Domain specific software architecture comprises:

• A reference architecture, which describes a general computational framework for a significant domain of applications.
• A component library, which contains reusable chunks of domain expertise.
• An application configuration method for selecting and configuring components within the architectural to meet particular application requirements.

DSSAs involve a number of domain engineering activities. The regions of the problem space (domains) are mapped into domain-specific software architectures (DSSAs) which are specialized into application-specific architectures and then implemented.

The three key factors of DSSA are:

1. Domain: Must have a domain to constrain the problem space and focus development
2. Technology: Must have a variety of technological solutions like tools, patterns, architectures & styles, legacy systems to bring to bear on a domain
3. Business: Business goals motivate the use of DSSE Minimizing costs: reuse assets when possible Maximize market: develop many related applications for different kinds of end users

These three factors together apply technology to domain-specific goals which is made firm by business knowledge. The overview of the DSSA process is given below:
