The poco c++ libraries are a collection of open source c++ class libraries that simplify and accelerate the development of network-centric, portable applications in c++. the libraries integrate perfectly with the c++ standard library and fill many of the functional gaps left open by it.

poco is built strictly using standard ansi/iso c++, including the standard library. the contributors attempt to find a good balance between using advanced c++ features and keeping the classes comprehensible and the code clean, consistent and easy to maintain.

poco consists of four core libraries, and a number of add-on libraries. the core libraries are foundation, xml, util and net. two of the add-on libraries are netssl, providing ssl support for the network classes in the net library, and data, a library for uniformly accessing different sql databases.
