What is the difference between DBMS and RDBMS?
DBMS – Data Base Management System
RDBMS – Relational Data Base Management System or Relational DBMS
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 adds the additional condition that the system supports a tabular structure of 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.
DBMS does not impose any constraints or security with regard to data manipulation it is used or the programmer responsibility to ensure the ACID PROPERTY of the database whereas the RDBMS is more with this regards because RDBMS defines the integrity constraint for the purpose of holding ACID PROPERTY. RDBMS may be or may not be Client Server Database System.
Examples :
DBMS – File System, XML
RDBMS – SQL Server, Oracle

plz provide me dbms interview question and answer………………!!!!!!!!!
Oracle and SQL Server are not RDBMSs! The defining feature of a relational database is that its data structures are all Relations (thus “relational”). Relations consist of values within tuples.
That is not the model used by SQL-based DBMSs. SQL contains many things that are not relational: duplicate rows, duplicate columns, nulls, tables without keys, etc.
SQL borrows certain ideas and terminology from the relational model but the SQL features are quite different from their relational counterparts. For example SQL queries are not true projections, the SQL constraint called “PRIMARY KEY” is not the same thing as a relational primary key, etc.

Dear all,
Appreciate if you could provide the SQL command/way to backup a single table in one database.
Regards,
Yogesh Setia
There is no concept of single table backup. What you can do is to script out the structure of the table along with the data
IMFORMATION WAS QUITE GOOD….THANX FOR THAT..!!
Hi Yogesh,
The way for backing up a single table with a single Query is as follows:-
SELECT * INTO [xxxx] FROM [yyyy]
Note:-
1) [xxxx] is the new table for backup
2) [yyyy] is the existing table from which backup needs to be
created
Note that the target table will not have any indices that the source has
Dear Pinal,
You make SQL Server much simpler than it seems.
I am a hard core fan of you. I found your blog few years back when I was a Sr. Software Engineer. It helped me a lot, later also- when I was the Sr.System Analyst in my previous company. Now working as the incharge of a division. Still loves to read your blog. You are such a nice guy worth being always being with you.
The helps you have done for me yet are beyond words.
I hope once we well meet…
