Data Languages and Imperative Languages: Easy to Code versus Easy to Use

• Data languages
• Produce some form of data structure used by an application.
• They are often used to represent configuration information.
• Example: sendmail
• Readability not typically one of their strengths.


• Imperative languages
• A step beyond data languages
• Actually executable, and so can contain statements, control constructs, etc.
• More useful in areas of program maintenance or integration
