as you wrote that dbms is not for small organisation or not for small data
why it is so?
plz reply me
difference between dbms and rdbms
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
#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.
