This document discusses enterprise application integration (EAI), which addresses integrating information systems within and across enterprises. EAI requires defining data standards, selecting an integration architecture like point-to-point or middleware-based, choosing integration layers, and determining integration methods and technologies. The document outlines the key steps in an EAI implementation: defining data standards and a metadata model; selecting an integration architecture and topology; using methods like data, application, and business integration; and employing technologies like service-oriented architecture.

- 1. Integration – An Introduction EAI addresses the integration of information systems inside of and across enterprises. Unrestricted sharing of data and business processes among any connected application or data sources in the enterprise Source: Gartner Enterprise Application Integration: Presented by: Pradip Nagpal / BPM 1
- 2. Why EAI? Technical Heterogeneity Data Heterogeneity Organizational (Function) Heterogeneity Enterprise Application Integration Methods Data & Standards Technologies Architecture EAI Requires : Step 2: Define Data & Standards Need for global standards for data sharing To achieve this, all data and its location must be • Specified, Recorded, and • A metadata model be built. Examples: SOA, Canonical Data Model Step 1: Select the Architecture • Direct Point to Point Integration • Middleware based Integration A) Select the Integration Topology • Point to Point Integration • Bus • Hub & Spoke B) Integration Layers • Data Layer • Business Layer • Presentation Layer Presented by: Pradip Nagpal / BPM 2
