FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -What is HBase? HBase is a column-oriented non-relational database management system that runs on top of Hadoop Distributed File System (HDFS). HBase provides a fault-tolerant way of storing sparse data sets, which are common in many big data use cases.

Detailed explanation-2: -HBase is a column-oriented database and the tables in it are sorted by row. The table schema defines only column families, which are the key value pairs. A table have multiple column families and each column family can have any number of columns. Subsequent column values are stored contiguously on the disk.

Detailed explanation-3: -What are the Top Column-Oriented Databases? MariaDB, CrateDB, ClickHouse, Greenplum Database, Apache Hbase, Apache Kudu, Apache Parquet, Hypertable, MonetDB are some of the Top Column-Oriented Databases.

Detailed explanation-4: -Yes, Hbase is known to be a column oriented database (where the column data stay together), the data in HBase for a particular row stay together and the column data is spread and not together.

Detailed explanation-5: -Apache HBase is an open-source, column-oriented, distributed NoSQL database. HBase runs on the Apache Hadoop framework. HBase provides you a fault-tolerant, efficient way of storing large quantities of sparse data using column-based compression and storage.
