Answer #1

Ans. 1.

Client tools implemented in 2-tier environment is proprietary which remains cautious on long term feasibility. It is difficult to scale in this scenario.

Business environments when placed on server with rapidly changing rules and regulations are not suitable since the database server has to handle the business logic which slows down database performance.

Ans. 2.

Statelessness in database processing can pose a problem when there are two related requests which tend to share a common variable. If the variable is not updated by the first request and the other request has to use the updated variable, then it wont be able to use it. It will have an old value and would cause inconsistency.
