The tech business has a voracious urge for food for the Subsequent Large Factor. However generally, it’s the older factor that finally ends up being the appropriate device for a brand new job. That’s the argument being made by RelationalAI founder and CEO Molham Aref, who sees no cause why relational databases can’t provide the graph relationships which are serving to to energy a brand new class of AI workloads.
RelationalAI develops a information graph base that’s designed to retailer and question linked knowledge in help of predictive and prescriptive AI-powered workloads. In that respect, it’s much like the underlying property graphs that retailer knowledge in nodes and edges, like Neo4j, and semantic graphs like AllegroGraph, which retailer knowledge in units of semantic triples.
Nonetheless, there’s one massive distinction between these graphs and RelationalAI’s underlying knowledge retailer: the usage of relational database tech and common SQL, versus super-normalized graph knowledge constructions and specialised question languages. Whereas the main property and semantic graphs use specialised tech, RelationalAI has constructed upon expertise that traces its roots within the 70s. That makes RelationalAI a little bit of an oddity in a hype-driven enterprise.
However Aref makes no apologies for his strategy. In actual fact, me made an argument at Snowflake Summit 25 final week that the relational mannequin and SQL are one of the best technological foundations for constructing a lot of the info infrastructure underlying at the moment’s generative AI and agentic AI purposes.
RelationaAI CEO and Founder Malham Aref
“I believe we should always all simply settle for that the relational mannequin at all times wins, and it’s going to win once more right here,” Aref advised BigDATAwire on the Moscone Middle final week. “I’m sufficiently old to recollect the 80s when individuals had been like ‘These things isn’t going to work for OLTP. Actual programmers need…flat recordsdata and navigational databases.’ And within the 90s it was MOLAP, multidimensional OLAP, is the one means and relational is silly.”
OLAP, or on-line analytical processing, remains to be round. In actual fact, it’s the architectural basis for a lot of massive analytical databases, similar to Snowflake. However you don’t hear individuals differentiating between relational OLAP (or ROLAP) and MOLAP anymore, Aref mentioned. At the moment, ROLAP mainly is synonymous with OLAP.
There have been many makes an attempt to greatest the relational mannequin and SQL through the years. The entire Hadoop part was one massive experiment in that. When it was a small startup, Snowflake garnered consideration by proudly proclaiming the effectivity and knowledge of utilizing the relational mannequin and SQL whereas the remainder of the world was determining methods to retailer knowledge on the Hadoop Distributed File System (HDFS) and use complicated frameworks like MapReduce to course of it. Makes an attempt to re-normalize the info, i.e. Apache Hive, resembled attempting to place Humpty Dumpty again collectively once more.
Aref remembers the problem that Snowflake confronted in these early days from a skeptical Sand Hill Street. He remembers former Snowflake CEO Bob Muglia telling him that Snowflake was rejected 27 occasions for a Sequence C funding spherical. That elucidated some chuckles from Aref as he recalled the spectacle.
“Think about being the investor that turned down a possibility to spend money on Snowflake,” he mentioned. “It was going to be Hadoop. Hadoop was going to be the winner. Large knowledge was the brand new workload and the one strategy to do massive knowledge is MapReduce. ‘Look, Google is doing MapReduce. Relational is lifeless. Overlook about it.’ After which Snowflake got here up with a cloud-native structure and got here up with help for semi-structured knowledge, and now Hadoop is COBOL.”

Aref is combating an identical battle now with information graphs. As an alternative of shifting your knowledge right into a devoted property graph or semantic graph database, RelationalAI leaves it Snowflake tables and makes use of conventional SQL queries to ask graph-like questions, which can be utilized to feed predictive and prescriptive reasoners.
The purpose is to produce knowledge in the very best strategy to feed AI algorithms, which may then cause upon it and assist customers get solutions to robust questions, similar to “What is going to gross sales be subsequent December of iPhones in New York Metropolis”? “That isn’t a SQL query,” Aref mentioned. “It’s a query about one thing that hasn’t occurred but. It’s not within the database.”
RelationalAI goes past what’s doable with retrieval-augmented technology (RAG) by coaching and finetuning AI algorithms on its information graph utilizing the purchasers’ structured, semi-structured, and unstructured knowledge. That basically permits the AI mannequin to know relationships that exist in prospects’ knowledge.
“It’s a brand new sort of information graph,” Aref mentioned. “It’s not a navigational graph. We’re totally different from graph as a result of we will cause predictively, prescriptively with guidelines and with the normal graph powers.”
Simply as there are relational databases which are good at OLAP and relational databases which are good at OLTP (on-line transaction processing), we’re now seeing the emergence of relational databases which are good at graph workloads, Aref mentioned.
The RelationalAI structure
“Ultimately, a graph is only a connection between two issues. There’s nothing in regards to the relational mannequin that doesn’t mean you can do to mannequin graphs,” he mentioned. “The fantastic thing about the relational mannequin is it wasn’t like hardwired for only one workload. You are able to do OLTP and OLAP. It was hardwired to be an abstraction, and you may implement no matter knowledge constructions and be part of algorithms you need underneath the covers.”
RelationalAI deploys as a local app inside Snowflake’s platform, which brings sure benefits for the shopper, significantly in the case of the safety and governance of information. RelationalAI can be adopting the brand new semantic views that Snowflake unveiled at Summit, which is able to present extra standardization and make it simpler to construct predictive and reasoning utility on high of their knowledge.
Aref mentioned he respects what earlier graph database builders constructed utilizing the instruments and applied sciences that had been out there on the time. However due to advances in computing, at the moment there’s no must abandon the relational mannequin and SQL to construct information graphs, he mentioned.
“We’re not attempting to construct a cult. We’re attempting to construct one thing helpful for individuals,” Aref mentioned. “Our strategy I believe is a bit of bit extra humble. We now have extra humility. It’s like, hey, you’re on Snowflake. You might be in SQL. We all know methods to make it so that you could run relational queries which are asking graphy questions.”
