Who are we?

Anyone who has worked for a while in the rapidly changing data warehouse industry knows how hard it is to keep up.

When you can’t get the answers from existing data solutions, sometimes you have to create your own.

That’s why it helps to have a veteran of the industry on your team.

Uli Bethke is the founder and CEO of Sonra. He has implemented dozens of data warehouses across four continents, ranging from small data marts to large scale enterprises with multi-million-dollar budgets.

Uli is the author of several books on data integration and a regular speaker at international conferences. He is also a VP and the co-founder of DAMA Ireland, the Irish branch of DAMA International.

As well as assembling an expert team of data management advisors to work with organisations around the world, Uli is an innovator.

At Sonra, we have developed an industry-leading data conversion tool in Flexter.

You did in one day what we could not achieve in three years!

Aer Lingus

As the second biggest airline in Ireland, with over 10 million passengers annually, Aer Lingus must process enormous amounts of data.

The main issue was the nightly loading of booking data, which a project outsourced to a third party had failed to solve after 50 days.

We implemented Flexter to handle this. It required no custom development and was up and running within a day.

Key results:


  • Eliminated project risk – Aer Lingus knew immediately that our solution worked.
  • A dramatic cut in costs of XML ingestion – 120 man-days and the ongoing cost for code maintenance were eliminated.
  • Meeting SLAs – Flexter performed orders of magnitude better than the previous aborted attempt, helping Aer Lingus meet SLAs.
