Open-source web GIS development leads to new paths
Open-source software and the Internet go together "like bread and butter" might be true in the private world, but in public agencies, proprietary software is the dominant player. Web GISs in most public agencies, if they exist, typically are built on the backbone of enterprise database management systems such as Oracle or Microsoft SQL Server. The Santa Clara Valley Transportation Authority developed a Web GIS based on a PostgreSQL open-source relational DBMS as the backend.
