A beginner’s guide to position Ensemble in regards to MicroServices Architecture (MSA). MSA is getting more visibility in the Enterprise Java world therefore it is vital to understand what is behind the buzz. I make a (humble) attempt to write my view and share with you.

Beginner’s guide to RESTful Application Program Interface (API) design and documentation. Through the example you will learn some common pattern for RESTful API.

Before you read

You need to know

This article gives a brief introduction how a RESTful service consumer and a RESTful service provider exchange data. It is a beginner’s guide. Data is transferred from a consumer to a provider as parameters of the service. Parameters are part of a service request. The result of the service action a response is returned from a provider to a consumer. Both the service request and response are standard HTTP messages. Since HTTP is a flexible standard regarding to the message contents, RESTful services also enjoy the versatility of data transfer methods.

Cross-origin Resource Sharing (CORS) is one of the basic security features built into browsers. CORS controls accessing resources from a HTML page in domains other than the original domain. It is particularly important for AJAX calls. Since RESTful services can be used as data provider to any AJAX call, you have to be able to control cross-origin access. By default services are not allowed to do CORS. You are going to learn how to enable it for Ensemble RESTful services.

Today I'm releasing a new EWD 3 module - ewd-feder8.

ewd-feder8 is a federation or integration platform, built as an extension of the EWD 3 ewd-xpress module. So what does it do and what's it for?

It's all about federating and integrating multiple web or REST service end-points.

At its simplest you can use it as a proxy server in front of a remote web service or REST end-point.

Getting around to wrapping up a short tour in Professional Playtime, I wanted to share my experience at the HIMSS FHIR Connectathon I participated in out in Indy in April.

Presenter: Danny Wijnschenk
Task: Build a development stack that enables state-of-the-art rapid development with a stable but adaptive back end.
Approach: Use InterSystems’ new document data model to achieve modern full-stack development

The MEAN stack is a very popular stack for building applications quickly that can change at a rapid pace. We will explore the benefits of such a stack and how you can tackle the requirements for modern and fast paced front-end development with support of a stable, but yet adaptive back-end using our new document data model.
