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.
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.
nsFB is an internal AOLserver database driver for the Firebird or Interbase database. It supports reading and writing BLOB data and ARRAY data. It supports the full size of varchar (32765 bytes) or char (32767 bytes). Many configuration options are supported, such as charset, dialect, transaction isolation level, etc. All kinds of data types are supported, such as NUMERIC or DECIMAL.
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.
