My problem is I need to develop a sales application to be used on 5 computers. The database needs to stay on a main computer and other computers should connect with that over LAN.
I donot want to use SQL Server as it is too complicated to give permissions, setting up firewalls etc. for the end user.
Is that any type of database that could serve my purpose, without giving sharing violation error?
You have two options either you can go for Server Client DB like MySQL or you can try embedded databases like vista db(These are less complicated).
However for better performance its better to use a proper server client db.

Im trying to understand more about SQL injection, I know how it works and how to protect against it, but I just have a few questions.
What are typical 'programming' sources of vulnerability to SQL injection exploit?
What are typical 'system' and coding mechanisms that can be used to protect against SQL injection?
I would appreciate straight answers not links as I dont find them useful.
Thank you

Solutions:
Use prepared statements.
Validate input types (may be redundant if above point is used correctly).

i have a few thousand rows of data and i'm connecting to the db via VPN.
retreiving data over VPN is pretty slow and i'm looking for ways to
improve performance. is pagination of results a good way to go?
It always depends on how you are using pagination. If you are returning all the data and only displaying 10 rows at a time on the client then it would not change anything. If you are truly getting only 10 records at a time from the DB then it could help. However 1000's of rows should be nothing for any database platform or any network connection to provide. I would look into the query to ensure it is optimized.

Can I use free SQLServer Express in my commercial windows project? Are there any license issues? How many nodes it supports in multiuser environment ?
Quick answer is Yes. I have heard of MS themselves say it is OK. See this MSDN forums thread.
SQL Server Express is distributed for free and can be used reliably in any small business application.
The Wikipedia article is quite good at highlighting the key drawbacks of using an Express edition compared to a commercial SQL Server instance. Most notable perhaps is the lack of a SQL Server Agent process, which is usually used for job scheduling.

In your workplace, where do you store your common, non-database specific scripts that you use in SQL Server? Do you keep them in .SQL scripts on the file server, do you store them in the Master database, or do you keep them in a database you defined specifically for these kinds of things?
We store them as regular source code, so in version-control.
You have then available previous versions of script, and you avoid "someone deleted the XY script" risk.
We store them in a wiki where everyone can access them.
We store them in a separate database and have a custom program for easy execution and maintenance.
I horde them all in template format on my hard drive. CTRL+SHIFT+M will fill the placehoders. It's great.

What are the differences between MySQL and Sql server?
What are the parameter to chose between the two?
Several questions here related to DB comparisons of various flavors:
What are the major differences between databases?

Where to find a good reference when choosing a database?
postgresSQL mysql oracle differences
The paramater to choose between the two is the price tag. How much do you "expect" to pay for your database. If its zero then MySQL is probably good enough for you, if its 10k then SQL Server is probably good enough for you.
As for the actual differences, there are too many to list.
