Voldemort does not try to satisfy arbitrary relations and the ACID properties, but rather is a big, distributed, persistent hash table. [2] A 2012 study comparing systems for storing application performance management data reported that Voldemort, Apache Cassandra, and HBase all offered linear scalability in most cases, with Voldemort having the lowest latency and Cassandra having the highest ...
Virtuoso Universal Server is a middleware and database engine hybrid that combines the functionality of a traditional relational database management system (RDBMS), object–relational database (ORDBMS), virtual database, RDF, XML, free-text, web application server and file server functionality in a single system.
Open Pluggable Specification (OPS) is a computing module plug-in format available for adding computing capability to flat panel displays. The format was first announced by NEC , Intel , and Microsoft in 2010.
A program accessing the database is free to decide how the data is to be stored in a record. Berkeley DB puts no constraints on the record's data. The record and its key can both be up to four gigabytes long. Berkeley DB supports database features such as ACID transactions, fine-grained locking, hot backups and replication.
Many of the products included under the FMW banner do not themselves qualify as middleware products: "Fusion Middleware" essentially represents a re-branding of many of Oracle products outside of Oracle's core database and applications-software offerings—compare Oracle Fusion. Oracle acquired many of its FMW products via acquisitions. [3]

A database trigger is like a stored procedure that Oracle Database invokes automatically whenever a specified event occurs. It is a named PL/SQL unit that is stored in the database and can be invoked repeatedly. Unlike a stored procedure, you can enable and disable a trigger, but you cannot explicitly invoke it.
OpenEdge ABL helps developers to develop applications optionally using its own integrated relational database and programming tools. These applications are portable across computing systems and allow access to various popular data sources without having to learn the underlying data access methods.
