• Dual Assessment of Data Quality in Customer Databases, Journal of Data and Information Quality (JDIQ), Volume 1 Issue 3, December 2009, Adir Even, G. Shankaranarayanan. (attached as PDF)
• Process-centered review of object oriented software development methodologies, ACM Computing Surveys (CSUR), Volume 40 Issue 1, February 2008, Raman Ramsin, and Richard F. Paige. (attached as PDF)

Write a two to three (2-3) page paper in which you:

1. Recommend at least three (3) specific tasks that could be performed to improve the quality of datasets, using the Software Development Life Cycle (SDLC) methodology. Include a thorough description of each activity per each phase.
2. Recommend the actions that should be performed in order to optimize record selections and to improve database performance from a quantitative data quality assessment.
3. Suggest three (3) maintenance plans and three (3) activities that could be performed in order to improve data quality.
4. From the software development methodologies described in the article titled, “Process-centered Review of Object Oriented Software Development Methodologies,” complete the following.
   1. Evaluate which method would be efficient for planning proactive concurrency control methods and lock granularities. Assess how your selected method can be used to minimize the database security risks that may occur within a multiuser environment.
   2. Analyze how the method can be used to plan out the system effectively and ensure that the number of transactions does not produce record-level locking while the database is in operation.

Your assignment must follow these formatting requirements:

• Be typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

• Prepare database design documents using the data definition, data manipulation, and data control language components of the SQL language.
• Describe the basic mechanisms for accessing relational databases from various types of application development environments.
• Explain the key principles of data security and identify data security risk and violations in data management system design.
• Use technology and information resources to research issues in the strategic implications and management of database systems.
• Write clearly and concisely about topics related to the strategic planning for database systems using proper writing mechanics and technical style conventions.
