You know something. Life is just not fair. I made such a good application and no one is there to fill the data. I can't believe it. Within few minutes I draw the diagram of this application and I made it so quickly. I even put tooltip for every element of the application. So I was expecting that it will be easy for anyone to fill the data in my application.
And guess what, my manager told me to do the data entry by myself. Initially I was very unhappy about it. But then I thought I made this application; I should be the happiest user to use it.
Now that I'm writing this post, I have already entered the data of more than 200 units and clients with payment details. Practically everything worked fine. Although I was not in a real estate business but my diagram of database and application was just fine. I had included all the aspects of it.

Sehr guten site. Alles arbeitet deutlich, schon eben storungsfrei. Wer machte? Vielleicht vom Weg?,
