nf1db is an in memory database engine with SQL and JDBC interfaces. It supports transactions, commands from the SQL-2003 standard, all major data types, a number of functions, default and null values, auto-increments, constraints, primary and foreign keys, set operations, implicit and explicit joins, nested SELECT statements, quantity limits in SELECT statements, and much more.
Awake SQL is a virtual JDBC Driver and a framework that enables remote JDBC access through HTTP. It allows Android and Java desktop app developers to use regular JDBC calls to access remote SQL databases in the cloud. It implements the main data types including blobs/clobs, and supports transactions. Security has been taken into account from the design stage: server-side configuration lets admins specify strong authentication and security rules in order to protect the databases.
websqlclient (WSQLC or wiskl) is a lightweight HTTP server which allows an end user to access JDBC data sources via automatically-generated data entry screens. It is designed to be used with standard Web browsers and wireless tablet PCs, and is highly configurable. It can connect to any JDBC data source. Its main purpose is to provide rapid data-model-driven development. The websqlclient data entry forms are generated by querying the database system table information, but can be configured manually. websqlclient includes a database-agnostic data loading utility (SQLLoader), a data unloading tool (SQLExport), and SQL scripting capabilities.
BitNami JRubyStack provides a fast, easy way to develop and deploy Ruby on Rails applications on a Java runtime using JRuby. It includes JRuby, Rails, Java, Tomcat, the GlassFish gem, MySQL, and Subversion. It supports Windows, Linux, and Mac OS X, so you can share the same Rails environment on multiple platforms.
StelsXML is a JDBC type 4 driver that allows you to perform SQL queries and other JDBC operations on XML files. It allows you to easily access data contained in XML documents using the standard SQL syntax and XPath expressions. The driver is completely platform-independent. It supports most keywords of ANSI SQL'92, XPath expressions for defining tables and columns, inner and outer table joins, aggregate, numeric, string, conversion, and user-defined SQL functions.
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.
