CIS 3303 - System Architecture and Intergtn - Introduction to Integration

What is the mathematical formula used to calculate the numbers of P2P connections?

n(n-1)/2

*True or false:* P2P model is used by most large organization these days.

*False* Enterprise integration model is used by most large organization these days.

What are the drivers of enterprise integration?

1- Ensures that data in multiple systems is kept consistent 2- Ensures sharing of data between multiple systems 3- Provides a single front-end/ user interface for a number of applications ; no need for users to learn to use different software packages 4- Extracts business policies or rules from applications ; if one of the systems is replaced, no need to code again

Name 5 commonly used integration software.

1- Microsoft Biztalk Server 2- Oracle Service Bus 3- IBM WebSphere 4- SAP NetWeaver 5- Open ESB

A collection of technologies and services which form a "middle-ware" to enable integration of systems and applications across an enterprise. Where all systems are connected to a centralized framework.

Enterprise Integration

Give me an example of enterprise integration framework/model.

Enterprise Service Bus (ESB)

What would life be like without system integration?

No connectivity between system, so the only way to exchange data is by manual process. For example, if a customer wants to change his address, he has to fill manual forms and get signatures.

Involves connecting the different systems to one another, where systems can talk to each other, but it can get very complicated, for example a company with 5 systems will need 10 connections.

Point-to-Point Integration (P2P)

What is Enterprise Integration?

The process of linking together different computing systems and software applications of an enterprise, physically or functionally, to act as a coordinated whole.
