Does the underpinning engine differ in the App vs the APIs for Developers?
Nope! The Senzing App is using the same technology and engine as the APIs for Developers. The App utilizes the same APIs exposed in the APIs for Developers offering and is an example of an application that you could construct or integrate.
Can I change the database used by the Senzing App?
No. The app is targeted at single desktop usage with a maximum of 10 million records. As such it embeds a SQLite database only at this time.
Is it possible to integrate the Senzing App with other applications?
It isn't, for integration and solution development the Senzing API for Developers is available.
Where does the App store the data I load?
Ingested data from the data sources you load is stored locally on the same HDD/SDD as the App is installed to.
