Install the SQL Importer in Hull and connect your database. Hull can query your database for updates as often as you like (every 3 hours by default). Each query will be displayed in the list of jobs.
Hull will write your SQL data into Profiles as Users, Accounts, Attributes, and Events to map and sync to all your tools.
Fork, extend, and host the SQL Importer yourself. All Hull integrations are open source. View the SQL Importer repo on GitHub.
