How to edit preloaded SQLITE database

It is a very common situation, when you download a ready made application from Github, and you need to upgrade or improve the functionality of the coding, and the previous programmer did not save the data in the source code, instead he saved it in a SQLITE database.

Since this SQLITE database cannot be edited using IDE/Code Editor, hence you need to have a SQLITE editor. One of the choice is SQLitestud, this 16MB executables file can be downloaded from here, and we can use it to edit/delete/create data entry in existing databasename.db.
