Contexte et remarques
Create the directories c:\tutorial, c:\tutorial\hq, and c:\tutorial\field.
From the c:\tutorial directory, run the following command to create the consolidated database (hq):
dbinit -dba DBA,sql hq.db
Connect to the consolidated database (hq) from Interactive SQL.
dbisql -c "UID=DBA;PWD=sql;SERVER=server_hq;DBF=c:\tutorial\hq.db"
Execute the following statements to create two tables in the consolidated database (hq):
CREATE TABLE SalesReps ( rep_key CHAR(12) NOT NULL, name CHAR(40) NOT NULL, PRIMARY KEY ( rep_key ) ); CREATE TABLE Customers ( cust_key CHAR(12) NOT NULL, name CHAR(40) NOT NULL, rep_key CHAR(12) NOT NULL, FOREIGN KEY ( rep_key ) REFERENCES SalesReps (rep_key ), PRIMARY KEY (cust_key) );
The following figure shows the consolidated database (hq) schema for the tutorial:
Each sales representative is represented by one row in the SalesReps table.
Each customer is represented by one row in the Customers table.
Each customer is assigned to a single sales representative, and this assignment is built into the database as a foreign key from the Customers table to the SalesReps table. The relationship between the Customers table and the SalesReps table is many-to-one.
In the SalesReps table, there is a row for each sales representative that works for the company. The SalesReps table has the following columns:
In the Customers table, there is one row for each customer that does business with the company. The Customers table includes the following columns:
Execute the following statements to add sample data to the SalesReps and Customers tables:
INSERT INTO SalesReps (rep_key, name) VALUES ('rep1', 'Field User'); INSERT INTO SalesReps (rep_key, name) VALUES ('rep2', 'Another User'); COMMIT; INSERT INTO Customers (cust_key, name, rep_key) VALUES ('cust1', 'Ocean Sports', 'rep1' ); INSERT INTO Customers (cust_key, name, rep_key) VALUES ('cust2', 'Sports Plus', 'rep2' ); COMMIT;
Execute the following statements to confirm that the tables were created:
SELECT * FROM SalesReps;
The above query returns the following data from the SalesReps table:
SELECT * FROM Customers;
The above query returns the following data from the Customers table:
