Forward
This presentation, represent the current situation of HEMIS,Development of 10 Modules of HEMIS by ITCC, SystemIntegration of HEMIS which mostly focus on which architectureand type of integration is feasible for HEMIS.

HEMIS
The HEMIS (Higher Education Management InformationSystems) was established in 2008.[IT Conference]
The goal of HEMIS is to improve management, data collection,and analysis.
Currently, two modules of HEMIS are functional.

11th IT Conference
The ITCC (IT Competence Center of Afghanistan) starteddeveloping 10 modules of HEMIS recently.

Problem ...?
Ghezal Ahmad Zia (Technical University of Berlin) EAI August 11, 2016 11 / 43
System development over the last 20 years has been tended toemphasize core functionality as opposed to integration [iConexio]
Many systems are highly stovepiped and difficult to integrate withother similar systems.

What is System Integration?
Ghezal Ahmad Zia (Technical University of Berlin) EAI August 11, 2016 14 / 43
What is System Integration?
Definition
It is the combination of processes, software, standards and hardwareresulting in the seamless integration of two or more enterprise systemsallowing them to operate as one. [EAI]
Ghezal Ahmad Zia (Technical University of Berlin) EAI August 11, 2016 15 / 43
The Problem
”70% of all code written today consists of interfaces, protocols,and other procedures to establish linkages among various systems”[IBM]
”30% of entire IT budget is spent on building, maintaining, andsupporting application integration” [FORRESTER]

EAI
Enterprise Application Integration or EAI, is a technical termsince the early 2000.
EAI is an approach, or more accurately, a general category ofapproaches, to providing interoperability between the multipledisparate systems.

EAI Architecture
There are two basic architectures to achieve this.[EAI-Architecture]
HUB/SPOKEBUS
Ghezal Ahmad Zia (Technical University of Berlin) EAI August 11, 2016 19 / 43
Hub/Spoke
Uses a centralized broker (Hub) and adapters (Spoke)
Spoke connect to application and convert application data formatto a format which Hub understands and vice versa.Hub on the other hand brokers all messages and takes care ofcontent transformation/translation of the incoming message.

BUS
Bus architecture uses a central messaging backbone (bus) formessage propagation.
Applications would publish messages to bus using adapters.
These messages would flow to subscribing applications usingmessage bus.
Subscribing applications will have adapters which would takemessage from bus and transform the message into a formatrequired for the application.
