WSS 3.0 v/s MOSS 2007
Some of the functionalities such as BI Delivery Platform, BDC and Portal are available only with MOSS 2007 and not with WSS 3.0. Therefore, the decision to use MOSS 2007 becomes very simple if an organization requires these features. WSS 3.0 on the other hand has a major set of features fine tuned for Collaboration and hence, it becomes difficult to choose between the two if Collaboration is the only requirement for the organization. A tenet that can be followed for the selection between the two is that for the organizations, which require Portal and Search capability across all the sites under the portal and even on Line of Business applications data, MOSS 2007 can be used to aggregate organize and present the information. However, for low (project) level sites i.e. sites lower in the organization, WSS 3.0 will suffice from the perspective of Collaboration.
Note: WSS 3.0 Search can index content only within the site and its sub-sites. There are certain other features as well, which are not available with WSS 3.0 like personal sites, news, and site directory.
