Data Sharing
In the previous chapter, we looked at how the data stored in Amazon Redshift can be consumed. But imagine that, in a large company such as our GreatFin example, every line of business (LOB) produces and consumes its own data gathered from multiple channels. For a company to be truly data-driven, the data silos need to be broken and there needs to be an easy way to share data across all LOBs, without the need to physically move the data around as duplicate copies.
First, we will look at how you can share data inside your organization, from a data lake on S3 as well as from the data warehouse we built on Redshift.
In this chapter, we will look at the following key topics:
- Internal data sharing
- External data sharing
