| Information systems and computer sciences use data modeling to manage and organize large quantities of structured and unstructured data. A data model describes the information to be stored in vast data management systems like relational databases. Data models do not include unstructured data such as email messages, word processing documents, digital video, audio or image files. Furthermore, data modeling establishes implicit and explicit constrains and limitations of the structured data. A data model is formally known as data model theory. A professional Information Technologies engineer may work as a Data Modeling Analyst for businesses using enterprise data management tools and technologies. A Data Modeling Analyst or Data Model Manager will be familiar with process modeling, understanding data modeling concepts, data modeling tools, entity relationship diagramming, dimensional data modeling and physical or logical data modeling. Data Modeling Analysts use data modeling functions to supply an accurate representation of the enterprise. Secondly, data modeling is used to accurately reflect the data of the organization. Based on this information, a database is created. Tutorials on Data Management in Data Modeling explain the basic concepts behind data modeling, its uses with enterprise management, terminology related to data modeling, the history of data modeling and instructions on various models within data modeling.RAQ Report: Web-based Excel-like Java reporting tool |
