Validation rules are useful to prevent data entry errors in databases. True False Which one of these is not a good guideline to follow when creating tables in a relational database? Design first, create tables later Name tables systematically, using conventional \"tbl\" prefixes Use mnemonic names for data fields Assign at least 50 characters to each text field Use consistent data types for primary and foreign key fields The purpose of an input mask is to: Disguise data when they are first input into a database Transform data from alphabetic to numeric formats Help users avoid data entry errors Hide sensitive data such as passwords onscreen In QB, an appropriate field in which to use a default value would be Customer phone number Employee SSN Date on a check Number of items on an invoice both c and d A querie is used to extract information from a database True False In a database, like Access, the terms \"size,\" \"data type,\" and \"input mask\" are mostly closely associated with: A table A record A data field A database An agent It would be appropriate to store zip codes as a field type "text" as opposed to "number" True False Which of the following is not an example of a form for entering data in QuickBooks?

Unit cost of an item Extension amount Sales tax Grand total all of these are calculated fields Manual forms, in terms of database form design, are: Rarely useful Used to guide the development of electronic forms Used to collect information electronically Self-calculating Difficult to translate into computer forms if they are multi-part Reports enable users to: Change information in the underlying database tables See summarized output of database information in a familiar, usable form Limit the distribution of database information Re-format input masks Test validation parameters
