# How to build a Flask application around an already existing database

There are several tutorials on how to build Flask apps from the ground up. What if we already have a database from another application and we are only interested in utilizing its data?  
An example of such requirement is this [stackoverflow thread](https://stackoverflow.com/questions/17652937/how-to-build-a-flask-application-around-an-already-existing-database) and we shall be adapting [this answer](https://stackoverflow.com/a/19064993). In such a case, we need not worry about recreating the table columns what we just have to declare the needed table(s) names(s) and we will be good to go.

For the purpose of this 1 minute showcase, I have come up with a small and simplified version of a typical blog database shown below.
