SaaS and traditional software from the same vendor?

It is extremely difficult to succeed with SaaS (Software as a Service) and packaged software in the same company. There were a few vendors who seemed to pull it off in the 1970s and 1980s, generally industry-specific application suite vendors. But it’s hard to think of more recent examples — unless you have more confidence than I do in what behemoth software vendors say about their SaaS/”cloud” businesses.

Despite the cautionary evidence, I’m going to argue that SaaS and software can and often should be combined. The “should” part is pretty obvious, with reasons that start:

But the “how” of combining SaaS and traditional software is harder. Let’s review why.  Read more

Zoomdata and the Vs

Let’s start with some terminology biases:

So when my clients at Zoomdata told me that they’re in the business of providing “the fastest visual analytics for big data”, I understood their choice, but rolled my eyes anyway. And then I immediately started to check how their strategy actually plays against the “big data” Vs.

It turns out that:

*The HDFS/S3 aspect seems to be a major part of Zoomdata’s current story.

Core aspects of Zoomdata’s technical strategy include:  Read more

“Chilling effects” revisited

In which I observe that Tim Cook and the EFF, while thankfully on the right track, haven’t gone nearly far enough.

Traditionally, the term “chilling effect” referred specifically to inhibitions on what in the US are regarded as First Amendment rights — the freedoms of speech, the press, and in some cases public assembly. Similarly, when the term “chilling effect” is used in a surveillance/privacy context, it usually refers to the fear that what you write or post online can later be held against you. This concern has been expressed by, among others, Tim Cook of Apple, Laura Poitras, and the Electronic Frontier Foundation, and several research studies have supported the point.

But that’s only part of the story. As I wrote in July, 2013,

… with the new data collection and analytic technologies, pretty much ANY action could have legal or financial consequences. And so, unless something is done, “big data” privacy-invading technologies can have a chilling effect on almost anything you want to do in life.

The reason, in simplest terms, is that your interests could be held against you. For example, models can estimate your future health, your propensity for risky hobbies, or your likelihood of changing your residence, career, or spouse. Any of these insights could be useful to employers or financial services firms, and not in a way that redounds to your benefit. And if you think enterprises (or governments) would never go that far, please consider an argument from the sequel to my first “chilling effects” post: Read more

Hadoop generalities

Occasionally I talk with an astute reporter — there are still a few left :) — and get led toward angles I hadn’t considered before, or at least hadn’t written up. A blog post may then ensue. This is one such post.

There is a group of questions going around that includes:

To a first approximation, my responses are:  Read more

Teradata will support Presto

At the highest level:

Now let’s make that all a little more precise.

Regarding Presto (and I got most of this from Teradata)::

Daniel Abadi said that Presto satisfies what he sees as some core architectural requirements for a modern parallel analytic RDBMS project:  Read more

IT-centric notes on the future of health care

It’s difficult to project the rate of IT change in health care, because:

Timing aside, it is clear that health care change will be drastic. The IT part of that starts with vastly comprehensive electronic health records, which will be accessible (in part or whole as the case may be) by patients, care givers, care payers and researchers alike. I expect elements of such records to include:

These vastly greater amounts of data cited above will allow for greatly changed analytics.

MemSQL 4.0

I talked with my clients at MemSQL about the release of MemSQL 4.0. Let’s start with the reminders:

The main new aspects of MemSQL 4.0 are:

There’s also a new free MemSQL “Community Edition”. MemSQL hopes you’ll experiment with this but not use it in production. And MemSQL pricing is now wholly based on RAM usage, so the column store is quasi-free from a licensing standpoint is as well.

Notes on analytic technology, May 13, 2015

1. There are multiple ways in which analytics is inherently modular. For example:

Also, analytics is inherently iterative.

If I’m right that analytics is or at least should be modular and iterative, it’s easy to see why people hate multi-year data warehouse creation projects. Perhaps it’s also easy to see why I like the idea of schema-on-need.

2. In 2011, I wrote, in the context of agile predictive analytics, that

… the “business analyst” role should be expanded beyond BI and planning to include lightweight predictive analytics as well.

I gather that a similar point is at the heart of Gartner’s new term citizen data scientist. I am told that the term resonates with at least some enterprises.  Read more

Notes, links and comments, May 2, 2015

I’m going to be out-of-sorts this week, due to a colonoscopy. (Between the prep, the procedure, and the recovery, that’s a multi-day disablement.) In the interim, here’s a collection of links, quick comments and the like.

1. Are you an engineer considering a start-up? This post is for you. It’s based on my long experience in and around such scenarios, and includes a section on “Deadly yet common mistakes”.

2. There seems to be a lot of confusion regarding the business model at my clients Databricks. Indeed, my own understanding of Databricks’ on-premises business has changed recently. There are no changes in my beliefs that:

However, I now get the impression that revenue from such relationships is a bigger deal to Databricks than I previously thought.

Databricks, by the way, has grown to >50 people.

3. DJ Patil and Ruslan Belkin apparently had a great session on lessons learned, covering a lot of ground. Many of the points are worth reading, but one in particular echoed something I’m hearing lots of places — “Data is super messy, and data cleanup will always be literally 80% of the work.” Actually, I’d replace the “always” by something like “very often”, and even that mainly for newish warehouses, data marts or datasets. But directionally the comment makes a whole lot of sense.

Notes on indexes and index-like structures

Indexes are central to database management.

Perhaps it’s time for a round-up post on indexing. :)
