PSX is a PHP framework for creating RESTful APIs. It helps you to build clean URLs serving Web standard formats like JSON, XML, Atom, and RSS. It includes a handler system that abstracts away SQL queries from domain logic, a routing system that executes correct controller method for the location of the controller and the method annotation, and a flexible data system that converts database records into formats like JSON, XML, Atom, and RSS. A lightweight DI container handles dependencies. The controller supports request and response filters that can modify the HTTP request or response, and filters are provided for Basic and Oauth authentication.
Valentina is cross-platform SQL and non-SQL columnar database that allows development of client-server [Web] solutions and applications with an embedded local database using the same sources. Valentina DB provides an Object-Relational model, but you can also mix Relational and Extended Navigational. It introduces a revolutionary model abstraction "Link" that greatly simplifies db schema, and therefore simplifies SQL queries. It supports disk and in-memory databases, and field types including Bit, BLOB, Pictures, and Enum. It provides advanced features such as triggers, views, stored procedures, regular expressions, XML, full-text search, and calculated fields. It exists as Valentina Server, Valentina Studio, and a set of Valentina ADKs for all major programming languages.
StelsCSV is a JDBC driver that allows performing SQL statements and other JDBC operations upon text files (comma separated, tab-separated, fixed length, etc.). Using this driver, users can easily create a simple database consisting of plain text files. The driver can be used for writing data importing programs and migration tools. It supports most keywords of ANSI SQL92, table joins, INSERT, UPDATE, and DELETE statements, data types, aggregate, converting, string, and user-defined SQL functions.
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.
HDBC provides an abstraction layer between Haskell programs and SQL relational databases. This lets you write database code once, in Haskell, and have it work with any number of backend SQL databases (MySQL, Oracle, PostgreSQL, ODBC-compliant databases, etc.) HDBC is modeled loosely on Perl's DBI interface, though it has also been influenced by Python's DB-API v2, JDBC in Java, and HSQL in Haskell.
TbsSQL is a small wrapper class for working with SQL databases within PHP scripts. It has few methods and two properties and it’s only one file per database for installation. Its most interesting feature is that it can protect and format values before merging them into the SQL statement. It has a cache feature, a trace mode, a debug console, and it can return data as arrays, standard objects, specific class objects, or clone objects. It can also delete PHP connection variables after making the connection.
