INTRODUCTION OF RDBMS:

RDBMSs have been a common choice for the storage of information in new databases used forfinancial records, manufacturing and logistical information, personnel data, and other applicationssince the 1980s. Relational databases have often replaced legacy hierarchicaldatabases and network databases because they are easier to understand and use. However,relational databases have received unsuccessful challenge attempts by objectdatabase management systems in the 1980s and 1990s (which were introduced trying to addressthe so-called object-relational impedance mismatch between relational databases and object-oriented application programs) and also by XML database management systems in the 1990s.
