ADODB is a set of advanced PHP database abstraction classes. It supports MySQL, PostgreSQL, Interbase/Firebird, Informix, Sybase SQL Anywhere, Oracle, MS SQL 7 and 2000, SAP DB, Sybase, DB2, FrontBase, Foxpro, Access, Netezza, LDAP, ODBTP, ADO, and generic ODBC. A metatype system is built in, making it possible to figure out that types such as CHAR, TEXT, and STRING are equivalent in different databases. It also features portable database creation, database-backed session support (with encryption), SQL performance monitoring, and database health checks.
GENESIS (short for GEneral NEural SImulation System) is a general purpose simulation platform that was developed to support the simulation of neural systems ranging from subcellular components and biochemical reactions to complex models of single neurons, simulations of large networks, and systems-level models. It was developed as a research tool to provide a standard and flexible means for constructing structurally realistic models of biological neural systems.
OPAL (Open Physics Abstraction Layer) has two main goals: to provide a high-level physics interface, and to provide an abstract interface that is independent of the underlying physics engines. Although some similar libraries focus mainly on the second goal, OPAL is more focused on the high-level physics interface. Even though the abstract interface is important for comparing physics engines or using multiple physics engines in the same application, the primary concern is giving developers a simple, powerful interface with high-level constructs.
