The tech business has a voracious urge for food for the Subsequent Massive Factor. However typically, it’s the older factor that finally ends up being the suitable 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 can 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 linked information in assist of predictive and prescriptive AI-powered workloads. In that respect, it’s just 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.
Nevertheless, there’s one large distinction between these graphs and RelationalAI’s underlying information retailer: using 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 strategy. The truth is, 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 as we speak’s generative AI and agentic AI functions.
RelationaAI CEO and Founder Malham Aref
“I believe we must 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 items is rarely going to work for OLTP. Actual programmers need…flat information 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, continues to be round. The truth is, it’s the architectural basis for a lot of large analytical databases, equivalent to Snowflake. However you don’t hear individuals differentiating between relational OLAP (or ROLAP) and MOLAP anymore, Aref stated. At this time, ROLAP principally is synonymous with OLAP.
There have been many makes an attempt to finest the relational mannequin and SQL over time. The entire Hadoop part was one large 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 find out how 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 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 Highway. He remembers former Snowflake CEO Bob Muglia telling him that Snowflake was rejected 27 instances for a Collection C funding spherical. That elucidated some chuckles from Aref as he recalled the spectacle.
“Think about being the investor that turned down a chance 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 method to do large 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 the same battle now with information graphs. As an alternative of transferring 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 aim is to produce information in the absolute best method 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 doable with retrieval-augmented era (RAG) by coaching and finetuning AI algorithms on its information graph utilizing the purchasers’ structured, semi-structured, and unstructured information. That primarily permits the AI mannequin to know relationships that exist in prospects’ information.
“It’s a brand new sort of information graph,” Aref stated. “It’s not a navigational graph. We’re completely 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 can be good at OLAP and relational databases which can be good at OLTP (on-line transaction processing), we’re now seeing the emergence of relational databases which can 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 great 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 information constructions and be part of algorithms you need beneath 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 knowledge. RelationalAI can also 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 high of their information.
Aref stated he respects what earlier graph database builders constructed utilizing the instruments and applied sciences that had been out there on the time. However because of advances in computing, as we speak there’s no have to abandon the relational mannequin and SQL to construct information graphs, he stated.
“We’re not attempting to construct a cult. We’re attempting to construct one thing helpful for individuals,” Aref stated. “Our strategy I believe is slightly bit extra humble. We have now extra humility. It’s like, hey, you’re on Snowflake. You might be in SQL. We all know find out how to make it in an effort to run relational queries which can be asking graphy questions.”
