4. The Future of Work
Rand Corp reports that most secure jobs in the US involve the adaption of new technology to solve business problems in innovative ways*
Databases have changed the world!!!!
Diskman to iPod
Google “top skills employers look for”
Google “top skills needed in business”

5. The Characteristics of Databases
The purpose of a database is to help people track things of interest to them.
Data is stored in tables (relations), which have rows (records or tuples) and columns (fields or attributes) like a spreadsheet.
A database may have multiple tables, where each table stores data about a different thing.
Each row in a table stores data about an occurrence or instance of the thing of interest.
A database stores data and relationships.
Can keep track of things on paper; in a filing cabinet. What are the limitations?
Can keep track of things electronically in files or a spreadsheet. What are the limitations?
What if I kept information about all my music in one of these formats?

6. Why not just use a spreadsheet?
CSIS114 Lab Revisited
Assignments > In-Class Activities > DB vs SS > Vet Clinic SS

7. Vet Clinic Spreadsheet
Add a record for Sara Craver’s (client #17) new dog named Peaches who had an appointment on 9/16/05 at a charge of $50.
Note: do it the best way you see fit!

8. Adding a record for Sara Carver's new dog – which is the best (least limiting) strategy?
Replace the name of the dog, visit, and amount values in record 17 with the new values.
Add a blank record right under record 17, and put in just the new dog, date and charge values.
Add a blank record right under record 17, put in the new dog name, date, and change values, then copy all other fields of record 17 data into the new record.
Start another sheet in the workbook and put the new record there.

9. SS - Data Validation In cell G14, type in the zip code 01237
In cell H13, type in the following for phone number:
In cell K13, type in the following date 12/35/2004
In cell L12, type in for the amount (this is a typo, the value should be 30.50)

10. Database Benefits
Databases allow us to organize data in a structured way
Eliminate (or at least significantly reduce) data duplication
Database user interfaces help Prevent Data Errors

11. Account Balances
Becker's keeps client accounts on a second sheet named accounts.
Notice that the Client Id Field is used to link the records on the two sheets.
But is there really a “link”?
How would you accomplish the tasks described in the next questions?

12. What is the best procedure to determine the current balance for all the clients?
For each client use calculator to subtract the payment amounts from the visit amount
Sort accounts by client number, subtotal with sum on the Credit/Debit field.
Filter for all the Payments and form their sum, then filter for all the visits, form their sum, subtract the sum of payments from the sum of visits.
Compute the sum of the Credit/Debit field.
This task could be accomplished more efficiently in a database.

13. Vet Clinic Spreadsheet
Why is this not a good solution?

14. Database Benefits
Databases allow us to organize data in a structured way
Eliminate (or at least significantly reduce) data duplication
Database user interfaces help Prevent Data Errors

15. Components of a Database System with SQL

16. Applications, the DBMS, and SQL
Applications are the computer programs that users work with.
The Database Management System (DBMS) creates, processes, and administers databases.
Structured Query Language (SQL) is an internationally recognized standard database language that is used by all commercial DBMSs.
