UoP A database can also be referred to as an enormous collection of data that is structured in a specific arrangement so that it is easily accessible as well as being maintained and data is kept up-to-date. Database management systems (DBMS) are essentially applications intended for easy interactions with and by end-users; additional applications within the database are intended to catch/record data as well as examine it. In regards to common use of databases is concerned, they offer

Database Design Paper John Hancock DBM/380 April 23, 2013 April Johnson Database Design Paper Database systems are an organized collection of data. The data is normally organized by a couple different methods; structured and unstructured. Database systems make working in a company a lot easier when an employee is looking for information. By having a database management system in the work place the employees will have improved data sharing, data security, data access and better data integration

Database Design Larry Cohen DBM 380 James Cervi November 10, 2014 Database Design Database Systems A database is a structured group of data that is warehoused in a system. In order for a database to be functional it must be accessible and store large amounts of data. In order for databases to be reliable, in the event of a hardware failure, it must be easily recoverable. Also, the database must be flexible. Meaning, if there is something new that needs to be implemented, the database must

Information is data that has been processed and given context. Databases help to organize the manipulation of data to create information by providing an organizational structure that makes relationships and connections between data explicit. 7. The DBMS serves as the intermediary between the user and the database. Some advantages are improved data sharing, data security, data access, decision making, and increased end-user productivity. Disadvantages are increased costs, management complexity, maintaining

第3章 关系数据库模型 本章介绍以下内容： 关系模型提供数据的逻辑视图； 关系是关系模型的基本组成； 关系是由行（元组）和列（属性）组成的逻辑结构； 关系在关系 DBMS 中是以“表”形式实现的； 关系数据库的操作符、数据字典和系统目录； 关系数据库模型如何处理数据冗余； 索引及其重要性。 在第 2 章已了解到，关系数据模型的结构和数据独立性使得我们能够检查模型的逻辑 结构，而无须考虑与数据存储和检索相关的物理模型。同时，我们也了解到可以通过实体 联系图（ERD）采用图形化方式描述实体和实体之间的联系。本章将学习关系模型逻辑结 构的具体细节，以及如何运用 ERD 设计关系数据库。 本章也将学习关系数据库的基本组成——“关系”如何适应“表”的逻辑结构。同时， 也会发现关系模型简单的重要原因之一是： 表既可看作是逻辑单元，也可看作是物理单元。 还将学习到数据库中各个独立的表与表之间是如何实现关联的。 在学习了表、表的组成和表的联系后，引入表设计的基本概念。由于表是关系数据库 设计中必不可少的部分，我们将学习到设计良好的表和设计粗劣的表的特征。 最后将介绍一些基本概念，为后续章节学习做准备，包括对不同类型联系的检查以及
