Hi All,
I am going to develop a small software which searches from the database.
Since the data is small, I thought of using EXCEL, but now my problem is when I sell the software, I dont want the users to view the Excel file and data.

My purpose of application is to search the year of a product from its ID...
User enters the product ID and the application returns the year...
Well the data consists of Product ID and Year... only two columns...
But the rows may extend to 5000.
Since its a small application I dont want any big databases like SQL .
But my data has to be secured.

Keeping data in excel is not a good idea. You may want to check file system databases like SQL lite or SQL CE.///////////

Hi what will be the file format does SQL Lite stored?

Do the customers also needs to be install this for executing the application? In that case many customers doesnt know abt these things...

Also how to secure the data with SQL Lite?
