Text Database Compression Using Replacement and Bit Reduction
Anish S. Kumar · 2012
This is a simple compression algorithm which is based on repetition of words and number system theory as well.It employs a technique in which frequently occurring words are replaced by special characters and the modified file is considered as n-base number system, where n is the number of different characters in the file.Further, compression process is carried out by converting this n-base number system to binary number system.The main idea behind using this algorithm is to represent the whole data into lower number system thereby saving bits requirement.It is a simple compression and decompression technique which can be widely used on database as database contains frequently occurring words like last name etc.
