What are the benefits and drawbacks of continuing to use the legacy database?

To prepare for this Discussion,

Identify a legacy system in a business or government agency (federal, state, or local). Many online sites can be used to identify existing legacy systems. With these thoughts in mind, respond to the following prompts:

1-Should the agency continue using a legacy system? What are the benefits and drawbacks of continuing to use the legacy database?

2-Discuss the needs of the agency and consider the benefits and limitations of each database model.

With these thoughts in mind, make a recommendation to keep the existing system or to upgrade to a new design based on your answers to the questions above.
