The listed differences below make it understandable why HBASE is popular in Hadoop (or Bigdata) platform.  5 HBase Vs. RDBMS Top Functional Differences Here're the differences unlock now. Random Accessing HBase handles a large amount of data that is store in a distributed manner in the column-oriented format while RDBMS is systematic storage of a database that cannot support a random manner for accessing the database. Database Rules RDBMS strictly follows Codd's 12 rules with fixed schemas and row-oriented manner of database and also follows ACID properties.

How IBM Cloudscape supports online and offline Backups

IBM Cloudscape is a Java-enabled Object Relational Database Management System (ORDBMS). It supports complex SQL statements, transaction management, and provides multi-user support in the Database Management System (DBMS). You can create two types of backups of the Cloudscape database, online backup and offline backup. You can make backups of a database and the log file of the database. When restoring the database, you need to restore the log file and the database. The below picture shows structure of Cloudscape system. You need to understand the structure and contents of a Cloudscape system in order to make backups and restore Cloudscape databases. A Cloudscape system consists of a system directory, one or more Cloudscape databases, and the system properties and configuration settings. A system directory contains a properties file called and an information and error log file called db2j.log. Each database in a Cloudscape system is stored in a subdirectory,
