+# CWTS OpenAlex databases
+
+This repository contains the source code used by [CWTS](https://www.cwts.nl) to extract, transform, and load data from [OpenAlex](https://openalex.org) into a Microsoft SQL Server database system.
+
+The source code produces five Microsoft SQL Server databases:
+
+(1) Database containing data from OpenAlex in a relational format.
+
+(2) Database containing titles and abstracts of publications.
+
+(3) Database containing data on core publications.
+
+(4) Database containing a classification of publications into research areas.
+
+(5) Database containing stored procedures for indicator calculations.
+
+This repository makes use of the [CWTS ETL tooling repository](https://github.com/CWTSLeiden/CWTS-ETL-tooling), the [publicationclassification repository](https://github.com/CWTSLeiden/publicationclassification), and the [publicationclassificationlabeling repository](https://github.com/CWTSLeiden/publicationclassificationlabeling).
