BIG DATA ENGINEERING FOR ADVANCED
THE CHALLENGE
Our client, a US-based HR portal, had multiple data sources and data platforms – their existing ‘query and reporting’ systems were not able to give them an integrated view of the business, much less run useful analytics.
They approached Tatras to help them undertake a technology transformation which would enable advanced analytic outputs.
THE SOLUTION
Tatras examined multiple data sources, such as- Document data: which was textual and humongous
- Transactional data: coming from their OLTP system
- Subscription and Registration data
- Events data
- Ingested data from the OLTP and brought it into Hadoop including real-time pipelines using Storm and Spark realtime API
- Incremental updates to data tables using reconciliation views
- Exporting data to Visualisation tools
