Feature details

TMS XData is a full-featured Delphi framework that allows you to create HTTP/HTTPS servers that exposes TMS Aurelius objects through REST/JSON. 

Example of an Aurelius class mapped: 

 

XData enables access via a simple HTTP GET:

 

Example JSON representation of the customer object returned in the body of HTTP response:

 

Use a HTTP POST to create new objects, HTTP DELETE to remove objects, HTTP PUT or HTTP PATCH to update objects.

Example: Change the value of Title property of the customer resource:

 

Easily perform queries on existing objects. 

Example of retrieving customers with country name equal to "USA", ordered by customer's name:

 

Server will return with a JSON array of objects containing all the filtered objects.

Query paging built-in to restrict the number of objects returned in each request.


Sample source Aurelius integrated full server-side logic using methods

Testimonials

BTW I am VERY happy with XDATA in a project I am developing at the moment. Great way to develop distributed applications.

After trying some REST frameworks, my last choice is to use XData! It's really a great framework, very flexible and powerful! TMS Business is a subscription that every serious Delphi developer should have in his toolbox!
