DBMS vs. RDBMS
• Relationship among tables is maintained in a RDBMS whereas this not the case DBMS as it is used to manage the database.
• DBMS accepts the ‘flat file’ data that means there is no relation among different data whereas RDBMS does not accepts this type of design.
• DBMS is used for simpler business applications whereas RDBMS is used for more complex applications.
• Although the foreign key concept is supported by both DBMS and RDBMS but its only RDBMS that enforces the rules.
• RDBMS solution is required by large sets of data whereas small sets of data can be managed by DBMS.
DBMS : Data Base Management System
… for storage of data and efficient retrieval of data.
1)A DBMS has to be persistent (it should be accessible when the program created the data donot exist or even the application that created the data restarted). 2) DBMS has to provide some uniform methods independent of a specific application for accessing the information that is stored. 3)DBMS does not impose any constraints or security with regard to data manipulation. It is user or the programmer responsibility to ensure the ACID PROPERTY of the database 4)In DBMS Normalization process will not be present 5)In dbms no relationship concept 6)It supports Single User only 7)It treats Data as Files internally 8)It supports 3 rules of E.F.CODD out off 12 rules 9)It requires low Software and Hardware Requirements. FoxPro, IMS are Examples [b]RDBMS: Relational Data Base Management System[/b] .....the database which is used by relations(tables) to acquire information retrieval Eg: oracle, SQL.., 1)RDBMS is based on relational model, in which data is represented in the form of relations, with enforced relationships between the tables. 2)RDBMS defines the integrity constraint for the purpose of holding ACID PROPERTY. 3)In RDBMS, normalization process will be present to check the database table cosistency 4)RDBMS helps in recovery of the database in case of loss of data 5)It is used to establish the relationship concept between two database objects, i.e, tables 6)It supports multiple users 7)It treats data as Tables internally 8)It supports minimum 6 rules of E.F.CODD 9)It requires High software and hardware
