1. HBase: This model is used to provide random access to a large amount of structured data. It builds on the top of the Hadoop file system and is column-oriented in nature. It is used to store the data in HDFS. It is an open-source database that provides data replication. Three important components of HBase are HMaster, Region server, and Zookeeper. 

Applications:

  • Internet of Things (IoT)
  • fraud detection applications
  • product catalogs 
  • messaging applications
  • web applications

2. PostgreSQL: PostgreSQL is a powerful, open-source Object-relational database system. It provides good performance with low maintenance efforts because of its high stability. PostgreSQL was the first DBMS that implemented the multi-version concurrency control (MVCC) feature. 

Applications:

  • Financial Industry
  • Government GIS data
  • Web Technology
  • Scientific data
