Breaking Changes

Package Import Renamed to Lowercase (PEP 8)

The package directory has been renamed from ddcDatabases to ddcdatabases to follow PEP 8 naming conventions.

Before (v3.x):

fromddcDatabasesimportPostgreSQL, DBUtils

After (v4.x):

fromddcdatabasesimportPostgreSQL, DBUtils

All class names (PostgreSQL, MSSQL, MySQL, MongoDB, etc.) remain unchanged — only the package import name is lowercase.

Migration

Update all imports in your code:

# Find and replace
ddcDatabases → ddcdatabases

The pip install command is unchanged (PyPI is case-insensitive):

pip install ddcdatabases
