In this case I am not giving my codes in blog but you can find it in GitHub. Please follow the following links to find the problem and solution. Again this is not dependent on any particular database technology like I am using MS SQL Server here.
Few days ago I got a series of RDBMS related problems for practice. I thought that I should solve them and return. After write some code I change my idea and now I am sharing them with all of my readers. It is always best to write a blog post than mail. The blog post is public and you can share your ideas publicly and if needed you can share the post link to some one privately.
Today I am creating a series of problem and solution. It can be on various subjects. At this moment I am starting with database design. From internet I found some database related problem in which you have to solve the domain design with relational database concept. In my blog I want to share some of these problems with my solution. Please feel free to download the code and review the solution.
