As an in-memory database system (IMDS) pioneer, it shouldn’t surprise anyone that McObject protects its turf. Early on, we published a whitepaper to highlight the significant differences between an in-memory database versus a database that happens to be in memory (a la deployed on a RAM-disk).

Due primarily to (1) the efforts of McObject (over...

A couple of months ago, I began a two-part series on the misconception that in-house or open source software are lower-cost alternatives to commercial software. In the first part, I addressed in-house/roll-your-own development. In this post, I’ll discuss open source. And, repeating my opening comments from the first post, this is not going to be...

First of all, this is not going to be a rant about/against open source software. McObject offers open source software in our Perst object-oriented embedded database system for Java and .NET.

Rather, this is going to be a two-part post on the misconception that in-house (AKA homegrown, AKA roll-your-own) or open source software are lower cost...

Last week, McObject exhibited at the Seattle (August 24) and Vancouver B.C. (August 26) Real-Time & Embedded Computing Conferences (RTECCs). If you’re not familiar with these events, visit their website, where the About Us page says “This single-day event series is specially designed for people developing computer systems and time critical...

There has been some interesting recent news in our world of databases.

This morning, I picked up my August 15 issue of SD Times. In the lower right corner is a blurb about the 1.0 release of CouchDB, with the full article dominating page 3. Congratulations to the CouchDB team.

In a press release about CouchDB 1.0 that I read earlier in the...

The term 'embedded database' has been around since the mid-1980's. It was originally created to mean a database system that is embedded within application code. In other words, the database management system is delivered as a library that you, the developer, link with your application code (and other libraries) to create an executable....

Some of us here at McObject just read this article on embedded.com titled Making the case for commercial communication integration middleware.

A lot of the suppositions in that article with respect to the case for COTS operating systems and communications middleware also ring true for database systems. From the beginning of McObject, we've...

eXtremeDB 4.0, which was released last month, includes a new, cleaner, interface for creating/opening databases, especially when a database is a hybrid (in-memory and on-disk) database.

Prior to version 4.0, two functions were needed to open a hybrid eXtremeDB database: mco_db_open() and mco_disk_open(). To provide a consistent interface...

On Monday, we announced the release of eXtremeDB 4.0. Evaluation versions of the eXtremeDB In-Memory Database System and eXtremeDB Fusion (hybrid in-memory and on-disk) database system, with and without eXtremeSQL, for 32-bit Windows and Linux are available for download now.

Two central themes summarize the 4.0 release: Leveraging multi-core...

Recently, I tweeted (see http://twitter.com/McGuy) a comment on the claim in this article http://www.javaworld...ty/?q=node/3567 that "SSD performance is limited only by the SATA2 interface throughput."

Somebody replied that 250MB per second sustained read speed = 2GB/s. Add on the bus overhead and you have 3gb's (the...
