CLUE:
1. Create a database and its tables
2. Relate tables
- What is the function of a relationship?
- Validation, so that master table records are not easily deleted.
- Synchronization, so that when the master table is changed, the secondary table will also change.
- When DELETE CASCADE is active or "ON" (optional), then when a master table record is deleted, the data in the secondary table is also deleted.
3. Create a Java project
4. Create a main form
5. Create a doctor form (dialog)
6. Create a patient form (dialog)
7. Instantiate the doctor and patient forms
8. Connect the database to the form
- Library Input
- Connection Process
- Checking Server IP
- mysql User & Password
- Checking database
- Query Command
9. Testing

asked... I've followed the steps in the video but why can't I save? it appears like this...
run:
java.lang.RuntimeException: Uncompilable source code - cannot find symbol
symbol: class MysqlDataSource
location: class gage.paser
Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: jOptionPane.showConfirmDialog
at gage.paser.simpanActionPerformed(paser.java:96) at gage.paser.simpanActionPerformed(paser.java:96)
at gage.paser.access$000(paser.java:15)A1:
There is a missing part in the MysqlDataSource class, maybe after copying a block of code you forgot to change the configuration, try checking again on the page paser->class save. Edit/adjust the parts that are necessary.
Thanks and good luck, happy studying
