96) Database maintenance is typically the longest step of the database development process.

 

 

97) Characteristics of the structure of the database are generally changed during the implementation phase of the database development process.

 

98) Prototyping is a type of rapid application development.

 

 

99) In prototyping, implementation and maintenance activities are repeated as necessary until the product is correct.
