Software Map

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.

Osage is a JDBC-based object-relational mapping system. It maps Java objects to RDBMS, generates SQL for retrieving, saving, and deleting objects, converts between XML and RDBMS, and can auto-generate keys, and maintain dependent objects and relations.

ESE (pronounced "easy") stands for "Enterprise
SmartEiffel". Its aim is to build enterprise-level
tools and libraries for SmartEiffel.

VMap/J is a Java-based dynamic video mapping
system with GIS information, shortest path
routing, built-in database, and an applet-based
visual interface.

Data stream processing toolkit (dspt) is intended for processing huge amounts (gigabytes) of data in an efficient manner. The structure of the data files is user-defined, and the queries are written in a declarative style. Currently included algorithms range from simple filtering on predicates to aggregation and sorting. It also includes some convenience classes (e.g. for accessing BerkeleyDB databases). The toolkit does not offer as wide a range of operations as an RDBMS, but some measurements of simpler queries have shown it to be more than 10x faster than PostgreSQL.

AjaxToaster lets you easily create JSON and XML
based Web services for your Web applications. It
runs as a servlet in any application server or
with its own standalone server.

KekeDB is a simple Berkley DB based database
server, to be used in embedded Linux systems. It
implements a subset of SQL-92, and uses lightly
encrypted connections with Digest authentication.

Ashpool is a lightweight XML Database written in Java. Its goal is to use standard SQL92 syntax to query, add, update, and delete XML documents that hold to a table like structure.

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.

isk-daemon is a standalone server capable of
adding content-based (visual) image searching to
any image-related Web site or software. All its
services are exposed through an XML-RPC or SOAP
interface.

Schevo is a next-generation DBMS that focuses on
database integrity, rapid development, user
interface generation, rich schema definition, and
assisted schema evolution. Schevo was designed to
address shortcomings in SQL-based relational
databases where they do not match well with
object-oriented programming languages. Schevo
solves this problem by combining relational
features with the object-oriented programming
language Python. Schevo includes a GUI Navigator
that can display a fully interactive interface
into any Schevo database, using the metadata
available within a Schevo database file.

BlackRay is a relational database system designed to offer performance features commonly associated with search engines. It offers SQL support and sophisticated operational and management features. Load-balancing and operational stability by means of N+1 redundance are included. BlackRay is called a "Data Engine" since it combines traditional, relational database features and SQL with the power and flexibility of search engines. It is a true hybrid, offering transaction support, data-versioned snapshots, and sophisticated function-based indices. Wildcards, phonetic, and fuzzy logic searches are supported, as well. BlackRay supports a subset of the SQL92 standard and provides JDBC/ODBC/native driver options via the PostgreSQL protocol, in addition to an API based query option. The project is released under the GPLv2, with some drivers available under BSD-style licenses. Commercial support contracts are available as well.

KWC (Key Width Calculator) calculates the bit count required to represent a specified number of combinations. It additionally calculates key width in platform bytes (C char type), actual number of combinations covered by that many bits, and the difference and ratio of requested and actual coverage.
