A common misconception is that phpLogCon requires a MySQL database in order to work. This is not true. First of all, no database at all is needed if phpLogCon is used in text file only mode. In that mode, it can display, search and analyze pure text files. The user db system, which stores user profiles, is not available for obvious reasons in this install mode.
The user db system currently requires MySQL, simply because there were so many votes who said it should support something else. However, the system is modeled in a way that should make it fairly easy to use another database system.
Data sources, however, can come from a variety of databases, including MySQL, Oracle, Postgres and a variety of other database systems. The driver for these systems need to be specified in the data source definition.
