1. Classic CDP (packaged CDP): All-in-one software that collects, unifies and distributes data. Useful if you don't yet have a robust data warehouse or if real-time streaming is your priority.
2. Composable CDP (reverse ETL): A modern, modular approach. Here, your existing data warehouse (e.g. BigQuery, Snowflake) serves as the basis. A lean activation tool synchronises the data directly into the end systems. This approach is often more cost-effective and prevents redundant data storage.
