I'm working on a roster system for my workplace and was wondering what the best way of storing roster information in the database would be i.e there are staff members already in the database, and every staff member would have roster information for each day that there is a shift rostered to them - similar to findmyshift.com.
You haven't really given us enough information to go on. However. Barry Williams's library of free data models has a simple model for a Nurses' Roster, which you could adapt for your needs. Find it here.

For users like facebook they will have separate table for each users or all in a single table. Which will be efficient?
SQL doesn't work like that. The paradigm is to have tables that store information about groups of entities, such as companies, people, compact discs. Having a table per entity, i.e. one table for every user, doesn't really make sense, and would be very hard to use.

How one can efficiently store the WebGraph in Relational databases such MySQL for playing with algorithms like PageRank? I think of creating two tables: one for URLs where only distinct URLs will be stored and another outgoing links table, for each url store its outgoing URL. Any ideas or any suggestions for efficient storage?
There are specific databases which where created for such a purpose. Take a look at

is it possible to create a english to SQL app using Part of Speech Tagging. or else please suggest some efficient ways to do this app
I'm not exactly sure what you want to do, but...
There is "FCO-IM (Fully Communication Oriented Information Modeling)". It is relatively unknown, but it allows for "english to sql".
For example, you'd have code such as
There is a person with the name Saman;
Person with name Saman has last name Weerasinghe;
There is a Stackoverflow question with id 8062888;
Person with the name Saman asked Stackoverflow question with id 8062888;
Then you can define the relationships and multiplicity, and generate the tables for your data.

thish is a general question about the "big" database player.
I want to know how these DBMS manage deleted record. In particular: does they free space and re-utilize that free space ?
Hope not to be off topic.
Thank you!
In general, they mark a deleted record as deleted, and they keep track of how much free space is available (and where), and will reuse the storage eventually (for new or updated records), but not necessarily in a timely manner.

When I study about cloud-computing, I usually see these terms: on-premise, off-premise applications. I tried to search them on Google, but no luck. Can anyone please explain these terms to me?
On premises means on location, whereas off premises means remote (in the cloud). For instance if an application runs on an "on-premises" server it means the server is physically in the company. If you have an off-premises solution it's hosted in the cloud or centralized location.
you can always check wikipedia for explanation of technical terms:
