Implementation of decompression algorithm in Alzheimer´s disease database

Databases are convenient and structured methods of sharing and retrieving data. Because of this, they are key components of the information system infrastructure for today´s modern research. This paper presents a decompression algorithm for retrieving information stored in a MySQL database. The database stores genetic information of Malaysian Alzheimer´s disease (AD) patients. Due to the size of the data, previous works have compressed the data for efficient storage. This paper presents a decompression method to retrieve the data and display it to the user. The decompression algorithm was implemented using PHP. Results show that the algorithm has been successfully implemented.
