Inside c-treeACE: Transactional Technology

In last month's issue we introduced the c-treeACE database engine from the inside with its core technology. In this issue we build upon that core functionality and describe the transactional technology available that drives many of the advanced features of c-treeACE.

The Transactional Technology layer includes the low-level functions to control and maintain transaction integrity, guaranteeing complete recovery of data should an unexpected outage occur, such as hardware or power failures. c-treeACE is fully ACID compliant:

Atomicity
Consistency
Isolation
Durability

As such, c-treeACE provides the highest levels of transaction integrity. With the c-treeACE transaction logging facility, many advanced features can be enabled such as dynamic dumps with complete roll forward capability and complete index data backup; replication to failover sites; and transaction history for auditing.

Extreme Auditing with Transaction History

Ever wonder about additional advanced auditing of your database activity? Auditing of database activity has been part of computing history since the earliest days in the form of audit logs and trails. Most applications take responsibility to build and maintain their proprietary secure set of change logs. c-treeACE provides built-in capabilities to track changes at their source as an additional level of security.

c-treeDB Does Java the Record-Oriented Way

Relational databases were a standard solution long before Java was created in the Sun laboratories. Leveraging this technology was an easy choice at that time and JDBC became the de facto standard in data environments.

As with most “one-size-fits-all” solutions, a fully relational approach may not always be the most appropriate choice. Introducing c-treeACE Java to the Java development community.

The Kissing Cousins of Java and .NET

The Java programming language initially began as a project at Sun Microsystems over two decades ago. It has enjoyed wide success even though it was a technology considered ahead of its time and almost never came to be. As part of the Windows product strategy, Microsoft chose a different approach with a unique language portability feature over platform portability. See how the two compare… and contrast.

FairCom Technology Overview

eNewsletter

For over fifteen years National Public Radio has controlled and managed its entire satellite network radio broadcasts with an application built by Chesapeake Computer Group with FairCom's database technology. This system controls audio routing switchers, makes contact closures for tape recording machine starts and On-Air and Warning lights, controls transmitter parameters, digital audio storage systems and other devices required to operate its broadcasting network.

FairCom's technology provides the performance and stability required to capture and process the data used to operate and control an international satellite communications system. An application such as this requires absolute assurance that its database will provide the accuracy, data integrity, stability and performance required by the most demanding mission-critical embedded technology. In addition, FairCom's portability and scalability has allowed the NPR broadcast network to expand and move into the full international position it occupies today, providing radio network programming to every US military facility and many other international organizations world wide.
