Olá
Fábio, parece que o derby que vem com o cloudscape é free para aplicações embutidas. Veja o que está escrito no artigo da IBM Cloudscape Version 10: A technical overview
[color=darkblue]
. . . .
Prelude
Cloudscape is the original zero admin, embeddable, all java, relational database that entered the marketplace in 1996. In August 2004 IBM contributed Derby, a copy of its Cloudscape 10.0 relational database product, to the Apache Software Foundation (ASF) to help accelerate innovation around data-driven Java applications. IBM will continue its IBM Cloudscape commercial offering, which will now be based on the core Derby engine.
Not surprisingly, the existence of two names side-by-side, Cloudscape and Derby, might cause some confusion. With that in mind, this section hopes to clarify what is in the Derby engine and what is in the IBM Cloudscape product. We mention features you probably won’t recognize yet; but, rest assured, we describe them later in this technical article.
This technical article uses “Derby” when referring to any feature that is part of the open source database engine, including:
* The core RDBMS engine.
* The embedded JDBC Driver.
* The Network Server.
* Javadoc documentation.
. . . .
IBM Cloudscape Features
The Derby software includes so many capabilities, what more could you possibly want?
The IBM Cloudscape commercial product ships Derby and additionally includes:
* Technical Support
* IBM DB2 UDB Universal JDBC Driver for use with the Derby Network Server
* The IBM Cloudscape manuals and error messages translated into nine languages
* Features to jump start developers who are new to Java and/or Derby, including:
o Product installers for Windows and Linux that install the Java Runtime Environment (JRE) and generate Windows batch files and UNIX scripts for setting the environment.
o Sample databases.
o Sample Java programs that show how to work with embedded mode and Network Server mode.[/color]
Mas também parece que para usar em um servidor deixa de ser free. Será que estou entendendo corretamente? A licença da IBM é um porre para entender.
