Oracle Database in Docker and ODBC configuration

Create an Oracle database container in Docker in detached mode, access it inside the container, run sql commands to manage a sample employee table, and review port exposure and connectivity.

Map the Oracle container port to the host and connect from outside using the assigned port. Test connectivity and run queries to view users and create tables.

Create a new Oracle user in a dockerized instance by logging in as system, running docker exec, issuing create user and grant all privileges, then test and change the password.

Download the Oracle instant client for Windows 64-bit, gather the basic, sdk, and another package, extract them into a folder, and configure the odbc driver to access the Oracle database.

Set environment variables, install the Oracle ODBC driver, verify installation in the drivers tab, and configure the Oracle client and datasource name for Windows applications.

Configure tnsnames.ora in Windows by defining a tns alias with host and port, placing it in the instant client folder, and pointing an environment variable to the dns names file.

Inspect the registry under the local machine to see the driver registration, export or import the registration and connection details as needed, and note that uninstalling removes these entries.

Uninstall the oracle driver from the system, verify removal in data sources and the registry, and clean up the related environmental variables to complete the uninstall.
