Presentation to understand what are the various types of system integration, and why SOA (Service Oriented Architecture) more specifically Oracle SOA plays an important role in integrating ERP systems.

1. Why to Integrate ?
Business Data
Business Logic
Business Process
Order Management
Inventory Management
Manufacturing
Quote Management
Key Points
• Organizational Goals
• Business Activities
• Various Operations within the Business
• Controlled / Managed by Human resources or
Systems

2. Why to Integrate ?
Order Management
ERP
Inventory Management
CRM
Supplier Management
Sub System
Quote Management
Exchange Customer’s Data
Author : Darley Stephen

3. To connect business processes
To connect business activities & To leverage human communication
To expose business data without compromising the governing implementation
To apply business rule / business logic without impeding the normal operating mode of
the systems that governs various business process within the organization
To reduce implementation effort of transferring or sharing data from one system to
another

Key Drivers
• Handshake btw Domain Experts
• Each Silos (Functions) should address capacity risks
• Throughput and Data traffic
• Versioning of integrated systems
• Scalability
• Extensibility
• Level of Control –depends of integrated systems
• QoS

6. How to Integrate ? Horizontal Integration
Key Drivers
• Identifying and Categorizing the Data to be
integrated
• Identifying and Categorizing the Business Logic /
Rules to be integrated

7. How to Integrate ?
Vertical Integration Star Integration Horizontal Integration
Depends on the Systems to be integrated High Maintenance Cost Low if the Common Service(s) are identified and created, that can act
on similar business logic and business data.
Reusability is not really possible Reusability in the form of duplication. Highly Reusable
Heavily depend on high time and knowledge availability of domain
experts , or personals who has a knowledge of the respective
systems to be integration.
Heavily Depend on high time and knowledge availability of domain
experts , or personals who has a knowledge of the respective
systems to be integration.
Source and Destination Data and Business Logic is what is required
for this integration to be created. In most cases it will be only a
Business Data Transformation that will happen between the Systems
to be integration.
Typically >=3 Types Domain experts are required to successfully
integrate the systems. For example If 2 systems are to be integration,
• Technical (and/or) Business expert of system 1
• Technical (and/or) Business expert of system 2
• Technical (and/or) Business expert of the integration tier
Typically >=3 Types Domain experts are required to successfully
integrate the systems, but also involves subsystems.
Since Horizontal or Enterprise Service Bus integration involves
applying of Business Logic and Mapping / transformation of Business
Data, Typically only 1 Type of Expert who actually design/architects
and develops the in integration Tier, is required.
Success purely depends on a effective handshake and clear
communication between Domain experts of the systems to be
integrated.
Success purely depends on a effective handshake and clear
communication between Domain experts of the systems to be
integrated.
Success depends on
• How the Business data between systems should be mapped or
transformed
• How the Business Logic should be applied on various data to
integrate systems.

11. Why SOA ?
Remove Complexity
Lower Cost of Development and Maintenance
Highly Reusable, Scalable and Extensible
Introduce new Business Logic without changing existing Functionality or Integration
Easy to develop Error Handling Mechanism
Easy to Identify Failures and Repair
Zero impact on Architecture due to End-System upgrades or changes
Loosely coupled , failures will not impact integration
High Availability of SOA service is easy to deploy (Dispatcher)
Helps Business units / Applications to secure Data or server
Parallel Development
Low Operational impact due to integrated systems upgrades or changes
