Unreferenced stub auto yes date December 2009 Unreferenced article date October 2010 Orphan date February 2009 Enterprise Data Modeling is the practice of creating a graphical model of the data used by an enterprise or company. Typical outputs of this activity include Entity relationship diagrams Entity Relationship Diagrams ERD , XML Schema W3C XML Schemas XSD , and an enterprise wide data dictionary . Producing such a model allows for a business to get a helicopter view of their enterprise. In EAI Enterprise Application Integration an EDM allows data to be represented in a single idiom, enabling the use of a common syntax for the XML of services or operations and the physical data model for database schema creation. Data Modeling Tools for Entity Relationship Diagrams that also allow the user to create a data dictionary are usually used to aid in the development of an EDM. The implementation of an EDM is closely related to the issues of data governance and data stewardship within an organization.

In datamodeling , the cardinality of one data table with respect to another data table is a critical aspect of database design. Relationships between data tables define cardinality when explaining how each table links to another. In the relational model, tables can be related as any of many to many , many to one rev. one to many , or one to one . This is said to be the cardinality of a given table in relation to another. For example, consider a database designed to keep track of hospital records. Such a database could have many tables like a Doctor table full of doctor information a Patient table with patient information and a Department table with an entry for each department of the hospital. In that model There is a many to many relationship between the records in the doctor table and records in the patient table Doctors have many patients, and a patient could have several doctors a one to many relation between the department table and the doctor table each doctor works for one department, but one department could have many doctors . one to one relationship is mostly used to split a table in two in order to optimize access or limit the visibility of some information. In the hospital example, such a relationship could be used to keep apart doctor s personal or administrative information. A Entity relationship diagram Crow.27s Foot crow s foot shows a one to many relationship, single line is a one to one relationship. UML Modeling UML class diagram may be used for datamodeling. In that case, relationship are modeled using UML associations, and multiplicity is used on those associations to denote cardinality .

expert date October 2010 unreferenced date October 2010 Simulation modeling is the process of creating and analyzing a Digital prototyping digital prototype of a physical model to predict its performance in the real world. Simulation modeling is used to help designers and engineers understand whether, under what conditions, and in which ways a part could fail and what loads it can withstand. Simulation modeling can also help predict fluid flow and heat transfer patterns. Uses of Simulation Modeling Simulation modeling allows designers and engineers to avoid repeated building of multiple physical prototypes to analyze designs for new or existing parts. Before creating the physical prototype, users can virtually investigate many digital prototypes. Using the technique, they can Optimize geometry for weight and strength Select materials that meet weight, strength, and budget requirements Simulate part failure and identify the loading conditions that cause them Assess extreme environmental conditions or loads not easily tested on physical prototypes, such as earthquake shock load Verify hand calculations Validate the likely safety and survival of a physical prototype before testing Typical Simulation Modeling Workflow Simulation modeling follows a process much like this Use a 2D or 3D CAD tool to develop a virtual model, also known as a digital prototype, to represent a design.

Procedural modeling is an umbrella term for a number of techniques in computer graphics to create 3D models and texture mapping textures from sets of rules. L System s, fractal s, and Generative Modelling Language generative modeling are procedural modeling techniques since they apply algorithm s for producing scenes. The set of rules may either be embedded into the algorithm, configurable by parameters, or the set of rules is separate from the evaluation engine. The output is called procedural content, which can be used in computer games, films, be uploaded to the internet, or the user may edit the content manually. Procedural models often exhibit database amplification, meaning that large scenes can be generated from a much smaller amount of rules. If the employed algorithm produces the same output every time, the output need not be stored. Often, it suffices to start the algorithm with the same random seed to achieve this. Although all modeling techniques on a computer require algorithms to manage and store data at some point, procedural modeling focuses on creating a model from a rule set, rather than editing the model via user input. Procedural modeling is often applied when it would be too cumbersome to create a 3D model using generic 3D modeler s, or when more specialized tools are required. This is often the case for plants, architecture or landscapes.

Unreferenced date December 2009 ERP modeling , abbreviated to ERP , is the process of reverse engineering an Enterprise Resource Planning software package in order to align it to an organizational structure. Usage Although ERP modeling could possibly be performed by several methodologies, this entry deals with ERP modeling using Object Process Methodology , or OPM. OPM appears to be a usable methodology for modeling ERP systems, as the methodology focuses on optionality within objects and processes of an ERP system. ERP modeling is done by analyzing the optionality within an ERP system to identify the different functions of the system that the end using company needs, regarding its organizational structure. Reverse engineering both ERP system and organizational structure to the same level of granularity makes both layers compatible for aligning the package in the organization. Theory A Global Business Process Model is created which represents the whole ERP software product. This model is layered in 3 deeper levels. The first level is the System Configuration Level , which scopes on high level optionality on the entire system. Option definition is therefore static once a high level option of the ERP system is chosen to be used within the organization, the choice cannot be made undone. One level deeper is the Object Level , which scopes on single data objects. The optionality on this level is more dynamic . The deepest level is the Occurrence level , which analyses single process occurrences. Because this level elaborates on object parameters, the optionality is very dynamic , meaning that options can easily be altered. The meta model below depicts the optionality levels of ERP modeling.

Loop modeling is a problem in protein structure prediction requiring the prediction of the chemical conformation conformations of loop biochemistry loop regions in protein s without the use of a structural template. The problem arises often in homology modeling , where the tertiary structure of an amino acid sequence is predicted based on a sequence alignment to a template , or a second sequence whose structure is known. Because loops have highly variable sequences even within a given structural motif or protein folding protein fold , they often correspond to unaligned regions in sequence alignments they also tend to be located at the solvent exposed surface of globular protein s and thus are more conformationally flexible. Consequently, they often cannot be modeled using standard homology modeling techniques. More constrained versions of loop modeling are also used in the data fitting stages of solving a protein structure by X ray crystallography , because loops can correspond to regions of low electron density and are therefore difficult to resolve. Regions of a structural model that were predicted by loop modeling tend to be much less accurate than regions that were predicted using template based techniques. The extent of the inaccuracy increases with the number of amino acid s in the loop. The loop amino acids side chain s dihedral angle s are often approximated from a rotamer library, but can worsen the inaccuracy of side chain packing in the overall model. Andrej Sali s homology modeling suite MODELLER includes a facility explicitly designed for loop modeling by a satisfaction of spatial restraints method.
