basis Ethernet Router Network Hot spot Backup Peer to Peer 11 DSL 2 In a relational database each row Has a primary key and each column has a unique name 3 A data is a collection of related records stored on storage media such as a hard disk or optical disc 4 A allows users to access and analyze any view of the database data 5 A n stores data in objects 6 Object oriented and object relational databases often use a query language called to manipulate and retrieve data 7 Occasionally a database can be damaged or destroyed because of 8 A n is a collection of data organized in a manner that allows access retrieval and use of that data 9 In managing a company s database the database requires a technical inside view of data 10 A major weakness of a lot of file processing systems is that They have redundant data and they isolate data 11 Because a data dictionary contains details about the data in a database File Hypercube OODB OQL All of the above Database Administrator some call it Metadata 12 The developer of a relational database refers to a record as a n Chapter 11 1 A is a small text file that a Web server stores on a user s computer 2 A UPS connects between a computer and a
