Companies struggling with integrating existing applications and data into Web and electronic-commerce environments will want to consider OC://WebConnect Enterprise Integration Server (EIS) 1.0. The product provides an application-development framework for linking back-end applications and data to Web-based desktops without replacing existing mid-tier solutions you may have already deployed.
Unlike other integration solutions, such as IBM's MQSeries, that utilise messaging services, EIS provides a development environment that enables companies to encapsulate enterprise applications and data as objects that can be deployed on mid-tier application servers as Java servlets, Enterprise JavaBeans, or as Component Object Model objects.
I found two aspects of EIS especially appealing. First, I did not have to replace any of the existing mid-tier technologies, such as the Netscape and Oracle application servers, that I had on hand in order to use the product.
Second, EIS development support for legacy system connectivity will be a real boon for Web developers. For example, the included development tools give host system Systems Network Architecture applications the appearance of a database application. This support makes it easier for developers to integrate legacy applications into Web environments without the need for extensive host system knowledge.
The Java-based EIS development framework, known as OpenVista, is very easy to understand and use. Developers can easily navigate while creating data access objects, applets, or applications.
The only downside I found with OpenVista is that it ran rather sluggishly at times. This issue aside, EIS worked quite well during my test integration efforts. I was able to successfully create and deploy connectors for both host applications and for some relational data sources. The product also provides linkage for enterprise applications, such as SAP.
Future EIS plans include added linkage for a cadre of application servers. If you are given the task of integrating enterprise applications and data, EIS is worth a look.
