Build RESTful Services in Oracle APEX

RESTful services, also known as RESTful web services or REST APIs, are web services that adhere to the principles of Representational State Transfer (REST). REST is an architectural style for designing networked applications. It relies on a stateless, client-server communication protocol, typically HTTP.

Oracle REST Data Services (ORDS) is a powerful tool that simplifies the process of developing and deploying RESTful web services for Oracle databases, including those used with Oracle Application Express (APEX).

• ORDS is a Java-based web application that allows you to create RESTful services to access Oracle databases.

• It provides a way to expose database objects like tables, views, and stored procedures as RESTful web services.

ORDS allows you to create, manage, and deploy RESTful web services, enabling clients to interact with database resources using standard HTTP methods (GET, POST, PUT, DELETE).

In Oracle REST Data Services (ORDS), the structure and organization of RESTful web services are key to managing how different endpoints are defined and behave.There are 4 important terms Modules, Templates, Handlers, and Parameters.

Modules are the top-level grouping of related RESTful services. Think of a module as a container that holds all the related resources and endpoints for a specific area or functionality of your application.

Templates define the URL patterns that map to specific resources and actions within a module. Each template corresponds to a specific endpoint that clients can interact with.

Handlers are the actions or processes that are executed when a specific HTTP method is invoked on a template. Handlers are where the actual logic for interacting with the database or performing operations is defined.

Parameters are used to pass additional data to the handlers. They can be part of the URL path, query string, or request body. Parameters allow you to customize the behavior of your RESTful service based on the input provided by the client.

We will cover all everything mentioned above.
