This week’s edition of my @linkedin newsletter shines a light on the impact of the Model Context Protocol (MCP) across multiple computing eras—leading right up to today.
We’ve arrived at a moment where loose coupling principles are cool (and super useful) again.
Naturally, there are some live demo nuggets in the post to help bring it all to life:

The Model Context Protocol acts as a universal translator between LLMs and data sources, eliminating complex platform-specific requirements. Our new open source MCP server for ODBC (mcp-odbc-server) enables seamless integration of any ODBC-accessible data into RAG pipelines.

Ok, a question for #database #dbms nerds. Many years ago I worked on a join order optimizer that used a heuristic formula to estimate the number of rows produced by an equijoin, based on the number of rows in the two tables being joined and the number of distinct values in the join keys. This formula came from an academic paper, but I can't remember what the formula was or find the paper. Does this ring a bell for anyone? Boosts appreciated...
“If you can think it, you can link it!” — from a podcast generated by AI Agents via @Google’s #NotebookLM using my notes to explore how hyperlinks can bust data silos, especially useful in the age of #GenAI.

For years, we’ve offered a personal #DataSpaces platform providing an abstraction layer over data managed by #filesystems (including cloud services) and/or #DBMS.
You can even mount #Dropbox, #OneDrive, #S3, etc., with fine-grained access controls for governance.
In the age of #AI, we’re making this usable via natural language as an extension (e.g., #CustomGPT) for #LLM-based chatbots like #ChatGPT.
RIP #MariaDB ?

Was mir jetzt spontan als Info im Artikel gefehlt hat:
* Läuft #Dolibarr in einer Feld-Wald-und-Wiesen-#LAMP-Umgebung? Wie ich das sehe, offenbar ja... #PHP 7.1-8.2 und #DBMS #MariaDB, #MySQL oder #PostgreSQL.
* Wie steht es um das Thema #XRechnung?
Da bin ich bisher noch nicht fündig geworden...

Und der Unterschied dolibarr.de und dolibarr.org ist mir auch noch nicht ganz ersichtlich... ;-)

Woot!
Another wonderful release of our modern multi-model #DBMS for operating on relational tables and entity relationship graphs.
BTW -- #ChatGPT, courtesy of its underlying #LLM and #ConversationalUI, is a great companion for utilizing this unique platform -- as recent posts demonstrate.
We are pleased to announce immediate availability of a new maintenance release of our #VirtuosoRDBMS (commercial edition).

#SPASQL is how our #VirtuosoRDBMS enables declarative operations on data organized as tables or graphs via #SPARQL inside #SQL.
What are the benefits?
[1] Ubiquitous Data Source Names (#DSNs), courtesy of #HTTP
[2] Fine-grained entity relationship graph comprising clickable edges and nodes that function as #SuperKeys
#ChatGPT knows SPASQL too!
#ChatGPT is a powerful tool for acquiring new skills productively while also reinforcing what exists.
In a new post, I provide a ChatGPT transcript comprising prompts that generate #SQL and #SPARQL #Cheatsheets enhanced using hyperlinks.
