Overview of the lab domain

The lab will focus on building an account CRUD service for a user.

The account contains:

• accountId (String)

• balance (Double)

• ownerFirstName (String)

• ownerLastName (String)

• activeFlag(Boolean).

As the course progresses, each lab will aim at creating an outcome, parallel to, the discussed example in this lab account-service.
