Fix8 is a modern open source C++ FIX framework featuring complete schema driven customisation, high performance, and fast application development. The system is comprised of a compiler for generating C++ message and field encoders, decoders, and instantiation tables, a runtime library to support the generated code and framework, and a set of complete client/server test applications. For the same message, Fix8 encodes 3.2 times faster and decodes 2.3 times faster than Quickfix, an average of 2.7 times. In other words, it reduces encode latency by 69% and reduces decode latency by 56%.
SchemaCrawler is a Java API which makes working with database metadata as easy as working with ordinary Java objects. It is also a database schema discovery and comprehension and schema documentation tool. You can search for database schema objects using regular expressions, output the schema and data in a readable text format, and find potential design issues with lint . The output is designed to be diff-ed against other database schemas. SchemaCrawler supports almost any database which has a JDBC driver, but for convenience is bundled with drivers for some commonly-used RDBMS systems. SchemaCrawler works with any operating system which supports Java.
Qore PostgreSQL Module is a DBI driver module for the Qore programming language to communicate with PostgreSQL databases. The PostgreSQL driver transparently handles client and server character encodings, supports multi-threading, transaction management, stored procedure execution, and more.
GeoTypes is a Python library that implements both the OpenGIS/PostGIS and standard PostgreSQL geometry types. It integrates with the psycopg Python/PostgreSQL interface. It provides implementations of all of the OpenGIS/PostGIS classes, except (x,y,m) and (x,y,z,m). It currently supports the EWKB, HEXEWKB, WKB, and WKT formats.
JWPL is a language independent, database-driven, high performance Wikipedia API that provides structured access to information nuggets like redirects, categories, articles, and link structure. It contains a Mediawiki Markup parser that can be used to further analyze the contents of a Wikipedia page or standalone with other text, TimeMachine, which reconstructs a snapshot of Wikipedia from a specific date, or multiple snapshots from a time span, and RevisionMachine, which offers efficient access to the history of articles using a dedicated storage format which decreases storage space by 98%. This enables random access to the whole revision history without requiring several terabytes of storage for a single Wikipedia dump.
LiteSQL is a C++ library that integrates C++ objects tightly to a relational database and thus provides an object persistence layer. LiteSQL supports SQLite3, PostgreSQL, and MySQL as backends. LiteSQL creates tables, indexes, and sequences to database and upgrades schema when needed. In addition to object persistence, LiteSQL provides object relations which can be used to model any kind of C++ data structures. Objects can be selected, filtered, and ordered using a template- and class-based API with type checking at compile time.
