Big Data: We're Not There Yet - Part II

In an attempt to show one of our customers a better way to connect a legacy Postgres system to a large data set, a team of AE experts turned the discussion into an internal competition. Contenders Phoenix and Cassandra already lost the challenge, as you can read in Part I.  In Part II we'll explore whether Drill or Impala can rise to the occasion.

Big Data: We're Not There Yet - Part I

Recently, one of our customers introduced an old-fashioned data solution: an error-prone ETL-flow coded in C to move flat files to Postgres. We wanted to demonstrate how this could be done with technologies such as Drill, Cassandra, Phoenix, Impala, ... The constraint we have to cope with is that the data ultimately should be consumable by Postgres using a Foreign Data Wrapper.

Piece of cake, right? Wrong!

Innovation in data governance: ETL visualization using graph databases

During a recent project innovation sprint at a customer, we decided to tackle our customer’s data warehouse documentation problem. It was hard to get proper insight in the data streams at hand due to various data sources, changing standards and legacy code. Take for example a random field: in which reports is it being used, to which source can it be tracked, which transformations have been applied, etc?

Since our aim was to thoroughly reshape the infrastructure, we decided to add this kind of information because it would allow us to better gauge the impact of our modifications. During the innovation sprint, we developed a system that builds said info and makes it possible to query.

New rules fit for a digital era: What to expect from the New EU Data Protection Regulation

On April 14, 2016, the General Data Protection Regulation (EU 2016/679) was formally accepted by the European Parliament. In the summer of 2018, this new regulation will replace all national data protection laws and regulations.

Integrating applications: Bridge the gap with a functional specification

So you need to connect an application to an external system. Developers and IT architects know how to cover the technical side, with for example SOAP web services, REST APIs, or stored procedures. But there is more to integration than just a choice in technology. You also face a functional challenge: the relevant functionalities of multiple applications must seamlessly fit into each other.
