This program was revived last week. I’ve decided to use SQLite as its backend database. Doc told me that its too slow to access from her computer to my Linux server. The first backend of this one is the Postgresql. I’ve decided to use my newly bought Corelab Postgresql database provider, I’m still in doubt before of the capability of the native ado.net provider of Postgresql (npgsql) that time. Now the Npgsql of Postgresql is in its stable version. But anyways the corelab itself keeps on updating their version of their provider. I like the postgresql though mysql is very popular, I tend to prefer the postgresql (though this blog also uses mysql )
