Aspects of the present invention relate to methods and system of implementing online database modeling. The method includes providing an database modeling diagram framework. The framework is in communication with an online database, and the online database provides access to live data. The method further includes providing online access to the online database for the database modeling diagram framework via an intermediary API, representing a database structure of the online database in a database model within an interface of the database modeling diagram framework, and populating the database model with live data from the online database. Further, the method includes displaying the database model with the live data from the online database within the database modeling diagram framework interface.
