CHANGES WE ARE MAKING FOR YOU

By Announcements No Comments
This month, our blog post will take a slightly different tone than our normal publications due to the current Covid-19 pandemic and its paralyzing effect on many areas of public life.

This said, we at Scalefree are reflecting on the ways we can do our part to  help contain the virus. Thus, the health of Scalefree’s customers, partners, employees, and the overall community is our highest priority. We do not want to subject any person to undue risk, and certainly those around us, who could be more seriously affected by the virus.

Due to this growing concern regarding the coronavirus (COVID-19), as well as in alignment with the best practices in addition to restrictions from local authorities, we have chosen to make our training programs fully available as live and interactive online classes.

Therefore, we would like to give you an overview of what changes Scalefree is making to help  stem the spread of Covid-19 while at the same time delivering actionable insights to our partners, customers and employees.

Delete and Change Handling Approaches in Data Vault 2.0 without a Trail

By Scalefree Newsletter 2 Comments
In January of this year, we published a piece detailing an approach to handle deletes and business key changes of relationships in Data Vault without having an audit trail in place.
This approach is an alternative to the Driving Key structure, which is part of the Data Vault standards and a valid solution.
Though, at times it may be difficult to find the business keys in a relationship which will never change and therefore be used as the anchor keys, Link Driving Key, when querying. The presented method inserts counter records for changed or deleted records, specifically for transactional data, and is a straightforward as well as pragmatic approach. However, the article caused a lot of questions, confusion and disagreements.
That being said, it is the intention of this blogpost to dive deeper into the technical implementation in which we could approve by employing it. Read More

Within a hybrid data warehouse architecture, as promoted in the Data Vault 2.0 Boot Camp training, a data lake is used as a replacement for a relational staging area. Thus, to take full advantage of this architecture, the data lake is best organized in a way that allows efficient access within a persistent staging area pattern and better data virtualization.

Data Vault Use Cases Beyond Classical Reporting: Part 2

By Scalefree Newsletter No Comments
As we first introduced within the first part of the Data Vault Use Cases article series, the Enterprise Data Warehouse (EDW) can do more than just simple reporting and dashboarding. 

We previously explored how the EDW can help to improve data quality by implementing data cleansing rules. 

This can be applied by write-back operations that affect the source systems directly. Though this was only one example of how to add more value to the EDW.
The scalability and flexibility of Data Vault 2.0 offers a whole variety of use cases that can be realized, e.g. to optimize and automate operational processes, predict the future, push data back to operational systems as a new input or trigger events outside the data warehouse, to name a few.
