The Importance of a Semantic Layer for AI & BI
November 2021
Sponsored by AtScale
This paper explains the importance of a semantic layer, provides key lessons for successful implementations, and outlines a relatable business scenario at a fictional company called ‘BIG Supplies’.
As data volumes grow, and as information is put to an increasing number and variety of uses, defining and maintaining a record of its diverse contexts and meanings is vital.
Data catalogs have already become common sight. The semantic layer is the next frontier in placing information with active context and meaning at the fingertips of businesspeople and automating the delivery of well-managed and performant data by IT.
Rethinking Hadoop for Modern Analytics
January 2020
Sponsored by Teradata
Since its initial rise in 2008, Hadoop and its yellow elephant logo have become ubiquitous in the data world and are largely synonymous with the concept and implementation of big data. Both terms—Hadoop and big data—have been so used and abused in marketing by vendors and consultants alike that their real meanings have been confused and obscured.
In the past year or two, Hadoop has fallen somewhat out of favor, experiencing a set of midlife crises: of identity, confidence, deployment, cloudiness, and data governance. This series of five ThoughtPoints, published from October 2019 to January 2020, explores Hadoop’s strengths and weaknesses, and what we should do about them as we enter a new decade when analytics has become a central aspect of digital transformation.
We conclude that Hadoop is not yet dead, but that in significant aspects of its current use, enterprises would be well advised to revisit relational technology as a foundation for improved data and systems management, and as a single access point for analytics distributed among multiple technologies and across a hybrid on-premises and cloud delivery environment. Teradata VantageTM with Advanced SQL is offered as a sound foundation for such an approach.
