thanks for the suggestion, but the details of the project says it has been written in java? I look for in free pascal / lazarus
Actually I understand you need an example about a dentist software. Sorry about this.
But dentist software, grocery , marketing , billing etc software means related about a sector and generally uses a kind of database for operations of customer , productions etc.
There is no easy way to create a new software but I believe you can create a new one.
