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.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
KeePass is a light-weight and easy-to-use password manager that removes the need for you to remember many different passwords and makes it more feasible to use different passwords for each account. It manages your passwords in a secure database encrypted with AES and Twofish, which is locked with one master key or a key file.
MagicDraw is a visual UML modeling and CASE tool with teamwork support. It is designed for business analysts, software analysts, programmers, QA engineers, and documentation writers. This dynamic and versatile development tool facilitates analysis and design of Object Oriented (OO) systems and databases. It provides a code engineering mechanism (with full round-trip support for J2EE, C#, C++, CORBA IDL programming languages, .NET, XML Schema, WSDL), as well as database schema modeling, DDL generation, and reverse engineering facilities.
screen-scraper is a tool for extracting data from Web sites. It works much like a database that provides access to the information of the Web. It provides a graphical interface allowing you to designate URLs, data elements to be extracted, and scripting logic to traverse pages and work with scraped data. Once these items have been created, screen-scraper can be invoked from external languages such as .NET, Java, PHP, and Active Server Pages. It can be scheduled to scrape information at periodic intervals, and can automatically write extracted data to CSV files.
Aspose.BarCode is a Java based visual component for generation and recognition of 1D and 2D barcodes to support Java and Web applications. It supports over 29 barcode symbologies like MSI, QR, OneCode, Australia Post, Aztec, Code128, Code11, EAN128, Codabar, Postnet, and USPS. It also supports image output in GIF, PNG, BMP, and JPEG formats. Other features include barcode size and color settings, rotation angles, and captions. You can render barcodes to images, printers, HTTP servlet responses, and graphical objects.
