The tech trade has a voracious urge for food for the Subsequent Massive Factor. However generally, it’s the older factor that finally ends up being the correct software 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 might be serving to to energy a brand new class of AI workloads.
RelationalAI develops a information graph base that’s designed to retailer and question related information in assist of predictive and prescriptive AI-powered workloads. In that respect, it’s much like the underlying property graphs that retailer information in nodes and edges, like Neo4j, and semantic graphs like AllegroGraph, which retailer information in units of semantic triples.
Nonetheless, there’s one massive distinction between these graphs and RelationalAI’s underlying information retailer: the usage of relational database tech and common SQL, versus super-normalized graph information constructions and specialised question languages. Whereas the main property and semantic graphs use specialised tech, RelationalAI has constructed upon know-how 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 method. The truth is, me made an argument at Snowflake Summit 25 final week that the relational mannequin and SQL are the most effective technological foundations for constructing a lot of the information infrastructure underlying at the moment’s generative AI and agentic AI purposes.
RelationaAI CEO and Founder Malham Aref
“I feel 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 Heart final week. “I’m sufficiently old to recollect the 80s when individuals had been like ‘These items is rarely 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 approach and relational is silly.”
OLAP, or on-line analytical processing, remains to be round. The truth is, it’s the architectural basis for a lot of massive analytical databases, equivalent to Snowflake. However you don’t hear individuals differentiating between relational OLAP (or ROLAP) and MOLAP anymore, Aref stated. At the moment, ROLAP mainly is synonymous with OLAP.
There have been many makes an attempt to finest the relational mannequin and SQL through the years. The entire Hadoop section 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 the way to retailer information on the Hadoop Distributed File System (HDFS) and use complicated frameworks like MapReduce to course of it. Makes an attempt to re-normalize the information, i.e. Apache Hive, resembled making an attempt 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 stated. “It was going to be Hadoop. Hadoop was going to be the winner. Massive information was the brand new workload and the one technique to do massive information is MapReduce. ‘Look, Google is doing MapReduce. Relational is lifeless. Neglect about it.’ After which Snowflake got here up with a cloud-native structure and got here up with assist for semi-structured information, and now Hadoop is COBOL.”

Aref is combating an identical battle now with information graphs. As an alternative of shifting your information 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 objective is to provide information in the absolute best technique to feed AI algorithms, which might then cause upon it and assist customers get solutions to robust questions, equivalent to “What’s going to gross sales be subsequent December of iPhones in New York Metropolis”? “That isn’t a SQL query,” Aref stated. “It’s a query about one thing that hasn’t occurred but. It’s not within the database.”
RelationalAI goes past what’s potential with retrieval-augmented era (RAG) by coaching and finetuning AI algorithms on its information graph utilizing the shoppers’ structured, semi-structured, and unstructured information. That basically permits the AI mannequin to grasp relationships that exist in clients’ information.
“It’s a brand new form of information graph,” Aref stated. “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 standard graph powers.”
Simply as there are relational databases which might be good at OLAP and relational databases which might be good at OLTP (on-line transaction processing), we’re now seeing the emergence of relational databases which might be good at graph workloads, Aref stated.
The RelationalAI structure
“In the long run, a graph is only a connection between two issues. There’s nothing concerning the relational mannequin that doesn’t can help you do to mannequin graphs,” he stated. “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’ll implement no matter information constructions and be a part of algorithms you need below the covers.”
RelationalAI deploys as a local app inside Snowflake’s platform, which brings sure benefits for the client, notably in the case of the safety and governance of knowledge. RelationalAI can be adopting the brand new semantic views that Snowflake unveiled at Summit, which can present extra standardization and make it simpler to construct predictive and reasoning utility on prime of their information.
Aref stated he respects what earlier graph database builders constructed utilizing the instruments and applied sciences that had been obtainable on the time. However due to advances in computing, at the moment there’s no have to abandon the relational mannequin and SQL to construct information graphs, he stated.
“We’re not making an attempt to construct a cult. We’re making an attempt to construct one thing helpful for individuals,” Aref stated. “Our method I feel is just a little bit extra humble. We have now extra humility. It’s like, hey, you’re on Snowflake. You might be in SQL. We all know the way to make it to be able to run relational queries which might be asking graphy questions.”
