Databases Decompose the table into smaller tables that satisfy the normal forms. Make sure that your new tables have all of the same data as the original tables,Download the attached Excel spreadsheet. It has two different normalization problems, one in each tab. You can switch between problems by clicking the names “Problem 1” and “Problem […]
Clearly state your final relation schemas in 3NF. Explain what normal form is the relation in? What are the dependencies?
IT/BIFX 530 Applied Database Systems Homework #4: Normalization Consider the following relation that involves student data: Assume that only one professor teaches a class section, and professors teach in only one department. Suppose the following dependencies exist: What normal form is the relation in? Normalize it up to 3NF. Given the EMPLOYEES relation below: Emp_no […]
What is the difference between data, information, and knowledge? Explain in your own words how the data component relates to the hardware and software components of information systems.
Data and databases We learned about the role that data and databases play in the context of information systems. Data is made up of small facts and information without context. If you give data context, then you have information. Knowledge is gained when information is consumed and used for decision making. A database is an […]
Analyze the risks that can occur if any of the developmental or iterative steps of creating an ERM diagram are not performed.
Database Modeling and Normalization Imagine that you work for a consulting firm that offers information technology and database services. Part of its core services is to optimize and offer streamlined solutions for efficiency. In this scenario, your firm has been awarded a contract to implement a new personnel system for a government agency. This government […]
What ideas do you have for helping clinicians manage decision probabilities and provide at least one example.
Clinicians manage decision probabilities This week, we explored the knowledge component of the DIKW model. What ideas do you have for helping clinicians manage decision probabilities? Provide at least one example. Outcomes Utilize critical inquiry and judgment to evaluate the design, development, implementation, and outcomes of data management strategies for nursing and healthcare data. (PO […]
