This document summarizes a webinar about using Espresso Logic to create a reactive REST API for SQL database access. The webinar demonstrated how to build a RESTful API from database tables, test the API, add filtering and sorting, create multi-table endpoints, call the API from mobile and web clients, implement authentication and authorization with row- and column-level security. The total demonstration time was 15 minutes. Espresso Logic creates a complete middleware layer to connect mobile and web applications to backend SQL data through REST APIs.
