Modifying Design PropertiesModifying Design Properties

• To modify design properties, you can use either:

– Property dialog box– Shows you the commonly used

properties for the type of object selected

– Property palette– Shows ALL the properties for the

selected object

• Icon to toggle between dialog box vs. palette display

Setting a Default to SYSDATESetting a Default to SYSDATE

To have a field default to the current date, in the properties palette:

• Set Default to SYSDATE

• Set Derivation Expression Type to “Function Call”

• Set Server Derived to “Yes”

• SAVE!

Use the Design Editor to view your HOLLYWOOD database design (server) model:

• Use property palette AND property dialog box to examine properties of the COPIES table

• Use property palette AND property dialog box to examine properties of a field in the COPIES table

• Get comfortable with the toggle between these two property displays

• Get comfortable with the toggle between these two property displays



Use Design Editor to make the following modifications to your HOLLYWOOD server model:

• Re-order fields to be in this order . . .– # primary key fields

– * mandatory fields

– o optional fields

. . . By using the table properties dialog box, Columns tab, select a column name and use the screen arrows

Table APITable API

By generating the Table API:

• We generate needed procedures and triggers to go with the database, e.g.:

– PL/SQL logic in the server that processes and validates data before inserts, updates, and deletes are executed on database tables

–i.e., Logic to enforce referential integrity

– Code to operationalize “server-derived” fields
