Hi,
I'd like to introduce ETL Helper. It is a library that we developed in the=
British Geological Survey to simplify transfer of data between databases.=
I hope that it will be useful to members of this list. I would also be v=
ery grateful for any feedback.
https://pypi.org/project/etlhelper/
The aim of ETL Helper was to allow users with little Python experience (sci=
entists and DBAs) to be able to access data. The library handles importing=
drivers, formatting connection strings and cursor management to reduce the=
amount of boilerplate code required to run a query.
It uses DBAPI2 features to provide a consistent interface for Oracle, Postg=
reSQL, MS SQL Server and SQLite databases by wrapping around the underlyin=
g drivers (cx_Oracle, psycopg2, pyodbc, sqlite3) and abstracting away diffe=
rences (connection string format, error names, execute_batch vs executemany=
).
We have an internal Oracle database at BGS, so etlhelper includes a script =
to install Instant Client onto Linux machines.
We have been using the library internally for nearly two years so I am conf=
ident in the code, however it would be great to have comments from Python d=
evelopers who have greater expertise than we do.
Cheers
John
