Dear shabir hi as you wrote that dbms is not for small organisation or not for small data why it is so? plz reply me thanx
Probably you are referring to the following article of mine. What is the Difference between DBMS and RDBMS? I guess you need to read it once again as I did not found anything like what you have mentioned.
You had already requested this in a article in ethical hacking dont spam the board with theses same post being repetative.
#1 A DBMS has to be persistent, that is it should be accessible when the program created the data ceases to exist or even the application that created the data restarted. A DBMS also has to provide some uniform methods independent of a specific application for accessing the information that is stored. RDBMS is a Relational Data Base Management System Relational DBMS. This adds the additional condition that the system supports a tabular structure for the data, with enforced relationships between the tables. This excludes the databases that don't support a tabular structure or don't enforce relationships between tables. #2 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 whereas the rdbms is more with this regard bcz rdbms difine the integrity constraint for the purpose of holding ACID PROPERTY. #3 DBMS are for smaller organizations with small amount of data, where security of the data is not of major concern and RDBMS are designed to take care of large amounts of data and also the security of this data.
