HBase is an open-source distributed database system implemented for low latency operations in Hadoop. HBase was previously known as Google Big Table and it is built on Java. HBase uses SQL like queries to extract the data from HDFS(Hadoop distributed file system). HBase has similar features compared to traditional relational models but used for big data applications.
HBase can store billions of rows and millions of columns of data. Companies will have billions of rows of data and it is difficult to retrieve a particular row from the data. HBase can do this in very little time with low latency operations.
