Changes to Power BI’s Publish to Web

Boniface Muchendu looks at some changes:

In this guide, you’ll learn what “Publish to Web” does, how Microsoft updated it for better governance, and how to manage access responsibly.

The Costs of Implicit Conversion

Andy Brownsword changes things around:

Implicit conversion happens in SQL Server when the engine detects a mismatch in data types and automatically converts from one type to another. This can be helpful as it makes different types interchangeable and is generally transparent to the client, but it can come with issues.

Usually the downside from implicit conversion is seen through performance impact. But we’ve got something a little different today – an inconsistent result set.

Read on for Andy’s example.

Customer Managed Keys in OneLake

Harmeet Gill shows us how we can bring our own keys to data in OneLake:

One of the highly requested features in Microsoft Fabric is now available: the ability to encrypt data in OneLake using your own keys. As organizations face growing data volumes and tighter regulatory expectations, Customer-Managed Keys (CMK) offer a powerful way to enforce enterprise-grade security and ensure strict ownership of encryption keys and access.

With Microsoft’s OneLake, we’ve built a unified data lake that’s open, secure, and ready for enterprise scale. Now, with support for CMK, we’re giving customers the power to take encryption into their own hands.

Read on to learn more about Microsoft’s default for data encryption, and how you can use your own keys to encrypt the data.

Index Maintenance for Large Databases

Jon Russell shares some thoughts:

Most database administrators are comfortable with the daily tasks of backup, CHECKDB, index maintenance, and statistics updates. The available guidance for those topics is extensive. Much less has been written about caring for estates that contain hundreds of databases—or a single database large enough to strain conventional maintenance windows. This post will focus on options that help when individual tables or complete databases grow beyond the point where “standard” maintenance jobs finish in a reasonable time.

Click through for Jon’s advice. My big thing is to stop worrying and learn to love the bomb fragmentation. Index fragmentation was very important back in the days of spinning disk, where accessing pages took much longer if you needed to move the disk head. With NVMe storage, all-flash arrays, and even more prosaic solid state drives, random access is typically at least as fast as sequential access, so there’s no real benefit to having pages of data be contiguous.

Building Entity-Relationship Diagrams with DBeaver

Dave Stokes builds a diagram:

Even the most experienced database professionals are known to feel a little anxious when peering into an unfamiliar database. Hopefully, they inspect to see how the data is normalized and how the various tables are combined to answer complex queries.  Entity Relationship Maps (ERM) provide a visual overview of how tables are related and can document the structure of the data.

Choosing Fields to Hide in Power BI

Reza Rad has something up his sleeve:

To tidy up your Power BI solution, there are some options, and one of them is hiding fields from the report view. This option, although simple, has a significant impact on making your Power BI solution very tidy and clean and easier to maintain. However, you might wonder what are fields that have to be hidden in Power BI? In this article, I will explain how to hide a field in report view, and then what are fields which are a good candidate for this option. If you like to learn more about Power BI. Read Power BI book from Rookie to Rock Star.
