Describe a situation where you needed to decide between using a single database for multiple microservices or having separate databases for each service. What factors influenced your decision, and what were the trade-offs?

``` Evaluate the domain boundaries and bounded contexts, opting for separate databases to minimize tight coupling while considering operational overhead and potential data duplication. Scenario Pressure: If legacy systems are involved, how would you approach migrating to a microservices database structure? Depth Trigger: Discuss the potential impact on service performance and data access speeds. ```
