The JDBC architecture specifies how Java applications connect with the JDBC API and Database drivers to execute database operations including connection, querying and updating a relational database.
2-Tier and 3-Tier Architecture
Two-Tier Architecture
- Java application communicates directly with the database.
- Uses JDBC API and JDBC Driver.
Java Application → JDBC API → JDBC Driver → Database
Use Case: Standalone apps or simple desktop applications.
Three-Tier Architecture
- Introduces middleware as an application server positioned between the client and the database.
- The client application sends requests to middleware which then uses JDBC to interact with the database.
Java Application → Middleware (App Server) → JDBC API → JDBC Driver → Database
Use Case: Enterprise-level web applications require scalable solutions to meet their security demands and business logic requirements.
