for use immediately rather than using the CAD drawing with dimensions to print as a detail drawing to then tabulate etc. Complex shapes and tool paths such as curvy three dimensional designs (for example see figure 1) are much more achievable using 3D modelling because there may be need for more than one tool path at a time which would not be very fun to programme manually.

systems lean on the relational model and data warehouses on the multidimensional model. The phrase On-Line Analytical Processing (OLAP) means summarizing‚ consolidating‚ viewing‚ and synthesizing data according to multiple dimensions. The process of modeling data warehouse may start from operational system’s database. It may be helpful to convert a relational database schema into a multidimensional database schema in order to discover dimensions that are hidden in a relational database. However‚

The Bobo Doll Experiment and Learning Through Modeling. The Dr. Albert Bandura’s hypothesis was that children’s aggressive behavior is learned through observing and imitating others. Like many other behaviorists‚ Dr. Bandura believed that aggression is learned through behavioral modeling process‚ rather than inherited through genetic factors. He positioned that modeling processes toward nurture extreme on a nature-nurture continuum. The exposure to an aggressive behavior through TV‚ PC games and

DATABASE A database is a collection of data organized to meet users’ needs. Why This Matters Without data and the ability to process it‚ an organization would not be able to successfully engage in business activities‚ nor would it be able to generate reports to support knowledgeable workers and decision makers which in turn help’s to achieve organizational goals; it would not be able to pay employees‚ send out bills‚ and order new inventory. Databases have made it possible to map the structure
