Todd Hoff has posted a link to a Los Alamos National Lab presentation on Graph Databases. In this paper they provide a revisit on the classic RDBMS vs Graph database debate.
The Relational Database hasn’t maintained its dominance out of dumb luck. Instead the RDBMS has consistently outperformed while providing the most general use capability of all the variety of platforms that have been[Read more...]
The last 24 months has seen the introduction of Map/Reduce functionality into the data processing arena in various forms. Map/Reduce is a framework for developing scalable data processing functionality, and was popularized by Google (see this earlier post).
Pure players like Hadoop are starting to find their own niche, helped by organizations such as Cloudera. However there has been a number of for & against arguments relating to Map/Reduce functionality inside the database.
These arguments are now really serving a moot point. Customers have recognized value in Map/Reduce prompting some (b)leading edge database vendors to[Read more...]
A bit of fun for a Sunday. Below is the list of my top 10 interesting companies in Data Management right now. Interesting to me means doing new stuff and being somewhat disruptive, or have a “watch and see” quality about them. Note this is about companies not data management applications.
While I find a bunch of other data management applications interesting (PNUTS, Cassandra, Redis etc) these aren’t really encapsulated in a company with a go to market strategy.[Read more...]
A great post from Jonathan Ellis on "Why you won't be building your killer app on a distributed hash table"
Scroll down to see my comment. I agree a simple DHT is not a suitable solution for mainstream data management issues, but also I think that there is a gap between RDBMS and DHT.
I met with a friend of mine in New York recently who runs a credit card processing end-point company. They specifically built their business around a non-relational database platform and feel they would have major issues had they chosen to build their business around a traditional[Read more...]
This is the first detail post in a series I am doing focusing on the issues that exist today with the Relational Database. This first post is on the deployment model. It could be argued that this isn’t directly related to the “relational database” but rather is an implementation model problem. I disagree with this as many characteristics of the relational[Read more...]
The relational database has been the core mechanism for structured data storage and retrieval for the past 30 years. My career so far has focused around the relational database, whether it be from a development, administrator or investment perspective. In all this time the RDB has been the best generic option available for[Read more...]
Recently, a lot of new non-relational databases have cropped up both inside and outside the cloud. One key message this sends is, "if you want vast, on-demand scalability, you need a non-relational database".
If that is true, then is this a sign that the once mighty relational database finally has a chink in its armor? Is this a sign that relational databases have had their day and will decline over time? In this post, we'll look at the current trend of moving away from relational databases in certain situations and what this means for the future of the relational database.[more]
So it’s that time of year again when everyone puts out their predictions for the year ahead. I think predictions are a bit of a waste of time because to be interesting predictions have to be big, but a year really isn’t all that long so actual changes over the course of 2009 are likely to be just small progressions. So instead I have been thinking about the top issues that we face heading into 2009 and here is my Top 10 list for issues in Data Management. In this post I avoid offering solutions to these issues, while I have several ideas on solutions these can be the subject of subsequent posts.
While scalability is on my list it is at number 10 because against popular belief, scalability is only an issue for a very small number of data based applications. Almost all data based[Read more...]
There are a few podcasts I tend to listen to as I have time. Since I work with a wide range of technologies, I've tried to group them together into a semblance of order. There are a few others I am evaluating, but since I haven't listened to a large enough body of work, I'll refrain from listing them at this time. If there's one you think is particularly valuable or interesting that I don't have listed, please leave it in the comments.
.NET Rocks - http://www.dotnetrocks.com/
This is one of the best done podcasts out there and they cover anything and everything related to Microsoft .NET. That's a broad brush of most anything that interacts with Microsoft technologies. This one runs twice a week and is about an hour each[Read more...]
I've been dealing with a security product from a security company in recent days that breaks best practices with respect to the database configuration. This has reminded me of the list of issues I've seen over the past six months that have raised my ire. I'll rail mostly at products that use SQL Server as the back-end, but I'll save the last example for one that uses MySQL. It's not the database products that are weak. It's the application implementation on them!
Case #1: Don't EVER use SA and don't enable the network if you don't have to!
This said security product recommends the use of SQL Server if you are using it on over 1,000 users. Okay, no problem. It wants its own instance. Okay... that raises a flag in and of itself. Is performance really that bad? Well, no, not
