Details

One paragraph explaining the functionality which is represented by this graph. What the main flow is and what is its purpose.

Driver

The global driver entry point registered with database/sql. Its sole responsibility is to parse the DSN and create a Connector.

Related Classes/Methods:

  • driver.go

Connector

Holds immutable connection configuration. Its purpose is to create new Connection objects for the connection pool on demand.

Related Classes/Methods:

  • driver.go

Connection

Represents an active database session. It is the central hub for managing transactions, preparing statements, and executing direct queries.

Related Classes/Methods:

  • conn.go

Transaction

Implements the driver.Tx interface, managing the state of a database transaction and providing Commit and Rollback methods.

Related Classes/Methods:

  • tx.go

Statement

Represents a prepared SQL statement (driver.Stmt). It manages query execution, parameter binding, and result set iteration.

Related Classes/Methods:

  • stmt.go

C Interop (ODPI-C) Layer

The low-level abstraction layer that uses CGo to communicate with the Oracle ODPI-C library. It translates Go calls into C function calls.

Related Classes/Methods:

  • orahlp.go
  • z*.go

Data Type Conversion [Expand]

A utility component responsible for converting data between Go native types (e.g., string, int, time.Time) and Oracle's internal data types.

Related Classes/Methods:

  • data.go
  • lob.go
