Data Catalog Requirements Assessment & Tool Selection

For the implementation of a data catalogue, requirements were recorded and a tool evaluation was carried out.

/
Requirements from stakeholder interviews result in 25 prioritised user stories

Approx. 40 developed and weighted tool evaluation criteria

N
Four potential Data Catalog tools evaluated
Decision for a data catalogue tool for the PoC phase

Challenge

  • A German car manufacturer wants to create transparency about its data objects and their relationship to each other and display them in a so-called data map.
  • The data is to be mapped in a data catalogue in order to also make it available more quickly and thus increase the usefulness of the data.

Solution

  • In order to capture the requirements of potential users of a data catalogue, interviews were conducted with about 15 stakeholders and their requirements were analysed on the basis of user stories and personas.
  • Subsequently, the collected requirements were evaluated and prioritised together with the stakeholders.
  • Furthermore, a shortlist of potential data catalogue tools was drawn up and a list of functional and non-functional evaluation criteria and their weighting was developed.
  • Based on the shortlist and the evaluation criteria, the Data Catalog tools were assessed as follows

Results

  • Stakeholder requirements were analysed in user stories and taken into account in the functional evaluation criteria
  • A total of four potential Data Catalog tools were examined and evaluated on the basis of 100 criteria
  • Selection of a data catalogue for testing within the framework of a proof of concept, possibly downstream PoC of a further tool.
