CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers. You can use CodeBase to write high performance database applications that are multi-user compatible with FoxPro, dBASE and Clipper, create anything from a Java applet to a full-blown Windows database application to a simple DOS utility, write scalable applications that can be deployed as single-user, multi-user or client/server, all without changing any of your source code, and port your applications to Windows, DOS, UNIX, OS/2, and Macintosh. There's a free 30-Day Test Drive option available. CodeBase is available for every major operating system including Windows XP, 2000, 9x, NT, CE, DOS, OS/2, Macintosh, and a variety of Linux and UNIX platforms including Solaris, SunOS, HP/UX, AIX, SCO, and others.
The Item Response Theory (IRT) library is a set of functions to estimate the items and abilities from the responses of subjects to a questionnaire. The IRT models supported are the logistic model, the nominal response model, the graded response model, and smoothing by penalization and kernel. The project also hosts rirt, a package for the R Project for Statistical Computing, and eirt, an add-in for Excel.
Itzam/Sharp is a C# class library for creating and manipulating keyed-access database files containing variable-length, random access records. Information is referenced by a user-defined key value; indexes may be combined with or separate from data. Itzam/Sharp implements the Itzam engine (see Itzam/Core and Itzam/Java) in 100% managed C#. At 32K, the Itzam/Sharp engine is both small and powerful, and it works with any .NET language, including F# and Visual Basic.
Stunnix VBS-Obfus protects your VBScript code from potential analysis, study, or reworking by unwanted parties. It's both an obfuscator and encoder for the VBScript code. It converts the VBScript in raw .vbs files, or in ASP or HTML pages into a highly obfuscated form, making it extremely difficult to study, analyse, or reuse, while fully retaining functionality of the original source code. It optionally adds expiration and hostname checking. It has a lot of options to control all aspects of code hiding, and has full support for all syntax constructs. It is designed to be multi-module aware.
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.
Visual Paradigm for UML is a Unified Modeling Language (UML) design tool that supports all UML diagrams, SysML diagrams, and entity relationship diagrams. Visual Paradigm for UML provides extensive use case modeling features, including full function UML use case diagram, flow of events editor, use case/actor grid, and activity diagram generation. Visual Paradigm for UML produces system documentation in PDF, HTML, and MS Word formats. A developer can design system documentation with the template designer. A system analyst can estimate the consequences of changes with impact analysis diagrams, such as matrix and analysis diagram. Visual Paradigm for UML generates Java code.
Meta.Numerics is a Mono-compatible .NET library for scientific and numerical programming. It includes functionality for matrix algebra (including SVD, non-symmetric eigensystems, and sparse matrices), special functions of real and complex numbers (including Bessel functions and the complex error function), statistics and data analysis (including PCA, logistic and nonlinear regression, statistical tests, and nonuniform random deviates), and signal processing (including arbitrary-length FFTs).
JOpt.ASP is a consistent advancement of JOpt.NET that exposes the unique JOpt vehicle routing capabilities via standard HTTP/SOAP interfaces. JOpt.ASP has been designed for enterprise applications and Web-based solutions that are based on ASP.NET. JOpt.ASP provides its optimization facilities through a stateful Web service that comes with a comfortable programming interface that is very similar to JOpt.NET.
