Q&A

What exactly is a “Framework”?

A set of ideas, principles, agreements, or rules that provides the basis or outline for something intended to be more fully developed at a later stage (e.g. - providing a framework for next week's discussions)

A Software Framework is a re-usable design for a software system (or subsystem). A software framework may include support programs, code libraries, a scripting language, or other software to help develop and glue together the different components of a software project. Various parts of the framework may be exposed through an Application Programming Interface (API). [from Wikipedia]

What exactly is an “Architecture”?

Architecture is the activity of designing and constructing buildings and other physical structures by a person or a machine, primarily to provide socially purposeful shelter. [From Wikipedia]

From a software perspective, an Architecture is a design (or “blueprint”) of an application system, which may leverage one or more Frameworks. An Enterprise Architecture is an even higher level design that attempts to encompass multiple application system under a common overall design.

What comes first? Architecture or Framework(s)?

May depend on maturity of current organization:

• Do Frameworks already exist?

• Is a Partial or Full Architecture in place today?

• Are application building blocks in use today?

Architecture can be created without Frameworks in existence. However, the existence of well defined Frameworks can greatly enhance and simplify architecture and design.

Architecture can identify and drive the need for Frameworks. Therefore, it may be appropriate to develop and evolve

Architecture and Frameworks in parallel.

Why create and leverage Frameworks?

Simplifies common programming tasks (provide high level building blocks that programmers can leverage).

Enforces consistency and standards. All developers call the same framework API for application services.

May insulate applications from many changes that can be encompassed at the Framework level instead.

What types of functions may be best placed in Frameworks?

Caching Events (special handling) Security

Codes Exception Handling Session/State

Collections Globalization Storage Virtualization

Data Access Messaging Threading

Data and Work Flow Object Pooling Utilities

Diagnostics/Logging Remoting Transaction Demarcation

Doc. Management Resource Allocation Web Services

…and much more!

Driving Effective Architecture -Some best practices

Business Goals:

Maintain focus on the business

Use well-known patterns

Deliver “value-up” in small, rapid iterations

Value Up

User Goals:

Stay focused on users—ultimately they decide the fate of any IT project.

Intensify customer connected engineering Customer Advisory Board, Stories / Scenarios, Prioritization, Feedback (continuous communication)

Grow trust & build relationships

Constantly amaze! (set user expectation)

Technology Goals:

System performance depends on how parts interact, not on how they work separately

Taking a holistic approach can be more effective than addressing each subsystem individually
