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 fitting software for a brand new job. That’s the argument being made by RelationalAI founder and CEO Molham Aref, who sees no motive 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 just 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 large distinction between these graphs and RelationalAI’s underlying knowledge retailer: the usage of relational database tech and common SQL, versus super-normalized graph knowledge buildings 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. The truth is, me made an argument at Snowflake Summit 25 final week that the relational mannequin and SQL are the very 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 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 informed BigDATAwire on the Moscone Middle final week. “I’m sufficiently old to recollect the 80s when folks have been like ‘These things 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 method 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, resembling Snowflake. However you don’t hear folks differentiating between relational OLAP (or ROLAP) and MOLAP anymore, Aref stated. In the present day, ROLAP principally 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 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 tips on how 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 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 Highway. 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 put money into Snowflake,” he stated. “It was going to be Hadoop. Hadoop was going to be the winner. Massive knowledge was the brand new workload and the one method to do large knowledge is MapReduce. ‘Look, Google is doing MapReduce. Relational is useless. 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 the same battle now with information graphs. As an alternative of transferring 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 aim is to provide knowledge in the very best method to feed AI algorithms, which may then motive upon it and assist customers get solutions to powerful questions, resembling “What is 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 purchasers’ structured, semi-structured, and unstructured knowledge. That basically permits the AI mannequin to grasp relationships that exist in clients’ knowledge.
“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 are able to motive predictively, prescriptively with guidelines and with the standard 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 stated.
The RelationalAI structure
“Ultimately, a graph is only a connection between two issues. There’s nothing concerning the relational mannequin that doesn’t will let 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’ll implement no matter knowledge buildings 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, notably in terms of the safety and governance of knowledge. 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 stated he respects what earlier graph database builders constructed utilizing the instruments and applied sciences that have been obtainable 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 making an attempt to construct a cult. We’re making an attempt to construct one thing helpful for folks,” Aref stated. “Our strategy I feel is just a little bit extra humble. We’ve extra humility. It’s like, hey, you’re on Snowflake. You might be in SQL. We all know tips on how to make it with the intention to run relational queries which are asking graphy questions.”
