An Architecture for the IoT – Part 1

There are so many things in the Internet of Things (IoT) that might record data into your data fabric that a new approach may be required. Let’s think about this… define some terms, and see how these terms fit into current data fabric thinking, let’s consider how they fit into a more modern logical data warehouse…

Part 8 – How Hadooped is SQL Server PDW with Polybase?

Now for SQL Server… continuing the thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push down predicates; and Is…

Part 6: How Hadooped is HANA?

Now for HANA plus Hadoop… to continue this thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push…

Part 1: How Hadooped is Your RDBMS?

Sorry for the comic adjective “Hadooped”? The next few blogs will try to evaluate the different approaches to integrating Hadoop and a standard RDBMS… so the first thing I’ll try in this post is to suggest a criteria based on some architectural  choices for making the evaluation. Further, I’ll inject a little surprise and make…

The Hype of Big Data

As preface to this you might check out the definition I suggested for Big Data last week here… – Rob I left Greenplum in large part because they made their mark in… and then abandoned… the  data warehouse market for a series of big hype plays: first analytics and data science; then analytics, data science,…

The Big Data Devil

I just finished a draft for next week on Big Data and thought that with this note I might form a preface… First… Big Data is about, well…, Big Data. When Gartner devised the three V’s I suspect that they were trying to frame the new stuff that was emerging… not establish a concise definition.…

Hadoop and the EDW

Cloudera and Teradata have jointly published a nice paper here that presents an interesting perspective of how Hadoop and an EDW play together. Simply put, Hadoop becomes the staging area for “raw data streams” while the EDW stores data from “operational systems”. Hadoop then analyzes the raw data and shares the results with the EDW. Two…

Aster Data for a price…

If Greenplum HAWQ does not look promising (see my previous posts on HAWQ here and here) what are the prospects for Teradata Aster Data… which aspires to both replace and/or co-exist with Hadoop for a fee? Teradata+Hadoop maybe… but Teradata+Aster+Hadoop seems like one layer too many… as does Aster+Hadoop. (OK, I removed the bad “HAWQing” pun in the…
