Question:

I. Executive Overview: Provide a general, high-level overview outlining the key issues, high-level recommendations, and important considerations to remediate performance and latency concerns.

II. Performance Tuning a) Describe what types of tuning should be done to enhance database performance and how database transaction might be replicated to other database servers. b) Defend your recommendations using relevant research and explaining how you formed your conclusions.

III. Query Design

a) Explain the application of query design and how queries can be made more efficient, while attending to issues relating to joins, sub-queries, and sorting. Additionally, you should explain issues that could arise from select, update, and delete queries. Be sure to cater your explanation to the specifics of the scenario case.

b) Consider how refining the selection criteria could enhance the efficiency of database queries. In other words, how would you propose attending to the issues relevant to queries highlighted in the scenario, and why?

c) Design database queries for optimum performance for the scenario, and defend your conclusions.

IV. Data Duplication and Redundancy

a) Explain database normalization in terms of its use and purpose for the scenario. In other words, provide an explanation of database normalization and other techniques that can be utilized to reduce data duplication and redundancy within the scenario database.

b) Defend the selection of techniques explained as being potential solutions for data duplication and redundancy within the scenario database.

V. Multiple-User Access Issues and Errors

a) Develop a strategy that will allow for troubleshooting run-time and application errors.

Describe some common errors that are seen in commercial database systems and propose mitigation.

b) Describe what high-level methods could be used to enhance multi-user access within databases in general. Create a set of database design specifications that would provide for multi-user access for the property tax payment and information system. The design specifications should provide details on concurrency control, record locking, and user security, and they should also provide room for future database growth. Discuss the impact of these changes and what resources would be required.
