Application concepts are represented as tables with their attributes stored as table columns. This direct approach works well for applications with fixed structure. However, it fails for applications with structure that is not fully known as the application is being built. […]

Artificial Intelligence vs. Human Intelligence: Hey Robo Data Modeler!

Click to learn more about author Thomas Frisendal. In the data space plenty of new terms are being coined (by marketing?) for handling data modeling, governance and quality issues: “data preparation”, “data wrangling”, “data catalogue” and “machine-based data harmonization” (™ of ClearStory Data). Do we need stuff like this? Definitely so. Today we need to move […]

Debugging Complex SQL Queries

Developers can save time, effort, and reduce mistakes by substituting SQL for programming code. This leads to lengthy and complex SQL that must be debugged. It is common to write a SQL query that initially fails to execute. […]
