  10. What is Data? Computer Human • Facts and statistics collected together for reference or analysis • The quantities, characters, or symbols on which operations are performed by a computer, being stored and transmitted in the form of electrical signals and recorded on magnetic, optical, or mechanical recording media • Things known or assumed as facts, making the basis of reasoning or calculation

  11. Announcements • No Lab this week! • Read Chapter 1 - pp. 1-23 • If you have any concerns about anything, Talk to me sooner rather than later!

  12. End of Class 1

  13. What kind of data do you have? • Class Schedules • Contacts • Names • Phone Numbers • Address • Email • Food Specials • Movies, Music Collect

  14. How do you store data? • Paper • Post-it Notes • Excel • iTunes • Address Book

  15. List Activity • Get in groups of 3 people • Nominate one person as the scribe, and have them type your list • Make a list of all the data you store and how it is stored

  16. Problems with Lists • Redundancy - In a list, each row is intended to stand on its own. As a result, the same information may be entered several times. • For Example: A list of Projects may include the Project Manager’s Name, ID, and Phone Extension. If a particular person is managing 10 projects, his/her information would have to be entered 10 times.

  17. Problems with Lists • Multiple Themes - In a list, each row may contain information on more than one theme. As a result, needed information may appear in the lists only if information on other themes is also present. • For Example: A list of Projects may include Project Manager information (Name, ID, and Phone Extension) and Project information (Name, ID, StartDate, Budget) in the same row

  18. List Modification Issues • Redundancy and multiple themes create modification problems: • Deletion problems • Update problems • Insertion problems

  19. List Modification Issues

  20. Types of Data • Objects that contain data have an associated data type that defines the kind of data. The following objects have data types: • Columns in tables and views. • Parameters in stored procedures. • Variables. • Transact-SQL functions that return one or more data values of a specific data type. • Stored procedures that have a return code, which always has an integer data type.

  21. Types of Data • Assigning a data type to an object defines four attributes of the object: • The kind of data contained by the object. • The length or size of the stored value. • The precision of the number (numeric data types only). • The scale of the number (numeric data types only).

  22. One week down 15 to go! • Next week • Big Data and why Data base • First Lab • First homework due!
