Business requirements are the starting point for choosing a data storage system. Data engineers will use different types of storage systems for different purposes. The specific storage system you should choose is determined, in large part, by the stage of the data lifecycle for which the storage system is used.

The data lifecycle consists of four stages:

 Ingest

 Store

 Process and analyze

 Explore and visualize

Ingestion is the first stage in the data lifecycle, and it entails acquiring data and bringing data into the Google Cloud Platform (GCP). The storage stage is about persisting data to a storage system from which it can be accessed for later stages of the data lifecycle. The process and analyze stage begins with transforming data into a usable format for analysis applications. Explore and visualize is the final stage, in which insights are derived from analysis and presented in tables, charts, and other visualizations for use by others.
