System Concepts for Data Modeling Crystal M. Reedus CIS 210 November 21‚ 2010 Abstract Data modeling techniques and methodologies are used to model data in a standard‚ consistent‚ predictable manner in order to manage it as a resource. Data models support data and computer systems by providing the definition and format of data. From a modeling perspective‚ the entire problem domain is viewed as a collection of class hierarchies (of objects) that are connected by messages. Data modeling

FISHBONE DIAGRAM The cause-and-effect diagram was initially developed by Japanese quality expert Professor Kaoru Ishikawa. In fact‚ these diagrams are often called Ishikawa diagrams; they are also called fishbone charts for reasons that will become obvious when we look at an example. Cause-and-effect diagrams are usually constructed by a quality team. For example‚ the team might consist of service designers‚ production workers‚ inspectors‚ supervisors‚ quality engineers‚ managers‚ sales representatives

between a file processing system and a database system ANS: Some main differences between a database management system and a file processing system are: * Both systems contain a collection of data and a set of programs which access that data. A DBMS coordinates both the physical and the logical access to the data‚ whereas a file-processing system coordinates only the physical access. * A DBMS reduces the amount of data duplication by ensuring that a physical piece of data is available to all programs

* ------------------------------------------------- Database Management System (DBMS) * Stands for "Database Management System." In short‚ a DBMS is a database program. Technically speaking‚ it is a software system that uses a standard method of cataloging‚ retrieving‚ and running queries on data. The DBMS manages incoming data‚ organizes it‚ and provides ways for the data to be modified or extracted by users or other programs. Some DBMS examples include MySQL‚ PostgreSQL‚ Microsoft Access

DATABASE MANAGEMENT SYSTEM (DBMS) A Database Management System (DBMS) is a software program that typically operates on a database server or mainframe system to manage structured data‚ accept queries from users‚ and respond to those queries. A typical DBMS has the following features (Stair and Reynolds‚ 2004): Provides a way to structure data as records‚ tables‚ or objects Accepts data input from operators and stores that data for later retrieval Provides query languages for searching‚ sorting
