deltasql is a tool to synchronize databases with source code, which helps to keep database evolution under control. While developing mid-sized or big applications, developers make changes to the data model that go along with changes to the source code. From time to time, branches of source code are done to stabilize the code that will go to production. A sort of data model branch is also needed. deltasql provides a simple way to collect all scripts that change the data model and means to handle data model branches. The deltasql server runs on Apache and is backed by MySQL.
e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set.
eDB is a very simple and easy-to-use collection of Perl 5 CGI scripts to perform searches on a flat-file database. Search results are displayed using HTML templates that can be modified to fit the user's needs. Pattern-based searches can be refined by using a range of values of a user-specified field. If desired, search results can be displayed using a paging procedure.
The eGenix mxODBC Zope Database Adapter (Zope DA) allows you to easily connect your Zope installation to just about any database backend. Unlike Zope's ZODBC Zope DA, the mxODBC Zope DA works on Windows, Linux, and Solaris using the same interface. It implements thread-safe connection pooling and multiple physical connects per logical Zope connection. You can safely run Z SQL Methods in parallel, achieving much better performance than ZODBC Zope DA or similar database adapters under heavy load. This makes it ideal for deployment in clusters and hosting environments where stability and high performance are a priority.
The eMATgine server is a multi-protocol server, in which users can request/receive results with http, ftp, wap, pop3, or smtp connection. It is a multi-terminal server, so users can use IE, or a wap phone. This server is a full multi-threaded Java server, using an HSQLDB database to provide user management.
exportSQL is a script to export all tables in a MS-Access database file to several text files containing SQL instructions: one to delete tables which are about to be created, another to create tables, and one to insert data into the new tables. The resulting table structure and data will resemble the current Access database as much as possible.
featherCache is a lightweight Java cache implementing a map interface and storing objects on disk. Multiple sections and expiration times are supported. It requires no third party components, has simple integration, and can also be used to store program settings represented by serializable objects. It was used for a long time as a part of the Sight Web agent generator.
