Migrating the Devonian Lithological Database to a Fully Relational System: The Story So Far

tmoore — Sat, 07 Aug 2010 19:07:12 +0000

The Devonian Lithological Database (DLD for short) is a database I published as part of my PhD work at the University of Arizona. As databases go, it was quite primitive but it got the job done. Over the past year or so, I've been migrating the database to a more modern SQL format using SQLite. SQLite is a public domain database designed to work without a server. It is easy to use (for a SQL database) and the data file is generally cross platform.

The migration from the original DLD format to the SQLite format has not been easy. DLD originally consisted of two basic tables: the data records and the source list. The data records were based in Microsoft Excel with 34 columns of information. The reference list was just a Endnote database. Inserting these tables into SQLite is actually quite easy. However, early on, issues made themselves apparent.

A Case for Spatially-Enabled Reference Databases

In my latest video, I try to make the case that spatially-enabled reference databases are very powerful tools. Thus, I show how such a reference database can be used to work with developing geological databases like the Devonian Lithological Database.

Here's the video:
