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 ...
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.
Website. [1] Arena is a discrete event simulation and automation software developed by Systems Modeling and acquired by Rockwell Automation in 2000. [1] It uses the SIMAN processor and simulation language. As of 2020, it is in version 16. It has been suggested that Arena may join other Rockwell software packages under the "FactoryTalk" brand.
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.
erwin Data Modeler (stylized as erwin but formerly as ERwin) is computer software for data modeling.Originally developed by Logic Works, erwin has since been acquired by a series of companies, before being spun-off by the private equity firm Parallax Capital Partners, which acquired and incorporated it as a separate entity, erwin, Inc., managed by CEO Adam Famularo.
NORMA (Natural ORM Architect for Visual Studio) [ 1 ] is a conceptual modeling tool that implements the object-role modeling (ORM) method.
