OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.
SILVERCODERS DocStorage is a utility to improve document management. You can have one database for all invoices, guarantees, protocols, and other documents. DocStorage can extract plain text from documents in doc, XLS, PPT, PDF, RTF, ODT, ODS, ODP, docx, XLSX, PPTX, and many other formats. It can use an OCR engine to extract plain text even from scanned documents. It can perform global fulltext search in all documents regardless of format. It supports document versioning, document duplicate detection, document notes, and document signing. It provides full integration with software suites like Microsoft Office and OpenOffice.
Monotone browser (mtn-browse) is an application for browsing Monotone VCS databases without the need of a workspace. The interface allows one to easily select a revision from within a branch, find a revision using complex queries, navigate the contents of a revision using a built-in file manager, display file contents (either using the internal viewer or an external helper application), graph revision histories, compare the changes between different revisions or versions of a file (either using the internal difference viewer or an external application), find files within a revision based on detailed search criteria, display file annotations and easily refer back to the corresponding change documentation, and save files to disk.
Telemeta is a global audio archiving program which introduces useful and secure indexing methods to back up digitized audio files and metadata dictionaries. It is dedicated to backing up any digitized and documented sound from collections of vinyls, magnetic tapes, or audio CDs over a strong database in accordance with many standards. Export functions also encapsulate edited metadata into a compressed file. The object style architecture provides easy developed user-friendly interfaces and a plugin style audio processing.
hiberlite provides C++ object-relational mapping for SQLite 3. Its design and API are inspired by the Boost.Serialization, which means there is almost no API to learn. In contrast to most serialization libraries with SQL serializers, C++ objects mapped with hiberlite behave similar to active record patterns: you are not forced to follow the "read all your data/modify some small part/write everything back" path. It is for people who need reliable data storage, ACID transactions, and simple random access to their data files, and don't like coding in SQL.
Vulpive is webcomic archive software with all of the common features of other online comics, plus some fairly novel ones. Comics can be uploaded for particular dates in advance, and will appear at midnight. There is a separate "calendar view" where comics can be browsed by thumbnail. Three different layout modes are available. Commentary for individual comics is supported. Plot arcs can be organized into chapters. It is easily skinnable by anyone with basic HTML or CSS experience. An automatic RSS feed is provided.
Wikidbase is a powerful and highly flexible combination of two structural extremes of data management systems: a wiki and a database. As such, it has all of the flexibility of a wiki (e.g. any kind of unstructured data can be stored) and the structural data capabilities of a database (e.g. data may be modelled similarly to database fields, tables, and relations, such that structural reports can me made of that data). The functionality is combined in such a way that this general-purpose data management system may be shaped easily, without the need of a database expert, into a custom data management application such as a contact relation management (CRM) system, a knowledge base, a shared calendar system, a project management system, etc.
