1. Impala :
Impala is a query engine that runs on Hadoop. It provides high-performance, low-latency SQL queries on data stored in Hadoop. It is an open-source software. It supports in-memory data processing. It is pioneering the use of the Parquet file format, a columnar storage layout that is optimized for large-scale queries typical in data warehouse scenarios.
2. dBASE :
dBASE was one of the most successful database management systems for microcomputers. It was the first commercially successful database system for personal computers. It is used for creating and manipulating relational databases (RDBMS). DBASE uses procedural functions and commands similar to the BASIC language. It uses simple commands for data manipulation like USE, GO TOP, and more.
