Relational Schema and Normalization

 

 

Part 1
1. Write the relational schema and draw the dependency diagram for the table structure. Make sure that you
label all dependencies. CHAR_PAX indicates the number of passengers carried. The CHAR_MILES entry is
based on round-trip miles, including pickup points. (Hint: Look at the data values to determine the nature of the
relationships. For example, note that employee Melton has flown two charter trips as pilot and one trip as
copilot.)
2. Decompose the dependency diagram you drew to solve part 1 (Problem 11 in the text) to create table
structures that are in 3NF and write the relational schema.
3. Draw the Crow’s Foot ERD to reflect the properly decomposed dependency diagrams you created in the
second part of this problem. Make sure the ERD yields a database that can track all of the data shown above.
Show all entities, relationships, connectivities, optionalities, and cardinalities.
Part 2: Write a summary paragraph outlining the importance of normalization to large databases such as
HCUP or HEDIS.

Sample Solution

The Progession of Poems Adrienne Rich and Paulo Freire share a common theme in transition and society. Both are talking about the transformation of society and the relationship people have in writing. Freire talked about the way teachers teach the students, and there is no contradiction as they are sitting there waiting for information. Rich uses a similar theory in her essay “When we die” where she talks about society and how it is suppressed. Both have similar theories, but they have different ways to express their arguments. “When doing mechanical language training in a mechanical way, students can train like well-trained parrots.When stimulating, students can repeat the whole thoroughly. :: ^ In addition to the received teaching materials, students must take the first lesson to apply what they remember or what they are doing to the communication context designed by the classroom group. In the mid-seventies This approach was proposed due to dissatisfaction with structural and behavioral language teaching methods, which is currently widely used in textbooks not only in the west but also in our Libya school training centers. In addition to secondary school textbooks, most petroleum departments and bank training centers apply this method to English classes. Talk about playing that language! This is a wonderful poem that teaches students the flexibility of language. The interesting thing about this poem is that students can understand what is going on, even if there are meaningless words like “vorpal” or “uffish”. A monster named “bandersnatch” captures the imagination of the student. Lewis Carroll uses portmanteaus to create new words – this is an interesting challenge to have your own students try. This is a poem that I like to make my students bit me. I handed it to them and waited. My student sat for a while, and I will assign a burn about it. A few minutes later, the students showed a reaction “Oh”. Candlelight is a rather annoying symbol in literature, but I always like Edna St. Vincent Mirei to overturn our expectations for this poem. The students said they were proud of themselves, sadness, full of hope, and a little lost. I like 4 rows of packaging very much!
