Agenda
Agenda

  • What are EA patterns?

  • Pattern definition.

  • Business architecture blueprint.

  • Information architecture blueprint.

  • System architecture blueprint.

  • Infrastructure architecture blueprint.

  • Governance steps blueprint (lack of time)

  • Summary


What are design patterns
What are design patterns?

  • Design patterns: proven solutions for well known problems.

  • Should reference:

    • Name that describes the pattern

    • Problem to be solved by the pattern

    • Context or settings, in which problems occurs

    • Forces that could influence the problem or its solution

    • Proposed solution to the problem

    • Relations to other patterns and behind the solution

    • Known uses


What are ea patterns
What are EA patterns?

  • EA patterns: proven architecture blueprints for well defined type of enterprises.

  • Should reference:

    • Name of the pattern

    • definitions of a typical enterprise that matches the pattern.

    • Forces that could influence the match between the pattern and enterprise.

    • Blueprints of architectures

    • Relations to other patterns

    • Known uses of the pattern


Pattern definitions
Pattern definitions

  • The "data-centric enterprise"

  • definitions of the typical enterprise:

    • Organization forwhich information is the main asset such as: Intelligent agencies, IRS, Gartner, …

    • Organization which sees data and data sharing across the organization as one of the business main concerns.

    • Used to be central computer organization (MF)


Forces
Forces

  • CEO changed vision, mission

  • Global economic atmosphere

  • Acquisitionsand merges

  • Previous attempts to run EA


Business blueprint
Business blueprint

  • Business processes are integrated and share data.

    • Many lane switching in enterprise BPMNs

  • BP that gather information from different sources into shared repository.

  • BP use data intensively

    • BP success based on data.

  • As a rule of thumb, most users can run any core BP.


Integrated bpm lanes
Integrated BPM lanes

Non data-centric

Data-centric

Grid BP


Business blueprint1
Business blueprint

  • User should work against one integrated system.

  • Need for dynamic and changeable views of information.

  • Duplication of data or data silos exist, hurt the business and should be eliminated


Information blueprint
Information blueprint

  • Information is the atomic element on which the enterprise is based.

  • Classification of BP data:

    • Core/administrative

      • Core

      • Supportive

      • Administrative

      • Its hard to define clear boundaries.

    • Information worlds / By manage users

      • Group of data items managed by well defined group of workers in the enterprise.

      • Those data items managed by the group but accessed by other groups.


Information blueprint1
Information blueprint

  • Shared/Sector

    • Shared: data managed by information world but being used by other users in the enterprise.

    • Sector: data managed by information world. These are NOT used by anyother group.

    • Usually every group works with certain raw data to produce data that will be shared by others.

    • Flower diagram



Information blueprint2
Information blueprint

  • Information worlds expose

    • Visual presentation

    • Information world Logic

    • Data management (CRUD).

  • Information worlds are basic Lego parts for building systems

  • Cross world indexing/Retrieval

  • Each information world should define

    • Access principals to information world

    • Security

    • QoS


Information blueprint3
Information blueprint

  • Mapping existing physical schemas to information worlds.

  • Possibility of historical archive for unused data.

  • Information worlds solve semantic ambiguities for the same notion in different worlds.

    • Telephone, Bank account

  • Create common enterprise syntax.

  • Prevent duplications and silos


Systems blueprint
Systems blueprint

  • System as a host for information world.

    • System: gathering of information worlds with workflow.

  • System of Systems (SOS).

    • Systems developed by different groups in different times should be operated as one system, from the user point of view.

    • Exposing interfaces and services for current and future systems.

      • Technical dependant

      • Technical neutral


Systems blueprint1
Systems blueprint

  • Using HTML presentation to get:

    • Integrated systems on one screen.

    • Enable swift flow and calling stack while moving between systems.

    • The same look and feel for all systems

    • Personalization of views.

  • Basic system structure:

    • Information world

    • Logic/flow

    • Expose services

    • Consume services


  • Systems blueprint2
    Systems blueprint

    • ODP systems.

      • 8 RM-ODP transparencies.

    • Hexagonal over layer

    • MVC II for reuse, maintain and infrastructures

    • Naming services / proxies

    • Application Server

    • Basic Interface to implement: (by all information worlds)

      • IsDataContained

      • IsDataValid

      • ReturnDataByIdentifiers


    Systems blueprint3
    Systems blueprint

    • When starting a system you need to define which Information worlds should be implemented by your system.

    • System wont access data directly, just by calling the right information world.

    • Using the development cycle as part of the governance.


    Infrastructure blueprint
    Infrastructure blueprint

    • DB / OODB

    • Message queuing/delivering

    • Morphology engine.

    • Storage Las/Nas

    • Backup

    • Instant messaging

    • Load balancing

    • Manage users and permissions – AD

    • Web servers


    Infrastructure blueprint1
    Infrastructure blueprint

    • Indexing/retrieval engine

    • GIS server

    • Extract knowledge from un-structural documents

    • Application servers

    • Names extraction engine

    • Switches, hubs, firewalls

    • EAI

    • Document management

    • Mail server



    Relations
    Relations

    • Do you know other enterprise architecture patterns?

    • What are the relations?


    The data centric enterprise an ea pattern
    Uses

    • At least two governmental bodies in Israel.

    • MIT (variation of )

    • Do you know others?


    Summary
    Summary

    • Defined pattern for data centric enterprises

    • No perfect match, but might save a lot of time

    • Changes and adaptations will be more then appreciated.
