PDO4You is a class that implements the Singleton design pattern for connecting the database using the PDO extension (PHP Data Objects). It provides an abstraction layer for accessing data, regardless of which database you are using, and ensures that there is a single object instance per database connection. It can connect to several possible SQL databases using the available PDO drivers. Currently it supports MySQL, PostgreSQL, SQLite, MariaDB, Oracle, Microsoft SQL server, Sybase, and CUBRID (a database highly optimized for Web applications). The class can also execute multiple queries at once given a string in JSON format that specifies the type of query, the tables, fields, field values, conditions, etc.
The YB.ORM library aims to simplify writing C++ code that has to deal with SQL databases. The goal is to provide a convenient interface like SQLAlchemy (Python) or Hibernate (Java). The library itself is cross-platform and supports a variety of SQL dialects: SQLite3, MySQL, Postgres, Oracle, and Firebird. Integration with Boost, Qt4, and wxWidgets is built-in. In a typical usage scenario, you would describe your database schema and table relationships in a simple XML-based format, generate SQL code to populate database schema with tables, generate C++ classes, add application-specific logic to the classes, and use these classes in cooperation with the Session object to query objects from the database, create new or modify/delete existing objects, or link and unlink objects using relations. Simple serialization to XML is supported along with connection pooling.
QueryFS is a FUSE-based virtual filesystem that is based on queries. There are plugins to parse various query syntaxes and each query creates a virtual directory. Currently the most elaborate query language is SQL-based; you can either provide access to data stored in an SQL database, or keep an index of files in the SQL database and generate search directories with symlinks to found files. QueryFS and its SQL2 query DSL fully support creation of refinable searches: for example, the author has an index of downloaded email files; one can see all the distinct senders registered in the DB and then go into a directory of one sender and see all accounts that ever received an email from this sender.
