Is hashing good enough for anonymising data?

If the hashing Algorithm is known, there is nearly no protection. Day of birth is about 100 (yrs) x 365 (days) values possible. Generating a 365k rows lookup table is a no-cost no-brainer. Same for city, zip code, social security number and more PII attributes. Or am I wrong with these assumptions?
What would you do if Data Vault would be forbidden?
Imagine a dystopian world, where you are not allowed to use Data Vault. How would you solve all the problems in your Data Warehouse?

I‘d take the red pill and start implementing DV in the underground.
Business vault hub?
Is a business vault hub a thing? We have a situation where the groups we want to report by are not in any source system but are rules applied to source data. Has anyone done one of these? pros? cons?

@Lorenz Kindling Absolutely correct. Business Object not driven by source systems are possible and to store in a BV Hub.

@Tim Kirschke Yes, generate hashkeys, don‘t change the patterns. For writing queries (optionally automized) it shouldn‘t be a difference to query RV or BV.
What Was Your First Experience Working with Data? Some Fantasy Football experts here?
Hey everyone, I'm curious to know—what was your entry point into the world of data? For me, it all began with Fantasy Football. I wanted to create my own stat analytics, so I started querying player databases using an API. There’s so much to analyze in American Football, and with our fantasy draft kicking off this Sunday, I’m reminded of those early days. So, what was your first data project? How did you get started? Looking forward to hearing your stories!

In 1983, with my Commodore 64, I coded a sequential database (state of the art in this time, this environment), to manage my Minitrix model railway‘s (9mm rail gauge) parts. It was giving me an overview about money spent in different categories (tracks, engines and coaches, landscape, buildings, …) and inventory. Later dealing with csv file, read by Microsoft Word for Windows 3 to automize spare part & service efforts for reports & invoices (mid of 90th). Continuing my data journey at Oracle‘s starting 2000 …
Database vs Data Warehouse vs Data Lake
This video from Alex the Analyst explains the differences between databases, data warehouses, and data lakes, which are fundamental concepts in data management. This is especially useful for beginners or those who are new to the field. For someone just starting out in the data management sector, or someone like me who is not from the field but wants to learn more about such terminology, do you have any additional tips or information about those terms? Leave them down below!

Database vs Data Warehouse vs Data Lake

Fifteen years ago, I would have thought that was a correct and good explanation (but data lake was not introduced as a common term). I'm now struggling with the definition of “data warehouse”, because in Data Vault we say “maintain the granularity of the source system” and “load the sources independently and auditably”. According to Alex Analyst Data Vault would not be a data warehouse. 🤣
