Asp.net Reservation sytem
<p>I started implementation of an online reservation system including selection of dates and time. I would like to ask if any free and open source reservation system you can advise me for a start, coz really matters are getting worse :D .. . Also, I still have a little experience in using SQL Server which is a huge pain. </p>

<p>The system is basically a parking reservation that should start with checking the availability(Button) of a parking space by a selecting the departure and arrival date + time of both. After pushing the button the web app. should look in the database for the particular selection and retrieve it back to the user. the problem is that in the web app when i am writing the SQL statement it seems to be wrong. Any help is beneficial.</p>

<p>Regards.   </p>
