Presentation Transcript


  • integrate (or attempt to integrate) all data and processes of an organization into a unified system

  • use multiple components of computer software and hardware

  • use of a unified database to store data for the various system modules

  • attempt to cover all basic functions of an organization



  • a software package generally would only need to provide functionality in a single package that would normally be covered by two or more systems.

    e.g., payroll and accounting functions would be considered an ERP software package.

  • eliminates the need for external interfaces previously required between systems

Three tier software architectures
Three Tier Software Architectures

Emerged in the 1990s to overcome the limitations of the two tier architecture

  • user interface (client)

  • process management where business logic and rules are executed and can accommodate hundreds of users

  • data management (server) components

Increased performance, flexibility, maintainability, reusability, and scalability, while hiding the complexity of distributed processing from the user

Middle process management tier
Middle process management tier

  • control transactions and asynchronous queuing to ensure reliable completion of transactions [Schussel 96].

  • manages distributed database integrity by the two phase commit process (Database Two Phase Commit).

  • provides access to resources based on names instead of locations, and thereby improves scalability and flexibility as system components are added or moved [Edelstein 95].

Two tier software architectures

User System Interface (such as session, text input, dialog, and display management services)

Processing Management (such as process development, process enactment, process monitoring, and process resource services)

Database Management (such as data and file services)

Two Tier Software Architectures

Disadvantages and display management services)

  • Inadequate investment in ongoing training

  • Undercapitalized - ERP system is often operated by personnel with inadequate education in ERP

Risks and display management services)

  • Personnel turnover

  • Customization of the ERP software is limited

  • Re-engineering of business processes to fit the "industry standard" prescribed by the ERP system may lead to a loss of competitive advantage

  • very expensive to install

  • ERP vendors can charge sums of money for annual license renewal

  • Technical support personnel often give replies to callers that are inappropriate for the caller's corporate structure.

  • too rigid and too difficult to adapt to the specific workflow and business process of some companies

Risks cont
Risks (cont.) and display management services)

  • Systems can be difficult to use

  • Can suffer from the "weakest link" problem

  • Many of the integrated links need high accuracy in other applications to work effectively

  • Switching costs are very high

  • Blurring of company boundaries can cause problems in accountability, lines of responsibility, and employee morale

  • Resistance in sharing sensitive internal information between departments

  • Compatibility problems with the various legacy systems of the partners

  • The system may be over-engineered relative to the actual needs of the customer

Service oriented architecture soa principles
Service-oriented architecture (SOA) principles and display management services)

  • Reuse, granularity, modularity, composability, componentization, and interoperability

  • Compliance to standards (both common and industry-specific)

  • Services identification and categorization, provisioning and delivery, and monitoring and tracking


Soa specific architectural principles
SOA- and display management services) specific architectural principles

  • Service Encapsulation

  • Service Loose coupling - Services maintain a relationship that minimizes dependencies and only requires that they maintain an awareness of each other

  • Service contract - Services adhere to a communications agreement, as defined collectively by one or more service description documents

  • Service abstraction - Beyond what is described in the service contract, services hide logic from the outside world

  • Service reusability - Logic is divided into services with the intention of promoting reuse

  • Service composability - Collections of services can be coordinated and assembled to form composite services

  • Service autonomy – Services have control over the logic they encapsulate

  • Service optimization – All else equal, high-quality services are generally considered preferable to low-quality ones

  • Service discoverability – Services are designed to be outwardly descriptive so that they can be found and assessed via available discovery mechanisms[7]
