Many organizations that are building mobile apps need to connect to and reuse existing (internal) systems. One of the most common system is a relational (SQL) database.

We have prepared two short videos that will show you how to do that using Appery.io API Express.

API Express connects to a relational database and exposes the database tables via REST APIs. Once the APIs are created, the mobile app can easily consume the APIs.

There are two approaches exposing a database:

• Autogenerating the REST APIs
• Creating a custom service for a REST API

The first approach automatically generates CRUD-like APIs to work with a database table. In many apps, this is close to 80% of what an app might need. This automatic approach also comes with very sophisticated offline support. In other words, you app can work offline and sync data with a remote database when a connection is reestablished.

With the second approach, you get full control as you write the actual SQL query (or Stored Procedure) that will be executed. With this approach, you can use a visual service editor to orchestrate the REST API. In addition to the SQL component (connector), you can use connectors such as Web Service (WSDL), REST  and others.
