1 point Information is data processed into a meaningful form. * True False An instance is the data that you 1 point are interested in capturing about an entity. * O True O False 1 point Cost and complexity are just two of the disadvantages of database processing. * O True False 1 point A constraint is a rule that cannot be violated by users of a database. * O True O False 1 point Knowledge is the capacity to recognize what information would be useful for making decisions. * O True O False Hoffer developed the relational 1 point data model during the 1970s. * True False 1 point Any create command may be reversed by using a remove command. True False 1 point The concept of redundancy increases the risk of * inconsistent data. True False 1 point An employee's name, address, date of birth, and social security number are all examples of descriptors. * O True O False It is apparent that the objective 1 point of data modeling is to document business rules about data flow processes. * O True False 2 points An entity is a person, place, object, event, or concept in the user environment about which the organization wishes to maintain data. * O True False 2 points Database programming languages receive all application requests and translate them into the complex operations required to fulfill those requests. * O True O False 2 points The database management system shows much of the database's internal complexity to the application programs and end users to support in the process of decision making. * O True O False Entities are attributes that 2 points describe the characteristics and the set of relationships that links the data found within * the database. True False 2 points Business rules logic includes such activities as data validation and identification of processing errors. O True O False 2 points An advantage of a database system over previous data management approaches is that the database system is considerably less complex. O True O False 2 points A disadvantage of the database management systems is that it increases the risk of data security breaches. * True False 2 points To improve the performance of a system it is important that file redundancy continues to be applied to establish relationships between the information. * O True O False The traditional file processing 2 points approach allows for extensive data sharing as each application shares data files. * True False The external schema contains 2 points a subset of the conceptual schema relevant to a particular group of users. * True False 2 points A database is a logically connected set of one or more fields that describes a person, place, or object. * O True False 2 points The data structures include data organized in the form of tables with columns and rows. * True False 2 points As the data is entered into a form and saved, it is apparent that it is stored in the underlying database as knowledge. * O True O False
