Berkeley DB at OpenWorld/JavaOne 2011

It’s the question on everyone’s mind: what is Berkeley DB bringing to OpenWorld this year? Even if you’re more preoccupied with the latest iPhone 5 rumors, (I hear the front facing camera can look into your eyes and tell you what you had for breakfast) Berkeley DB users (or fans) who are planning to attend Oracle OpenWorld in San Francisco about 10 days from now will want to read this post.

As always, we will have a session where you can learn about the cool and interesting things our customers are doing with a key/value data store. But this year, we have two additional general areas of focus: Embedded, and Mobile Applications.

Let’s take a closer look at the embedded front first. As the cost of components like network hardware, flash memory, and microcontrollers continues to fall, OEMs in many verticals are choosing to enhance their product lineup by adding new applications and internet-enabled features. Networked cash registers? That was only the beginning. This was the year cars started getting on the internet, and I already blogged about that. Who knows what the next years will bring?

Whatever our customers are planning, we’ve got solutions that can help. Our first session with an embedded focus is 15185, BDB and Embedded Java presentation. There you’ll learn how we are extending Java’s “write once, deploy anywhere” mantra. With Berkeley DB and Database Mobile Server, you get worry free data management and sync capabilities after you’ve deployed, as well.

Next, over on the JavaOne side we have 25143, Telemetry and Synchronization with Embedded Java and Berkeley DB. This session will feature Java Architect Greg Bollella talking about how these same technologies are enabling telemetry solutions to plug into the enterprise right alongside your existing data and apps. The ability to manage networks of embedded devices using existing enterprise frameworks could prove to be quite revolutionary. The embedded Java platform, when coupled with Berkeley DB and Database Mobile Server, has the ability to do just that. We’re excited about this, and we think our customers will be too.

On the mobile applications side of things Tata Consulting Services (TCS) will be joining us for session 15178, Achieve Ubiquitous Data Access, from Device Databases to Enterprise Repositories. There you’ll learn how TCS is helping their customers deploy mobile applications that maximize the ROI of their existing enterprise infrastructure.

Rounding out the list is our key/value customer highlight session. You thought I forgot, right? No chance! Session 15167 is entitled Transactional Key-Value Storage: Super Simple, Super Fast, Super Flexible. Raghunath Nambiar, an Architect at Cisco, will co-present with us. The topic will be super cool things you can accomplish using the key-value paradigm for data management.

In addition to the sessions, we will have a number of exciting demos for you to check out, both at OpenWorld and JavaOne.

Finally, be on the lookout for an exciting product announcement building on the inherent strengths of the Berkeley DB product family!

Hope to see you there!

Embedded Systems Conference San Jose

The annual Embedded Systems Conference in San Jose was held at the beginning of May. This was Oracle’s first year at the conference, and we did get visitors who were surprised to see us there. However some people, myself included, think we're going to see increased convergence between enterprise and embedded in the coming years. I know we're not alone, because a certain other big name in enterprise systems had a booth right next to ours!

Since embedded is not a topic everyone is familiar with, I want to give a little insight into this conference and the embedded space in general, as I think it is potentially an important growth area for products like Berkeley DB. Since I was an embedded developer myself in a past life, this is familiar territory for me.

Wikipedia defines embedded systems as "a computer system designed to do one or a few dedicated and/or specific functions." It is important to note that embedded is generally considered to be distinct from mobile. Mobile platforms are typically derived in some way from desktop platforms such as Linux, Windows, OSX, and are often more general purpose devices. Before the advent of cheap, high-res, general purpose LCD displays, having a display in your device meant a Cathode Ray Tube (CRT). Embedded devices were traditionally ‘headless,’ meaning they had no display and no generic input device such as a keyboard. Because of this, in the early days developers would commonly develop on desktop machines using a cross toolchain. A cross toolchain is a set of tools designed to build software on a target embedded platform, which was a completely different hardware architecture and OS from the desktop development platform. Nowadays, many embedded platforms are powerful enough that they can run their own toolchains. Such was the case with our demo, more on that below.

Another common aspect of an embedded system is “real time” requirements. A simplified definition would be if a given operation does not complete by a certain time, it’s just as bad as not finishing at all. Real Time Operating Systems, or RTOSes, can provide guarantees about when operations will finish. Real time embedded devices are still quite prevalent in some industries, including military, aviation, industrial manufacturing, and networking. The embedded space has certainly been encroached on by the rise of mobile, but as long as we have mission critical devices there will continue to be a requirement for embedded devices.

Now back to the Embedded Systems Conference. Booth traffic was high, we were averaging about 1 visitor per minute the nearly the whole time I was there. I attribute this partly to curiosity, but mostly to our great giveaways! They did their job, I talked to a number of people who ended up having a genuine interest in what we were showing, and were initially attracted to the booth by our swag. Also we held a drawing for an iPad, which brought a ton of people to register.

Our demo was a temperature sensor attached to a small device called a SheevaPlug, which is a general purpose embedded development device from Marvell. By embedded standards, the SheevaPlug is a very powerful device, and we were able to develop directly on it. The idea behind the demo was that the device represented one of many nodes in a sensor network. Some real world examples of this include weather stations, or monitoring conditions inside laboratories or industrial facilities. Our demo showed the system collecting temperature data, which was then uploaded to Oracle Database. All of this was running on top of Java SE Embedded. The demo was well received. Nearly everyone who listened to me present agreed that the sync functionality would be useful to them, or useful in general if they didn’t need it themselves.

The main purpose of our presence at ESC was to showcase the power, ease of use, and versatility of Java Embedded. When you combine that Berkeley DB and Oracle Database Lite Mobile Server, you get a system that has out of the box capability to move data to and from enterprise storage systems. After a few simple configuration steps, the data stored on the local Berkeley DB or SQLite data store is connected to the enterprise backend. This is a potent combination of features, and one that we feel will be in high demand in the coming years, as M2M and embedded solutions continue to proliferate.
