Ideas to connect external database table to wordpress posts as custom field source

After long searches and tries I ended up with “Pods Framework”.

It gives me a choice to store my custom field values to a custom table within wordpress database.

Now i am able to query them with other sources (such as other web apps that shares the same database).
