The goal of this project is to implement a program that parses an ASCII text-based CSV data file and then transforms that same information to a memory-efficient binary format and writes it to a binary data file. The new binary data file also have multiple index files for efficient record retrieval of values from fields other than the primary key. The program should operate entirely from the command line (no GUI). Developed SQL style command based interface in JAVA for retrieving data using index files and binary database. This project parses user input which is ASCII text based pharmaceutical CSV data file and then transforms that same information to a memory-efficient format and writes it to binary data file. Created hash maps and tree maps for each index files which in turn improved data retrieval.
