Answer:
Explanation:
The underlined traits in the ER chart speak to essential key since they remarkably recognize the quality
(a)
(I) The level of the given relationship is 2 i.e it is a parallel connection among Book and Publisher. It is a one to numerous relationship from distributer to book in light of the fact that a distributer can distribute any number of books however a book will have only one publisher,so the cardinality will be 1 to 1..* (one to many)
(b)
(i) The degree of the given relationship is 2 i.e it is a binary relationship between Author and Book. It is a many to many relationship from Book to Author a book can be written by one or more authors and an author can write more than one book, so the cardinality will be 1..* to 1..* (many to many)
(c)
(i) As mentioned in part (b), the degree of given relation is 2 and cardinality is many to many (1..* to 1..*)
(d)
(i) The degree of the given relationship is 1 i.e unary relationship. It is a many to many relationship because one book can belong to any sets and a set can have any number of books, so cardinality is 1..* to 1..* (many to many)

Explanation:
Data mining is referred as an automated processing tool used for sorting and analyzing enormous data and information which indeed are ``aimed towards effectively identifying trends and patterns and establishing relationships to solve business problems and generate new opportunities. Furthermore data mining techniques also helps to predict what’s going to happen in the future and act accordingly to take benefit of forthcoming tendencies.
Data mining is applied to a variety of large-scale data-processing activities such as collecting, extracting, warehousing and analyzing data. It also includes decision-support applications and technologies such as business artificial intelligence and machine learning and is used in varied areas of business research such as product development, sales and marketing etc.
Data mining is for taking advantage of data to predict
;
- Mathematical algorithms, and, data are used for predictive analytics. One can capture information, and, use it to model sales pattern, trends, and, customer behaviour
- Data mining uses algorithms to extract, and, analyze information; discover hidden patterns
- It uses data patterns, and, is thus closely tied to machine learning
- Historical & current information is used to predict future trends
Data mining can be used for the following:
- Data mining in gas & oil operations - Mining data in gas & oil operations involves committing to key technologies, and, processes; and, embracing new ways of thinking & problem-solving. Firms can use exploratory data analysis, modelling techniques & model development; approaches to put models into production
- Big data - Performance computing & advanced analytics
- Magic Quadrant - Evaluate 16 vendors to identify the right ones
- Heavy reading, network analytics - Optimize network; evaluate network performance; provide targeted marketing; fine-tune capacity.
Assuming no options are provided, Jeremy would do well to create a weekly progress report, detailing what the company has accomplished during the week, and what remains to be accomplished. The report should be goal-based with defined deadlines, and clear explanations on what has been done and what remains to be done, and should be organized by the various aspects of the project (accounting, marketing, etc). This report will help keep his team conscience of their role within the larger project, what they have accomplished thus far, and what still needs to be done.
