Study Notes

CRUD Operations

CRUD stands for Create, Read, Update, Delete, representing the four basic operations for managing data in a database.
Create is the operation used to insert new data into the database.

Read Operation

The Read operation retrieves or accesses existing data stored in the database.

Update Operation

Update is the operation used to modify existing data in the database.

Delete Operation

The Delete operation removes or deletes existing data from the database.

Type 1 JDBC Driver

The Type 1 JDBC driver is also known as the JDBC-ODBC Bridge driver.
It is mainly used when an application needs to connect to databases that only support ODBC.

Requirements for Type 1 Driver

The Type 1 driver requires an ODBC driver for each database that you want to access, necessitating separate installations for each.

Limitations of Type 1 Driver

The Type 1 driver is not recommended for production use due to performance inefficiencies and reliance on ODBC.

Function of Type 1 Driver

The Type 1 driver acts as a bridge between JDBC API calls and the ODBC API, translating JDBC calls into ODBC calls.
