Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
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.
Google Map GPS Cell Phone Tracker allows you to track Android, iOS, Windows Phone, and Java ME cellphones using Google Maps. It has two parts, a server and phone clients. You have a choice of two servers, using asp.net and SQL server or PHP and MySQL. The server software allows you to view cellphone locations in realtime using Google Maps and store routes and view them later. The client applications send their locations to the website periodically. All four applications work properly in the background and are written natively on each platform.
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).
SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is primarily used with common scripting languages such as Perl, PHP, Python, Tcl/Tk, and Ruby, however the list of supported languages also includes non-scripting languages such as C#, Common Lisp (CLISP, Allegro CL, UFFI), Java, Modula-3, OCAML, Octave, and R. Also several interpreted and compiled Scheme implementations (Guile, MzScheme, Chicken) are supported. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG can also export its parse tree in the form of XML and Lisp s-expressions.
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.
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.
