For Discussion…Assignment #3 – Work with Dream Home v. 1.0 to 2.0

1. Create your <name>DHV1 and <name>DHV2 as Needed and Ask for any Privileges you Want Added from Your DBA

2. Real-world Scenario – Update Current Database to New Schema and Reload Old Data Along with New Data

3. Bottom-Up Design focus on Attributes, Attribute Domains, Tables, Keys and Relations, … At DBMS Physical Layer

4. Top-Down Design focus on Information Models using ERD Driven by Concept and Requirements

5. Likely Will Encounter Both Scenarios

DreamHome v. 1.0Based on Earlier Edition of Connolly-BeggOriginal Source was Schema and Data for Ingres DBInstructor Adapted to Schema Generation (no changes required) and Data Loading (significant changes required) for MySQL

Example 6.24List the name of all clients who have viewed a property, along with any comments supplied.– Results the Same (NULL), but Order is Different from Book– Need to Adapt Query for this View a Bit

SELECT c.clientNo, fName, IName, propertyNo, commentFROM Client c, Viewing vWHERE c.clientNo = v.clientNo

Sam Siewert 9

Example 6.25For each branch office, list the staff number and names of staff who manage properties and the properties that they manage.– Results … Almost Identical other than Attribute names and B3 vs.

B003– Need to Adapt Query for this View a Bit

SELECT s.branchNo, s.staffNo, fName, IName, propertyNoFROM Staff s, PropertyForRent pWHERE s.staffNo = p.staffNoORDER BY s.branchNo, s.staffNo, propertyNo;

Sam Siewert 10

AdaptationMissing Table must be Added and Populated – Only Option

Attribute name changes – Handle with Updated Views or Alter Tables

Table name changes? – Updated Views (Stored Queries) or change Table names

Unload, Update Schema, Update Data, Reload?

Adapt from Existing v. 1.0 with SQL Script?
