ERP And Enterprise Architecture

An ERP system unifies database input, processing and retrieval across business units. ERP applications are deployed across locations and have three areas: a centralized database, clients that input data and submit requests, and an application component connecting clients and database. Enterprise architecture translates business vision into effective enterprise change by defining models of the future state and evolution. The two main ERP architectures are two-tier, where the server handles applications and database, and three-tier client/server, where database and application functions are separated, requiring two network connections between client, application server and database server.

ERP And Enterprise Architecture
- 1. ERP And Enterprise ArchitecturePresented by 08-SE-1008-SE-62
- 2. What is an ERP System?An ERP system is generally a term used to describe a set of applications that unify database input, processing and retrieval as well as multiple other business functions across a wide array of business units. Operations managers often choose to implement a system of ERP apps when they want to standardize processes and streamline functionality across many varying departments within an enterprise.
- 3. ERP ApplicationsAre most commonly deployed in a distributed and often widely dispersed manner.While the servers may be centralized, the clients are usually spread to multiple locations throughout the enterprise.ERP Applications generally have three functional areas of responsibilities:The centralized database- central repository.the clients - here raw data gets inputted, requests for information are submitted.application component that acts as the intermediate between the client and the database.
- 4. Enterprise ArchitectureThe process of translating business vision and strategy into effective enterprise change by creating, communicating and improving key requirements, principles and models that describe the enterprise’s future state and enable its evolution.
- 5. ERP ArchitecturesTwo most commonly employed architectures are :Two-tier Architecture.Three-tier Client/Server Implementation Architecture.
- 6. Two-tier ImplementationsThe server handles both application and database duties. The clients are responsible for presenting the data and passing user input back to the server.This distribution of processing responsibilities remains the same even in the presence of multiple servers.
- 8. Three-tier Client/Server implementation Architecture the database and application functions are separated.This is very typical of large production ERP deployments. satisfying client requests requires two or more network connections.the client establishes communications with the application server which then creates a second connection to the database server.

Transformational ViewImpressions:–Separation of Business and IT domains–Work Activities and Information are the domain of the business–App, Data and Technology are the domain of IT–Business Activities drive the Application Architecture–Business Information drives the Data Architecture–Technology Architecture directly enables data and applications (not business process/function and information)
