It wasn’t so long ago that NoSQL products were considered competitors with relational databases (RDBMS). Well, for some workloads they still are. But Teradata is an analytic RDBMS which is quite different and complementary to MongoDB. Hence, we are teaming up for the benefit of mutual customers.
The collaboration of MongoDB with Teradata represents a virtuous cycle, a symbiotic exchange of value. This virtuous cycle starts when data is exported from MongoDB to Teradata’s Data Warehouse where it is analyzed and enriched, then sent back to MongoDB to be exploited further. Let me give an example.
An eCommerce retailer builds a website to sell clothing, toys, etc. They use MongoDB because of the flexibility to manage constantly changing web pages, product offers, and marketing campaigns. This front office application exports JSON data to the back-office data warehouse throughout the business day. Automated processes analyze the data and enrich it, calculating next best offers, buyer propensities, consumer profitability scores, inventory depletions, dynamic discounts, and fraud detection. Managers and data scientists also sift through sales results looking for trends and opportunities using dashboards, predictive analytics, visualization, and OLAP. Throughout the day, the data warehouse sends analysis results back to MongoDB where they are used to enhance the visitor experience and improve sales. Then we do it again. It’s a cycle with positive benefits for the front and back office.
Teradata Data Warehouses have been used in this scenario many times with telecommunications, banks, retailers, and other companies. But several things are different working with MongoDB in this scenario. First, MongoDB uses JSON data. This is crucial to frequently changing data formats where new fields are added on a daily basis. Historically, RDBMS’s did not support semi-structured JSON data. Furthermore, the process of changing a database schema to support frequently changing JSON formats took weeks to get through governance committees.
Nowadays, the Teradata Data Warehouse ingests native JSON and accesses it through simple SQL commands. Furthermore, once a field in a table is defined as JSON, the frequently changing JSON structures flow right into the data warehouse without spending weeks in governance committees. Cool! This is a necessary big step forward for the data warehouse. Teradata Data Warehouses can ingest and analyze JSON data easily using any BI tool or ETL tool our customers prefer.
Another difference is that MongoDB is a scale-out system, growing to tens or hundreds of server nodes in a cluster. Hmmm. Teradata systems are also scale-out systems. So how would you exchange data between Teradata Data Warehouse server nodes and MongoDB server nodes? The simple answer is to export JSON to flat files and import them to the other system. Mutual customers are already doing this. Can we do better than import/export? Can we add an interactive dynamic data exchange? Yes, and this is the near term goal of our partnership --connecting Teradata QueryGrid to MongoDB clusters.
Teradata QueryGrid is a capability in the data warehouse that allows a business user to issue requests via popular business intelligence tools such as SAS®, Tableau®, or MicroStrategy®. The user issues a query which runs inside the Teradata Data Warehouse. This query reaches across the network to the MongoDB cluster. JSON data is brought back, joined to relational tables, sorted, summarized, analyzed, and displayed to the business user. All of this is done exceptionally fast and completely invisible to the business user. It’s easy! We like easy.
QueryGrid can also be bi-directional, putting the results of an analysis back into the MongoDB server nodes. The two companies are working on hooking up Teradata QueryGrid right now and we expect to have the solution early in 2015.
The business benefit of connecting Teradata QueryGrid to MongoDB is that data can be exchanged in near real time. That is, a business user can run a query that exchanges data with MongoDB in seconds (or a few minutes if the data volume is huge). This means new promotions and pricing can be deployed from the data warehouse to MongoDB with a few mouse clicks. It means Marketing people can analyze consumer behavior on the retail website throughout the day, making adjustments to increase sales minutes later. And of course, applications with mobile phones, sensors, banking, telecommunications, healthcare and others will get value from this partnership too.
So why does the leading NoSQL vendor partner with the best in class analytic RDBMS? Because they are highly complementary solutions that together provide a virtuous cycle of value to each other. MongoDB and Teradata are already working together well in some sites. And soon we will do even better.
Come visit our Booth at MongoDB World and attend the session “The Top 5 Things to Know About Integrating MongoDB into Your Data Warehouse” Riverside Suite, 3:10 p.m., June 24. You can read more about the partnership between Teradata and MongoDB in this news release issued earlier today. Also, check out the MongoDB blog.
PS: The MongoDB people have been outstanding to work with on all levels. Kudos to Edouard, Max, Sandeep, Rebecca, and others. Great people!
