Oracle Big Data SQL: 5 Key Points
Oracle announced last week that it will open up access to Hadoop and NoSQL data with Oracle Big Data SQL, a feature to be added to the Oracle Big Data Appliance in the third quarter. The new tool has some limitations, as this article describes, but the good news is that it will enable Oracle Database shops to take better advantage of big data using existing skills and expertise.
We were on the right track last week when compared Oracle Big Data SQL to Teradata Query Grid and Microsoft PolyBase. All three technologies are about SQL querying across databases and big data platforms, and all three ultimately move data to the vendor’s respective SQL database. There are differences under the hood that will make a difference for Oracle customers. We’ll get to these nuances in a moment, but what’s encouraging is that Oracle is not presenting this SQL tool like a hammer and all big-data-analysis challenges like nails. The idea is simply to enable SQL-trained professionals to do as much as possible with information from Hadoop and NoSQL sources from the familiar environs of Oracle Database.
