Abstract [en]

In order for a well functioning data warehouse to succeed many components must work together. Metadata, usually called data about data, is an important part. A more detailed description is that metadata is a documentation, description and explanation about the contents of the data warehouse. Metadata is supposed to be a helping hand to all co-workers in an organization that work directly or indirectly with the data warehouse. The main purpose of this research is to determine through feedback from the business end users and the other knowledge workers (like data base administrators), if metadata is needed for achieving the data quality, and hence the role of metadata in the data warehousing environment. To answer that question a qualitative survey has been carried out. Two different types of employees from two organizations have been interviewed. The conclusion is – Data quality indicators like data accuracy, data timeliness are well managed if the metadata is well defined or improved, so proper management of metadata can have the positive impact on the data quality. As the most end users are not much aware of the concepts of the metadata even though they are using the related tools, organizations make them learn by creating interest in them.
