Worked on enhancing the oracle-livelabs/database repository by updating documentation for the Autonomous Database (ADB) connection setup with Edition-Based Redefinition. Focused on improving onboarding accuracy and lab reproducibility, the work involved revising Markdown files to update download links, file names, and image references, transitioning from 'ebrlabs' to 'ebronline.zip'. Additionally, metadata such as author and last updated information was refreshed to ensure current and accurate lab setup details. No code changes were released, as the primary emphasis was on technical writing and documentation skills, ensuring that users could reliably follow the updated onboarding process for ADB-based lab environments.
