What is kwb.db?

A water-research lab's ODBC helper, still fighting Windows database drivers a decade in.

kwb.db is internal tooling from Kompetenzzentrum Wasser Berlin that wraps ODBC access to MS Access and similar databases for the lab's R workflows. Its functionality covers schema inspection, relation reading and database dumps, with a long-standing preoccupation with the 32-bit versus 64-bit driver split on Windows. The most recent release pins a newer RODBC to fix Windows installation.

What is rolap?

A star-schema modelling package grew a query language, a deployment path, and then a map layer.

rolap builds dimensional models — star databases and constellations — from flat tables inside R. Over 2023 it acquired a multidimensional query interface, the ability to deploy models into relational databases, incremental refresh, and geographic layers exportable as GeoPackage. Since early 2024 it has been quiet, with the only 2025 release removing a test that clashed with another package.

kwb.db vs rolap: editorial side-by-side

A water-research lab's ODBC helper, still fighting Windows database drivers a decade in.

◆ Current state

kwb.db is internal tooling from Kompetenzzentrum Wasser Berlin that wraps ODBC access to MS Access and similar databases for the lab's R workflows. Its functionality covers schema inspection, relation reading and database dumps, with a long-standing preoccupation with the 32-bit versus 64-bit driver split on Windows. The most recent release pins a newer RODBC to fix Windows installation.

◆ Where it's heading

The visible history is dominated by driver plumbing rather than features. Early versions added a bridge for calling 32-bit ODBC drivers from a 64-bit R session, then reversed course once 64-bit drivers shipped with MS Office, preferring RODBC directly and falling back only when needed. Later work exposed more of the internals — dumpDatabase, SQL builders, then schema and relation readers — turning a connection helper into something closer to a metadata extractor. The 2025 release is pure survival, and its note candidly records that Ubuntu and macOS installs still fail in CI.

◆ Prediction

Expect the next release to respond to another RODBC or driver breakage rather than to add functionality, given that installation has been the binding problem across the last several releases.

A star-schema modelling package grew a query language, a deployment path, and then a map layer.

◆ Current state

rolap builds dimensional models — star databases and constellations — from flat tables inside R. Over 2023 it acquired a multidimensional query interface, the ability to deploy models into relational databases, incremental refresh, and geographic layers exportable as GeoPackage. Since early 2024 it has been quiet, with the only 2025 release removing a test that clashed with another package.

◆ Where it's heading

The 2023 releases trace a deliberate progression from modelling to operating: first a common data model and flat table class, then role-playing dimensions, then incremental refresh, then querying and deployment, then geography, then slowly changing dimensions. That is essentially the feature checklist of a data warehouse, assembled in about six months and documented with a vignette at each step. The pace since has dropped to almost nothing, which reads as a project that reached its intended scope rather than one that stalled.

◆ Prediction

Given eighteen months in which the only release was a test removal, the next release is more likely to be maintenance than another warehouse feature — though the entries give no clear signal either way.
