Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
BlueJ is an interactive Java development environment. It provides a unique user interface that presents a graphical display of the application classes and their relationships, and it lets users interactively create objects of any class. Once objects have been created, users can interact with them directly. This interaction mechanism allows for much greater testing and experimentation than in conventional environments. BlueJ is suited for teaching and learning OO and Java.
DashO is a Java application obfuscator, optimizer, and packager. It performs a dependency analysis on the application, removing unused methods and fields. Classes and members can be renamed using the patented Overload-induction renaming algorithm. Byte code optimization, control flow obfuscation, and string encryption can also be selectively applied. Special features include analytics for Java/Android/RIM/J2ME including exception reporting, Android obfuscation and tamper protection, and JAR watermarking.
The DataBrowser is a Java-based tool for browsing virtually any database. It has been tested with Oracle, SQL Server, PostgreSQL/Postgres, MySQL, DB2, and MS Access (among some others). It requires a Java 2 runtime environment. The DataBrowser allows you to execute dynamic SQL, import and export data, view the schema in a treeview, and view query results in a table view. It also logs all SQL executed with the SQLLog feature.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
eXist is a native XML database featuring efficient, index-based XQuery processing. It provides a complete ecosystem for building applications entirely based on XML, XQuery, and related standards. The high-performance XML database engine stores textual or binary data and documents without requiring a database schema. Using XML across all layers makes mapping technologies superfluous and increases productivity. A browser-based IDE and a standardized application packaging system help developers get started quickly.
iSQL(IndependentSQL)-Viewer is a JDBC 2.0-compliant application that can take advantage of platform features such as transactions, running batch modes, and database abstraction. Even in heterogeneous database environments, it supports all database platforms with a JDBC 2.0-compliant driver, such as PostgreSQL, MySQL, and Oracle. It provides a variety of tools to carry out both simple and complex database activities.
JExpress is a Java installer builder and auto-updater. It gives you your choice of a standalone installer, including both native and cross platform installers and updaters for Windows, Mac OS X, Linux, and Solaris, or a Java Web Start one-click install. You create your installer quickly with your choice of a simple wizard or a powerful advanced interface, both included. You can bundle the exact JVM you want with your installer. The auto-updater gives you a continuous revenue stream after the sale. Your software is always up-to-date, so your customers have fewer problems. You also get all the features you expect in a top end installer. Your Java application becomes a native program just like any other. On Windows it's an EXE, on Mac OS X an app bundle, etc. If you need something really special, you can customize your installer by adding simple Java classes. You can even get a source license at a reasonable price.
