Architecture

 
The architecture of a software solution governs key system characteristics and features Overview - Article written by Frank Buschmann, CT
- How does my software solution behave under peak load conditions?
- Are permanent 24-hour operations feasible?
- Can the system be enhanced later on without problems?
These and many other so-called "non-functional" characteristics are especially important in e-business projects. They depend largely on the foundations the solution is based on, how the functionality is distributed over components, and how these components communicate with one another. And this is exactly what architecture is about.
 


Overview provided by SBS SYS (German)
Here, the SBS System Strategy unit provides a competent overview of application architectures for e-business and m-business solutions.
When must the architecture be defined?
The architecture must be planned as early as in the Definition phase and described in its basis principles in the "Planned architecture" document.
In this context, it is important to conceive the architecture as "proactively" as possible to ensure that it will be possible to implement later releases without a "break" in architecture, as far as possible.
All the requirements relevant for the solution's architecture should already be known in the Definition phase.

What steps need to be taken?
From the broad range of available system elements such as web and application servers, as well as technologies such as XSL and JSP, you have to select the components and solution approaches best suited for the current project. Supplementary information on this topic is provided under "Methods and templates".
The experts from the Architecture ExpertNet and from the PSE Support Centers will also be pleased to help you.
