REALbasic is a cross-platform software development environment for developers who want to create and deliver native applications for Mac OS, Windows, and Linux. For example, you can create an application for Mac OS and Linux from a Windows machine. It is intended for people with all levels of programming experience. It is object-oriented, powerful, and supports advanced programming concepts like inheritance, polymorphism, interfaces, delegates, introspection, etc.
odbcpp is an ODBC C++ library wrapper. The ODBC library itself is a low level C library that has many functions, all of which could return errors. This wrapper checks for errors on every single call to the ODBC interface, so if an SQL statement, a connection, or anything else fails, an exception is generated.
The Feature Data Objects API provides a generic, command-based interface to a number of back-end data source technologies for storing, retrieving, updating, and analyzing GIS (Geographic Information System) data. A provider is a specific back-end implementation of the FDO API that provides access to data stored in a particular data source technology.
hiberlite provides C++ object-relational mapping for SQLite 3. Its design and API are inspired by the Boost.Serialization, which means there is almost no API to learn. In contrast to most serialization libraries with SQL serializers, C++ objects mapped with hiberlite behave similar to active record patterns: you are not forced to follow the "read all your data/modify some small part/write everything back" path. It is for people who need reliable data storage, ACID transactions, and simple random access to their data files, and don't like coding in SQL.
Cego implements a relational and transactional database system with support for the SQL query language. The current release contains the most common database features for basic table manipulation and data retrieval. Indexes, foreign keys, views, and stored procedures are also implemented. Future releases (2.0 and above) will support a multi-node database concept with log file shipping for an automatic database application failover.
