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.
