Visual paradigm tutorial class diagram code#
The getter and setter is OK, but the internal variable remains the old one, makes the code less consistent. The code creation creates a cosmetic hickup.While we can change easily the ERD to ‘this_is_a_short_remark_field’ and automatically get up to the meta class, our variable might be all over the place downstream the facade class. This is the class where you would implement your business logic Our sample column and troublemaker ‘this_is_a_very_long_remark_field_too’shows up in Since we started with PostgreSQL we didnt have to limit ourselves from creating very descriptive names though. VP helps on this when you select Oracle as DB and warns you if your name is getting too long. Oracle, even the latest version 11g, cannot handle identifier longer than 30 characters. Remember, we want to serve multiple DB’s with the same ERD without doing any modifications (other than selecting the DB type when creating the script) ORA-01918: user ‘myschema’ does not existĭue to Oracle creates the user in capital.The schema is not relevant to the classdiagramm or the created sourcecode, but it is important for the setup of our DB On the first sight only the number and float columns differ in the script. "fk_customername_customeraddress" varchar(36) NOT NULL,
"this_is_a_very_long_remark_field_too" varchar(255), "fk_customername_customeraddress" varchar2(36) NOT NULL,ĪLTER TABLE "customer_address" ADD CONSTRAINT "rel_customername_customeraddress" FOREIGN KEY ("fk_customername_customeraddress") REFERENCES "customer_name" ("customer_uuid") "customeraddress_uuid" char(36) NOT NULL,
