[WIP] Layered stream provides a descendant of TStream class that is intended for situations, where there is a need for some (possibly multi-layered) processing of streamed data, and parallel processing is not desirable or possible.
Delphi and Lazarus HTML Label component
. Delphi Lightweight, language-independent software stack for point-to-point RPC implementation. Thrift provides clean abstractions and implementations for data transport, data serialization, and application level processing. The code generation system takes a simple definition language as input and generates code across programming languages that uses the abstracted stack to build interoperable RPC clients and servers. Thrift makes it easy for programs written in different programming languages to share data and call remote procedures. With support for 28 programming languages, chances are Thrift supports the languages that you currently use.
ACS ( Audio Components Suite ) is a freeware cross-platform set of components designed to perform different sound-processing tasks. It supports reading the audio data from CD, different file formats, for example wav,mp3,wma,ogg,mac and others, output to soundcard and files is also possible. Between input and output you can work with the data, different converters, mixers and processors are available.
. Delphi FPC Cross-platform numerical analysis and data processing library. It supports several operating systems Windows and POSIX, including Linux. ALGLIB features include: Data analysis classification/regression, statistics; Optimization and nonlinear solvers; Interpolation and linear/nonlinear least-squares fitting; Linear algebra direct algorithms, EVD/SVD, direct and iterative linear solvers; Fast Fourier Transform and many other algorithms.
UMDS is small, strong and expansible project. The model offers a uniform method of conceptual view of the diverse data as a sequence of bits and a uniform method of keeping and processing this sequence on the external storage.
Zorba is a general purpose XQuery processor implementing in C++ the W3C family of specifications. It is not an XML database. The query processor has been designed to be embeddable in a variety of environments such as other programming languages extended with XML processing capabilities, browsers, database servers, XML message dispatchers, or smartphones. Its architecture employes a modular design, which allows customizing the Zorba query processor to the environment’s needs. In particular the architecture of the query processor allows a pluggable XML store (e.g. main memory, DOM stores, persis
HALCYON/2 is a Turbo Pascal routines handle processing for dBase III/IV files, including memo (.DBT), index (.NDX), and data (.DBF) files.
Class designed to ease calculation and management of multilayered and/or multi-stage progress (eg. progress of a long and complex data processing).
ALGLIB is a cross-platform numerical analysis and data processing library. It supports several programming languages (C++, C#, Delphi) and several operating systems (Windows and POSIX, including Linux)
