The tech business has a voracious urge for food for the Subsequent Huge Factor. However typically, 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 motive 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 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 huge distinction between these graphs and RelationalAI’s underlying information retailer: using relational database tech and common SQL, versus super-normalized graph information 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. In actual fact, me made an argument at Snowflake Summit 25 final week that the relational mannequin and SQL are the perfect technological foundations for constructing a lot of the information infrastructure underlying in the present day’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 all the time wins, and it’s going to win once more right here,” Aref instructed BigDATAwire on the Moscone Heart final week. “I’m sufficiently old to recollect the 80s when folks have been like ‘These things isn’t 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. In actual fact, it’s the architectural basis for a lot of huge analytical databases, comparable to Snowflake. However you don’t hear folks differentiating between relational OLAP (or ROLAP) and MOLAP anymore, Aref mentioned. Right now, ROLAP principally 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 huge 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 easy methods 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 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 put money into Snowflake,” he mentioned. “It was going to be Hadoop. Hadoop was going to be the winner. Huge information was the brand new workload and the one option to do huge 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 aim is to produce information in the very best option to feed AI algorithms, which may then motive upon it and assist customers get solutions to powerful questions, comparable to “What’s going to gross sales be subsequent December of iPhones in New York Metropolis”? “That’s not 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 shoppers’ structured, semi-structured, and unstructured information. That primarily permits the AI mannequin to grasp relationships that exist in clients’ information.
“It’s a brand new form of information graph,” Aref mentioned. “It’s not a navigational graph. We’re completely different from graph as a result of we will motive predictively, prescriptively with guidelines and with the normal 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 mentioned.
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 help you do to mannequin graphs,” he mentioned. “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 buildings 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 shopper, significantly with regards to the safety and governance of knowledge. RelationalAI can also 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 prime of their information.
Aref mentioned he respects what earlier graph database builders constructed utilizing the instruments and applied sciences that have been out there on the time. However due to advances in computing, in the present day there’s no have to 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 folks,” Aref mentioned. “Our strategy I feel is somewhat bit extra humble. We have now extra humility. It’s like, hey, you’re on Snowflake. You’re in SQL. We all know easy methods to make it so that you could run relational queries which can be asking graphy questions.”
