed, various compression methods are used to compress the data in a real-time database. In this paper, we propose a two-stage compression process. This process uses two algorithms- Swinging Door algorithm and LZSH algorithm. The survey indicates that this two stage compression results in highly compressed data. The compression time is always less than the database computational time.
Keywords: Real-time database, Data Compression, Swinging Door algorithm, LZSH algorithm.
