Your mParticle instance is comprised of multiple containers for data. The first level is the organization. To find your organization, you can look at the bottom left of your mParticle UI. In our example, the Organization name is Eric's Demo.
The next level is account. Depending on your organization's structure, you may or may not have multiple accounts. This information is found in the bottom left of the mParticle UI, too. In our example, the account is _Eric's Demo - Default Account.
The final level is the workspace. A workspace is the basic container for data in an mParticle account. When you first start using mParticle, your first workspace has been created for you, but you can add more at any time. In our case, the workspace is Base 2 Testing.
