Issues in regulatory compliance

From time to time, I hear of regulatory requirements to retain, analyze, and/or protect data in various ways. It’s hard to get a comprehensive picture of these, as they vary both by industry and jurisdiction; so I generally let such compliance issues slide. Still, perhaps I should use one post to pull together what is surely a very partial list.

Most such compliance requirements have one of two emphases: Either you need to keep your customers’ data safe against misuse, or else you’re supposed to supply information to government authorities. From a data management and analysis standpoint, the former area mainly boils down to:

The latter, however, has numerous aspects.

First, there are many purposes for the data retention and analysis, including but by no means limited to: Read more

Clarifying SAND’s customer metrics, positioning and technical story

Talking with my clients at SAND can be confusing. That said:

A few months ago, I wrote:

SAND Technology reported >600 total customers, including >100 direct.

Upon talking with the company, I need to revise that figure downward, from > 600 to 15.

Text data management, Part 1: Confusion

This is Part 1 of a three post series. The posts cover:

  1. Confusion about text data management.
  2. Choices for text data management (general and short-request).
  3. Choices for text data management (analytic).

There’s much confusion about the management of text data, among technology users, vendors, and investors alike. Reasons seems to include:

Above all: The use cases for text data vary greatly, just as the use cases for simply-structured databases do.

There are probably fewer people now than there were six years ago who need to be told that text and relational database management are very different things. Other misconceptions, however, appear to be on the rise. Specific points that are commonly overlooked include: Read more

Teradata Columnar and Teradata 14 compression

Teradata is pre-announcing Teradata 14, for delivery by the end of this year, where by “Teradata 14” I mean the latest version of the DBMS that drives the classic Teradata product line. Teradata 14’s flagship feature is Teradata Columnar, a hybrid-columnar offering that follows in the footsteps of Greenplum (now part of EMC) and Aster Data (now part of Teradata).

The basic idea of Teradata Columnar is:

Eight kinds of analytic database (Part 2)

In Part 1 of this two-part series, I outlined four variants on the traditional enterprise data warehouse/data mart dichotomy, and suggested what kinds of DBMS products you might use for each. In Part 2 I’ll cover four more kinds of analytic database — even newer, for the most part, with a use case/product short list match that is even less clear.  Read more

Rainstor update

I was tired and cranky when I talked with my former clients at Rainstor (formerly Clearpace) yesterday, so our call was shorter than it otherwise might have been. Anyhow, there’s a new version called Rainstor 4, the two main themes of which are:

The point is that Rainstor is focusing its efforts on enterprises that:  Read more

I’ll be speaking in Washington, DC on May 6

My clients at Aster Data are putting on a sequence of conferences called “Big Data Summit(s)”, and wanted me to keynote one. I agreed to the one in Washington, DC, on May 6, on the condition that I would be allowed to start with the same liberty and privacy themes I started my New England Database Summit keynote with. Since I already knew Aster to be one of the multiple companies in this industry that is responsibly concerned about the liberty and privacy threats we’re all helping cause, I expected them to agree to that condition immediately, and indeed they did.

On a rough-draft basis, my talk concept is:

Implications of New Analytic Technology in four areas:

I haven’t done any work yet on the talk besides coming up with that snippet, and probably won’t until the week before I give it. Suggestions are welcome.

If anybody actually has a link to a clear discussion of legislative and regulatory data retention requirements, that would be cool. I know they’ve exploded, but I don’t  have the details.

Boston Big Data Summit keynote outline

Last month, Bob Zurek asked me to give a talk on “Big Data”, where “big” is anything from a few terabytes on up, then moderate a panel on cloud computing. We agreed that I could talk just from notes, without slides. So, since I have them typed up, I’m posting them below.
