Overview of the ACT Example and Summary of Tasks

In this use case, you create a REST-based client application that helps the members of an actors’ guild called ACT manage and schedule their plays for the year. As part of this on-line system, members need to:

•

Search for plays by their ID number (GET).

•

Update author information (PUT).

•

Create new plays (POST).

•

Delete plays.

This tutorial guide helps you:

•

Create play data in a CSV (comma-separated values) file

•

Create the TDV SQL procedures that read, update, insert and delete data

•

Understand how to create a REST client

TDV Studio deploys REST services to the TDV Web Service.

This tutorial pays special attention to the mapping of procedures to HTTP methods, and the construction of the necessary paths and arguments that make up the REST API for the sample application.

Note: This application is only an example of how you can set up a REST framework. The REST infrastructure in TDV is flexible and does not enforce any specific mapping or operation URL PATH structure.

The base URL for REST services in TDV always includes the following derived components.

Protocol	Hostname	port	dataformat	WebContainerNameSpace
HTTP	localhost	9400	XML	ACTdata
HTTPS	localhost	9402	JSON	ACTdata

The basic required Studio tasks to set up REST

1.

Create procedures in Studio for the REST client actions.

2.

Publish the procedures and supporting resources to the Web service.

3.

Create links between HTTP verbs within Studio and the Web service.

Each of the following verbs is associated with one or more of the procedures defined in Studio. After defining the procedures, you can publish them to the Web service and bind them to a verb. This tutorial focuses on the following procedure and verb associations.

HTTP Verb	SQLScript Procedure
GET	playdataByID
POST	insertPlaydata
DELETE	deletePlaydata

4.

Map the REST client application to the URL from the Studio Web service.
