Weka (software) Waikato Environment for Knowledge Analysis (Weka) is a collection of machine learning and data analysis free software licensed under the GNU General Public License. It was developed at the University of Waikato, New Zealand and is the companion software to the book "Data Mining: Practical Machine Learning Tools and Techniques".
Not to be confused with Idefix. Example of an IDEF1X diagram. Integration DEFinition for information modeling (IDEF1X) is a data modeling language for the development of semantic data models. IDEF1X is used to produce a graphical information model which represents the structure and semantics of information within an environment or system.

Cantera - chemical kinetics package. Celestia - a 3D astronomy program. CP2K - Open-source ab-initio molecular dynamics program.
NORMA (software modeling tool) NORMA (Natural ORM Architect for Visual Studio) [ 1 ] is a conceptual modeling tool that implements the object-role modeling (ORM) method. The NORMA tool is named after Dr.Terry Halpin's wife Norma Halpin (Terry Halpin, 11am, March 4, 2019) [ 2 ] NORMA is a free and open source plug-in to Microsoft Visual Studio ...
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S, [1] Oregano, [2] or ...
Free and open source system dynamics modelling software with stock and flow modelling, hierarchical models and array variables. System dynamics and discrete event modeling with some agent-based capabilities. Drag and drop user interface builder in Architect versions allows simulations to be published online.
Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.
Data modeling is a process used to define and analyze data requirements needed to support the business processes within the scope of corresponding information systems in organizations. Therefore, the process of data modeling involves professional data modelers working closely with business stakeholders, as well as potential users of the ...
