Enterprise Application Integration

These legacy software solutions, either the packaged product or specifically developed to meet specific organization needs in past, works well even today individually, but they create information islands.

In most cases, each system produces redundant information, which successively creates inconsistent data across enterprise. This results in multiple data entry points, data duplication, and data isolation problems. Such organizations are in need of the Enterprise Application Integration (EAI) services to integrate these systems.

We in some cases, use point to point or middleware based integration for providing EAI services to our clients. Point to point integration is used when number of system to be integrated are two to three. For integrating more systems using point to point integration becomes cumbersome and nonviable. Middleware based integration is better choice for large number of systems. Middleware provides generic interfaces with which all integrated applications pass messages to each other. Each interface defines a business process provided by an application.

e-Zest’s EAI service offerings include following major integration services:

Platform Integration

e-Zest provides platform integration using constituents of web services, services oriented architectures (SOA’s) Messaging, Object Request Broker (ORB), Remote Procedure Call (RPC) and Publish and Subscribe based communication integration.

Data Integration

Our expertise in enterprise technology platforms such as .NET and Java EE provides us with the platforms and tools to extract transform and manipulate data for our clients. In the context of XML, this also involves the greater task of metadata management.

Component Integration

Our integration includes integration at the level of the business logic, transaction management and application services using component architecture of SOAP/XML framework or EJB/Struts framework.

Application Integration

Our application integration services include building web services adapters or writing bespoke adapters on appropriate Middleware. Adapter-based integration forms the backbone for this level. Rules and content routing & event-based transactions and transformations are primary enablers in such integration

Process Integration

Involves the process and workflow modeling approach to integration using business process management (BPM) based approach.
