Data Governance
Les données d'une société sont aujourd'hui reconnues comme possédant une valeur au même titre que les revenus. Dans une société "Data Driven", la gestion de la donnée n'est plus laissée uniquement dans les mains du service informatique. Le Chief Data Officer - CDO - administre cette valeur à travers l'activité de Data Governance.
Contraste conseille les entreprises dans la mise en place d'une ou plusieurs étapes nécessaires à une bonne gouvernance des données. Notre objectif est notamment de définir les comités de contrôle, les rôles et responsabilités (data owner, data steward, ...), les policies ou les règles de contrôle externes (GDPR par exemple), les règles de sécurité et privacy ou encore de mettre en place une politique de change management.
Nos consultants techniques mettront en place des systèmes spécifiques visant à cette gouvernance de données optimale.
Data Quality
Good data governance obviously requires a data improvement phase. Carried out in part during the data integration phase, this often requires human interaction where automatic correction algorithms reveal their limits.
In order to manage the accuracy, completeness, consistency and deduplication of data, Contraste assists you in putting in place a strategy and carrying out various controls.
Contraste then supports you in developing architecture to correct data, but also to measure their quality on a regular basis.
Metadata and Data Catalog
If your company is large, you need a system that defines several key areas of each data item: data process and sources, responsibility chain, type of information, related constraints, confidentiality levels, etc.
We assist you in implementing this approach, including a referencing policy for these metadata. We draw up a business glossary with you to document business concepts and terminologies. The metadata will form the basis for data quality management and data governance.
Data catalog tools also update you automatically on the various elements to be taken into account (databases, ETL jobs, modelling tools, etc.) and assemble this information in a system intend for the CDO.
Reference Data
Some types of data, such as country codes and languages, are common to a company’s various applications. To put in place a real data governance system, benefit from business intelligence and the integration of applications, you need to gather the reference data in a single data source. This will enable you to manage the codification differences between applications.
Master Data Management (MDM)
Clients and product data are information that is spread across a large number of applications and databases within your company. Contraste assists you in establishing a centralised warehouse, called Master Data Management.
The development of an MDM system establishes the processes with a view to establishing a single data source. We therefore create a reliable source which centralises a data version of the highest possible quality.
