Semitag Customer Case - Micropole


To respond effectively to its main missions, which are the qualitative and quantitative development of the transport offer and the support of different modes of transport as alternatives to  private vehicles, SEMITAG has launched a data governance project and the creation of a decision-making platform to optimise its business analyses while constructing a cros-cutting  data repository.

The main challenges of this project were to support SEMITAG agents in researching and entering files in real time, identifying Grenoble's public transport customers and analysing their usage. The objective was to homogenise, centralise and cross-reference all this analysis data to better target future marketing actions.

With this in mind, and in order to provide a solution to these issues, MICROPOLE has assisted SEMITAG in :

  • The creation of a single customer repository to consolidate the 360° customer view, via quality management processes (MDM). This approach allows all business applications to benefit from data derived solely from this customer repository.
  • The definition of its future decision-support platform through a business-oriented approach
  • The design and implementation of all the interconnection and supply flows of the decision-making chain, up to the restitution bricks.

Methods and Solutions

During this project, a Data Hub-type architecture was considered and the Talend Data Services package was chosen.

Talend Data Integration, Talend Data Quality, and Talend Data Stewardship were used to consolidate all the data. The existing data was then recovered  and cleansed.

At the same time, inter-application flows were implemented using the Talend ESB tool to input and distribute data in real time.

A Back Office solution for the administration of reference data was implemented via the Adminify framework, an accelerator offered by Micropole.

Finally, the Front Office part was entirely realised via Angular web technology to offer a single input interface, regardless of the tool used (sales terminal, mobile application, website...).


This deployment enables SEMITAG to respond effectively to its issues:

  • The quality level of the reference data (the user) is known and controlled
  • At least 8 data sources (applications) consolidated into a single customer reference  base
  • Several million customer and address data corrected
  • Consolidation of users in a single, shared database (360° vision) facilitating exchanges with the various systems
  • GDPR restrictions are more easily applicable
  • Data analyses on transport usage is more reliable. 99% deduplicated data (and therefore more efficient data analysis via the usual reporting tools)
  • Better conversion rates for marketing campaigns

The strong partnership between Talend & Micropole efficiently and reliably guided this project in full compliance with   time and cost commitments.

Talend's suite of solutions addresses today's data issues, through common data quality problems (duplication, incompleteness, desynchronization, etc.). Micropole's expertise enabled us to make the best use of these tools and to interface successfully with our multiple applications and partners.
