Building a Data Lake in the Cloud 

Hey fellow data warriors! Here is a new joint blog post I just did with fellow data warrior Dale Anderson from Talend! Check it out. I hope you find the concept compelling!

So you want to build a Data Lake?  Ok, sure let’s talk about that.  Perhaps you think a Data Lake will eliminate the need for a Data Warehouse and all your business users will merely lure business analytics from it easily.  Maybe you think putting everything into Big Data technologies like Hadoop will resolve all your data challenges and deliver fast data processing with Spark delivering cool Machine Learning insights that magically give you a competitive edge.  And really, with NoSQL, nobody needs a data model anymore, right?

Avoid the data swamp! Use modern cloud based DWaaS (Snowflake) and the leading-edge Data Integration tool (Talend) to build a Governed Data Lake.

Read the rest: How to Build a Governed Data Lake in the Cloud with Snowflake and Talend

Enjoy!

RI (Referential Integrity) Constraints: 3 Reasons to Include Them in Your Data Warehouse

Over the years, I have had numerous conversations about the value of having referential integrity (RI) constraints, such as primary and foreign keys, in a relational data warehouse or data mart.

Many DBAs object that RI constraints slow the load process. This is a valid point if you are talking about enforced constraints that are checked in real-time during the load. But this is not an issue if you define the constraints as disabled.

Which then leads to this common question:

Is there any reason to maintain a permanently disabled FK in the data model?  If it is not going to be enabled, then from my perspective, it doesn’t make any sense to define the FK.  Instead, the relationship can be described in the comment of the child column.

So, why would I want RI constraints in my data warehouse?

Here are 3 reasons to consider…RI (Referential Integrity) Constraints: 3 Reasons to Include Them in Your Data Warehouse

Model on!
