Assembly Building Blocks
The assembly of a CRM application to meet your requirements in an optimal manner requires broad yet thorough knowledge of the available technology. Open source has produced some of the industry's leading technologies on the infrastructure level, such as operating systems (UNIX, Linux distros), web and application servers (JBoss/Jetty, Apache/PHP/Tomcat) and many more key components. Many companies are discovering that open source software already covers important areas of functionality that pertain to the CRM domain as well.
This paragraph introduces a collection of solution components relevant
for the CRM domain, and gives you a feel for where they're positioned
in terms of maturity, functionality, etc. These and other technologies
are reviewed in more detail in "Building Enterprise-Ready Open Source CRM" . We have divided up the landscape into logical sections (see also Figure 1: CRM functional overview).
