Introduction

Application integration at its simplest is often just one application sending a message to another to notify it of some change. Perhaps when a patient arrives at a hospital, the registration system will send a message to clinical systems so they have all demographic data ready to use. Of perhaps it is just a nightly file transfer from the sales system to the accounting system.

But modern application integration platforms or suites can do a lot more than this to help applications work together and add real value to the enterprise.

Abstract

In a recent benchmark test of an application based on InterSystems Caché, a sustainable rate of 8.9million database accesses/second, with peaks of 16.9 million database accesses/second, was achieved. These results were from a test performed on a connected system of eight applications servers, using Intel Xeon 5570 processors, and running Linux as the operating system. This benchmark shows that:

Introduction

HL7 V2 message routing solutions often have hundreds of business services, processes and operations. Inevitably things will go wrong and you have to monitor the production to be able to react quickly and resolve any problems before they can become serious issues.

Ensemble includes some powerful alerting capabilities that can help, but if you aren't careful you will be inundated with alerts and your inbox more or less becomes a copy of the event log defeating the object of the exercise.

The Business Case for InterSystems Ensemble

This document presents a business case for replacement of older interface engine software with our next-generation rapid integration product, Ensemble. To illustrate the business case, our primary example will be an InterSystems customer (Metro Health Corporation) that replaced its SeeBeyond eGate (now Sun SeeBeyond) interface engine with Ensemble. Other organizations also will comment on reasons for switching to Ensemble.

Introduction

This paper describes how Ensemble behaves after a system crash or similar uncontrolled shutdown or failover. Ensemble is normally configured to start processing messages automatically when the operating system restarts or when the system has failed over to a cluster member or mirror member. No manual intervention is required. But, in order for your system to robustly handle system failure and restart, you must understand how Ensemble handles these conditions and develop your productions using the rules and guidelines in this document.

Use Cases for Unstructured Data

Introduction

Experts estimate that 85% of all data exists in unstructured formats – held in e-mails, documents (contracts, memos, clinical notes, legal briefs), social media feeds, etc. Where structured data typically accounts for quantitative facts, the more interesting and potentially more valuable expert opinions and conclusions are often hidden in these unstructured formats. And with massive volumes of text being generated at unprecedented speed, there’s very little chance this information can be made useful without some process of synthesis or automation.

DTL TechFAQ

Ensemble is based on message flow, and a data transformation is a way to convert from one message type to another. DTL (Data Transformation Language) adds a layer to this - it provides a graphical way to do the conversion. This is really helpful because most of the time, people with domain-specific knowledge may not have extensive coding skills. However, you always have the ability to do some coding, so if you need or want to, this is available.

DTL has several components: the data transformation engine, the language itself, and the DTL editor.

Why You Should Consider the Cloud

Introduction

By now, anybody working in the technology sector will have heard of Cloud computing. But the concept is increasingly being paid attention to outside of IT departments, with growing recognition among boardlevel executives of the potential of this range of innovations. Frequently, senior personnel are hearing stories about how the Cloud helps organizations reduce costs, boost efficiency and expand their operations, so they’ll be excited about what the Cloud can do for them.

Executive Summary

InterSystems HealthShareÆ and InterSystems EnsembleÆ both provide a rapid integration and development platform with built-in capabilities for the high-speed processing of HL7 messages. For the purposes of HL7 v2 message routing the two products are equivalent in performance. For brevity, this document will just say Ensemble in many places but it should be taken to apply equally to both products.

Caché for MultiValue Developers

InterSystems has implemented a broad set of MultiValue extensions for its Caché multidimensional database. These extensions enable the migration of MultiValue applications to Caché and bring the full range of Caché object and SQL development technologies to MultiValue developers. The result: your existing MultiValue investments are preserved, you gain a broad spectrum of highly scalable deployment options, and your developers can combine the best of MultiValue, object, relational, and technologies to extend existing applications and build new ones.

Ensemble Virtual Documents TechFAQ

An introduction to virtual documents

Ensemble virtual documents enable your productions to work with large and complex documents with little overhead.

What is a virtual document?

A virtual document is a special kind of Ensemble message, for use with Electronic Data Interchange (EDI) messages and with XML documents.

How are virtual documents different from standard messages?

Abstract

A global provider of mobile telecommunications software tested the performance of InterSystems Caché and Oracle as the database in a simulated data mart application. They found Caché to be 41% faster than Oracle at building a data mart. When testing the response time to SQL queries of the data mart, Caché's performance ranged from 1.8 times to 513 times faster than Oracle.

BPL TechFAQ

The Business Processing Language - for orchestration and long-running business processes.

Ensemble can orchestrate calls to external systems. Very often this is done to implement or automate a long-running business process - that is, real business processes where people interact with a series of different systems to complete complex tasks. BPL (the Business Processing Language) provides a graphical way to create these orchestrations.

Executive Summary

An accountable care organization (ACO) is a group of providers that are collectively responsible for the total cost and quality of care provided to a specific population of patients. Together, the group assumes risk and shares rewards. As with high-performing organizations in other industries, the hallmarks of ACOs are quality measurement and continuous improvement.

How do you balance the need to achieve an early success with SOA against the requirement for an architecture that will deliver long term success? You don't want to get bogged down in architectural committees for three years, but you don't want to make short term decisions that will be roadblocks to long term success.

Executive Overview

One way financial services firms can improve their operational efficiency is to revamp their data management infrastructure. Creating a central repository for data that is used by multiple applications can ensure data consistency and quality across the enterprise, ease integration bottlenecks, and lower the number of failed trades.However, different applications have different database usage patterns. To satisfy them all, any central data repository must:

Strategic Interoperability

Executive Overview

This white paper discusses the critical requirements for the U.S. Departments of Defense (DoD) and Veterans Affairs (VA) to share Service members’ medical records – including real-time access to a complete composite health record – and it proposes an immediate solution via implementation of a health informatics platform. This approach will provide significant and clearly visible results in a matter of months, while positioning the Departments for strategic improvements in the years ahead.
