Executive Summary

The best way to compare the performance of database products is in a head-to-head test using a real application, preferably one of your own. This is especially true when evaluating Caché's post-relational technology, because "standard" transaction processing benchmarking methodologies assume the restrictive "row and columns" format of a relational database. They cannot accurately predict the performance of real applications, which often use complex data models.

Because of contractual prohibitions imposed by well-known database vendors, there is very little published data from

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:

• Support a large number of transactions with high performance
• Provide fast response to queries, using up-to-date information
• P

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.

As a result, Cloud is one of the fastest-growing parts of the IT industry.

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.

Lessons from Aviation

Introduction

Despite rapid advances in information technology and medical devices, most healthcare organizations have not achieved the same high reliability and safety as other industries, such as aviation, where mistakes can have catastrophic results.Executives and physicians alike are dissatisfied with costs and outcomes, and patients are rightfully fearful of medical errors, infections and miscommunication.

Comprehensive patient view, communication and data sharing, and population health management are key components

Federal agencies have been incenting healthcare providers to leverage their electronic health records (EHRs) to get patients involved in the management of their care. Most organizations, however, haven’t moved beyond patient engagement as an item to be checked off in order to receive meaningful use incentive funding.

Typically, providers rely on patient portal functionality that healthcare IT vendors package with their EHR products.

A business case for the transition from eGate to InterSystems EnsembleÆ From interface engine to integration platform Healthcare IT is evolving so rapidly that the term "HL7 interface engine" may soon become extinct. Forces driving this evolution include:

• Government and markets pushing hospitals and integrated delivery networks (IDNs) toward broad-based health information sharing, within and between organizations
• Clinical and administrative staffs needing more information, faster, to improve patient care and control costs
• The need for real-time business intelligence capability to measure

Abstract

A benchmark of a real-world application, which loads data into a data warehouse for subsequent analysis, was performed. To conduct the benchmark, one module of the Oracle-based application was replicated in Caché ObjectScript. Only about 40 person-hours of work was required to duplicate the functionality of the original module in Caché.

The time required to complete certain tasks was measured running the Caché-based module, and was compared to existing data.

Introduction

With the growing popularity of smart phones and tablet computers, consumers are coming to expect that software solutions will be presented as "apps" on their mobile devices. The challenge for most application developers is to find ways to make their existing solutions run on modern mobile platforms without incurring the delay and cost of a complete rewrite.

This paper will describe the approach taken by HAPO Community Credit Union when they adapted their online banking application, developed on InterSystems' high performance object database system called Caché, for use with mobile

Executive Summary

For twenty years or more, large financial institutions have been locked in a battle between the need for extremely high performance transaction processing and the demands of downstream applications that can deliver competitive advantage if they can get real time access to this transactional data.When individual database servers could no longer handle simultaneous transaction and query workloads, many firms turned to replication, offloading data access onto read-only copies of production databases.

Executive Overview

The healthcare software market offers exciting and significant growth opportunities. Yet, while some healthcare software companies enjoy incredible growth, others under-perform, languish, or even fail. There are many criteria for success in this market, but two are particularly critical:

• Breakthrough solutions: In every part of the world, healthcare buyers are demanding broad and deep new capabilities that eliminate cumbersome processes, deliver breakthrough results, and advance the missions of their rganizations.

• Connected care capabilities: the future of healthcare depends

InterSystems Caché 2015.1 soars from 6 million to more than 21 million end-user database accesses per second on the Intel® Xeon® processor E7 v2 family compared to Caché 2013.1 on the Intel® Xeon® processor E5 family

Overview

With data volumes soaring and the opportunities to derive value from data rising, database scalability has become a crucial challenge for a wide range of industries.In healthcare, the rising demands for healthcare services and significant changes in the regulatory and business climates can make the challenges particularly acute.

Introduction

Australia's recent launch of the Personally Controlled Electronic Health Record (PCEHR) - a significant step towards establishing a national e-Health infrastructure - has simultaneously provided a boost to shared Electronic Patient Record (EPR) projects and delivered a wake-up call to healthcare providers about their readiness for connected care initiatives. In countries around the world, the era of connected care is here.

The PCEHR has increased both the push and pull factors that will lead to widespread shared EPR adoption.

Introduction

Impedance mismatch is a term commonly used to describe the problem of an object-oriented (OO) application housing its data in legacy relational databases (RDBMS). C++ programmers have dealt with it for years, and it is now a familiar problem to Java and other OO programmers.

Impedance mismatch arises from the inherent lack of affinity between the object and relational models.

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.

The behavior in the event of a restart is very

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.

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?

The body of any Ensemble message is represented by a persistent class that has one property for each value that the message is intended to carry.

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.

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.

If your first project is to deploy a small number of reusable services in a matter of months but you know that four years from now you might have hundreds of services, an enterprise SOA infrastructure and specialized governance technology you have a dilemma.

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.

Lots of terms have come into use over the years to

Are you new to Ensemble? InterSystems provides several tools to learn the basics of Ensemble and get on your way to becoming an expert in the technology. Before installing Ensemble, take a look at the Ensemble Technology Overview and Getting Started with Ensemble in documentation. Respectively, these documents explain features and major components of Ensemble as well as how to install the software.

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.

These notes are based on experience of other customers who have set up alerting and will hopefully
