AutoDesk using 3D Modeling has been integrated into many large jobs in Canada while in the USA it has been used regularly for about 10 years. This program is called Building Information Modeling and for short‚ BIM. There are many companies that do not know about BIM or have heard of it but have never used it or seen it being used. 1.2 Specific Background The purpose of this report is to inform people within the construction industry about the available software and the importance of 3D modeling throughout

Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

DATA BASE SYSTEM Introduction Data is a virtual organizational resource which is an important input in an information system. This data resource is traditionally called the data base. It is from this data base that data is processed and converted into information to satisfy information needs of the organization. Nowadays we find that the internal and external information resources available to organizations are increasing at a rapid rate‚ due to which data bases are becoming larger and
