Web Services Implementation GuideVolume 1: Getting Started


5

Systems Analyst

• Understand the business• Design systems• Break it down into pieces• COBOL


6

Flash Forward...

• 30 years later• Mainframes still around• Diversity rules• Departments not held hostage


7

Loss of Discipline

• Small systems proliferate• Many different programming languages• Single-programmer systems• Unchecked development and

deployment• Interoperability not possible

• Or even necessary


8

Modern Systems

• Applications have become• more critical to the organization• more complex in design and implementation• more diverse in language choice

• Lack of discipline makes integration very difficult


9

Then Came XML

• Standard for sharing data• Across organizational, departmental,

application boundaries• Application integration possible

• Now there's a way...... is there a will?


10

Systems Analyst Revisited

• Systems analyst no longer good enough• Job description includes

• Knowledge of current systems• Understanding of business processes• Ability to communicate to all parties• Knowledge of resources and possibilities


11

Meet the Architect

• More than just an analyst• More than a project manager• More than a DBA or programmer

• Several layers...

14

Help!

• So many languages• So many platforms• So many requirements• So much complexity• So much interoperability

• The Architect needs help


15

Visual Studio.NET Enterprise Architect Edition

• Many languages supported• Many platforms supported• Many tools for interoperability

• Brings discipline back to system design and implementation


16

Project Development Phases

• Architecture• Design• Implementation• Deployment and Operations


17

Integration with other tools

• Visio for design and UML modeling• SQL Server for database design• SourceSafe for version control• Windows Management Instrumentation

(WMI)• Application Center Test (ACT)• Microsoft Operations Manager (MOM)


18

Bringing Discipline Back

• Policies and Templates• Enterprise Template (ETP)• Template Design Language (TDL)• Restricts programmers bases on project policy

• .NET Framework• Single model for run-time operations• Pointer management• Single set of objects• Multi-language support

• Working Together• Large teams• Version control• XML Web services interoperability

Service-Oriented Architecture

Encapsulating Business Processes


23

Evolution of Architectures

• Process-Oriented Architecture• Uses processes to act on data• Requires that the system have intimate knowledge

of the process details in order to interface with them• Data is accessed and manipulated by these

processes, which can lead to corruption of the data and can compromise security.

• Service-Oriented Architecture• Encapsulates processes and data• Exposes processes and data together as a

homogenized service• Can be utilized where necessary while keeping the

data isolated, secure, and centrally managed
