DSPlogging

A simple interface to setup user, password, host and establish an DB engine

• features
  1. Setup an attribute engine contain an DB engine established by sqlalchemy
• ussage

from DSPutility.DSPdbInterface import dbintf
intf = dbintf(db_name='data', user='postgres', password='password', host='localhost', port='5432', vendor:str='postgresql')
# this will setup intf.engine as an instance of
# sqlalchemy.create_engine(f"postgresql://postgres:password@localhost:5432/data")

# after setup intf, you can do database operations through intf.engine, such as
intf.engine.connect()
