Database table definition:

CREATE TABLE customer
(
   id INTEGER NOT NULL PRIMARY KEY,
   fname VARCHAR(50),
   lname VARCHAR(50) NOT NULL
);

INSERT INTO customer VALUES ( 101, "John", "Calagan" );
INSERT INTO customer VALUES ( 102, "Mike", "Torn" );
INSERT INTO customer VALUES ( 103, "Omer", "Winston" );

The "shop.sch" schema file:

customer^id^258^4^1^
customer^fname^13^50^2^
customer^lname^269^50^3^

Form definition file "form1.per":

SCHEMA shop
