This release is another important step towards stability. Several bugs have been fixed and new features have been introduced at all the different levels of the Web usage mining process. A key point is the introduction of a multi-level summarisation framework in the custom data warehouse. This architecture allows the use of a summary navigation system (typical of data warehouses). Support for PostgreSQL 8.2.x has been added. Although it cannot still be considered stable, this version is the best available so far. Its usage for production is recommended.
This release compiles on G++ 4.x. Doxygen generation was fixed and man pages and a tutorial page were added. The OLTP loader now features automatic index creation. A bug with XML file encoding in the Hierarchy Manager was fixed. The Warehouse loader now includes a Perl script that organizes OLTP data into the first stage warehouse. A '-U' option for updating the UNION views of the facts was added. The Custom Warehouse Framework now has days table management. Location management from the GeoIP library was added.
This release adds support for PostgreSQL Unix socket
connections. A multiple database approach has been
transformed into a single database/multiple schemas
approach, thanks to PostgreSQL's support of schemas.
PostgreSQL 7.x has been abandoned for active development
and support in favor of version 8.x. Tablespaces support
(PostgreSQL 8.x) has been added. Methods have been added
for querying the underlying PostgreSQL database system.
Options that perform administrative tasks such as schema
creation and (most importantly) tables and indexed creation
have been added. This release has a custom warehouse
concept.
