ObjectDB for Java/JDO is a powerful yet compact Java Data Objects (JDO) Object Database (ODBMS), written entirely in Java, and compliant with the Java Data Objects (JDO) standard developed by Sun (JSR12). ObjectDB for Java/JDO is designed to efficiently handle databases of various sizes, ranging from a few KBs to hundreds of GBs. Among its features are small footprint, high performance, rapid development, easy deployment, and flexible architecture (1-Tier, 2-Tier, or N-Tier).
This small tool connects to the P6Spy JDBC logger and displays in real time the queries going to the database. It uses an integrated SQL parser to build statistics on the most accessed tables and columns to enable database index creation. Other information is also gathered and displayed, such as the request time for a single request, for a class of request, and for all the requests. Sorting may be done on these views to detect database problems efficiently.
Sequoia provides high availability and performance scalability for databases. It is is the continuation of the C-JDBC project. It provides transparent database clustering (partitioning, replication, etc.). It works with any Java application without code modification and with any database engine. It has been successfully tested with Tomcat, JBoss, JOnAS, WebSphere, MySQL, PostgreSQL, Apache Derby, HSQLDB, SAP DB, Oracle, DB2, Sybase, MS SQL Server, Firebird, and more.
Pervasive.SQL is a high performance, low-TCO database server designed to be easily embedded in applications and devices targeted for Linux, Novell, and Windows environments. Pervasive delivers both transactional and relational access methods to the application in a single box. Based on this unique model, the developer can use the data access model most appropriate for a given task. This means high-transaction volume applications can exploit the performance-optimized transactional access method while reporting, statistical and other complex query tasks are easily addressed through the relational access method.
The Infotrope ACAP Server is an implementation of RFC2244, complete with asynchronous notification of changes, stored search results, ACLs, and data inheritance, etc. It supports TLS and SASL encryption as well as the entire base standard, plus a few optional extensions. ACAP allows applications to store configuration data in a way that is standard, fully interoperable, and easily managed by users, administrators, and technical support teams alike. Infotrope's key features include the ability to randomly crash the server without data loss, and backing up of data (even while it's being written) without losing integrity.
Tyserv is a DBMS for UNIX-like systems. It has isam-like access, transaction control, rollback, commit, exclusive lock, access control by client IP address, and user authentication. If you like old but simple database programming environments like COBOL+VSAM(KSDS) or C+C-ISAM, you will like Tyserv.
