By filling the database with test data, we can begin to determine if the tables are normalized correctly, need changes to the keys and foreign keys, or new bridge tables are needed to correctly output the data. It is also at this point that we test to ensure that data types match and all entities are of the proper format. Although Change Request No. 3 seems fairly simple, it will bring to light any issues that might have been encountered while interpreting the tables from the ERD Diagram. It is not uncommon for changes to be needed to the database after it has been created from the ERD. Moreover, now is the best time to catch these issues before the system is fully functioning making it much more difficult to make certain changes. Creating ERDs According to Kroenke and Auer (2010) there is an ERD standard, albeit very loosely practiced. The diagrams use combinations of rectangles and diamonds. Entity classes are shown using rectangles, relationships are shown using diamonds, the maximum cardinality of the relationship is shown inside the diamond, and the minimum cardinality is shown by the oval or hash mark next to the entity. The name of the entity is shown inside the rectangle and the name of the relationship is shown near the diamond. As said in the earlier section, Process of Using Entities and Attributes, the process for using the entities and attributes for the fleet truck maintenance

However, Diagnostics Services has been operating without a sales manager. They do have six sales representatives,
In insertion sort, the best case is not quadratic because it only has to verify each entry once since it would have nothing to insert. The algorithm would just read through the array once and see that it is already sorted. Selection sort must check each entry twice to verify that the array is correctly sorted in the best
Write an unambiguous definition for each attribute. Then, redraw PE Figure 7-1 by placing the six (and additional) entities in this case on the diagram along with their associated attributes.
First our team will talk about how Microsoft Access was used to create these tables by Huffman Trucking Database. Then how we used the tables with made up information to be tested on. Then on how we used forms in the maintenance database system. While the creation of relationships and normalization is explained in the process of using queries to search the database (University of Phoenix, 2007).
Huffman Trucking is a major transportation company that has four facilities around the country. The organization
To begin replication of Cacioppo & Petty's Study 1 with random scores, I opened IBM SPSS Statistics 24 (SPSS) located in the IBM SPSS Statistics folder in the Start Menu (this folder will only be present if the computer has a license for SPSS software. Psychology Lab in Strauss Hall is a great place to use computers with SPSS software). Allowing time for the software to load, I went to www.random.org (random.org) in the internet browser, Google Chrome. Random.org is where I created all the random scores I needed to replicate Caioppo & Petty's Study 1.

3. Describe at least two examples of common errors in entity relationship modeling. If possible, provide a graphical illustration of the problems and solutions. List some questions the designer should consider before designing the models so that these errors can be avoided.
From the list of entities and discussion of relationships create a fully-attributed Entity Relationship Diagram (ERD) to model the functional requirements of the Tarleton Gaming Solutions database. Because your client’s background in database design is quite limited provide a detailed explanation and justification of the ERD you are proposing. This includes but is not limited to the choice of entities, attributes, primary and foreign keys, relationships, and cardinality.

It all started with a man that goes by Malcolm McLean who was born in 1913 in Maxton, North Carolina. Malcolm started out by pumping gas at a local gas station to where he saved up enough money to buy him a truck. From there he created McLean Trucking company, involving his own family members and as Malcolm as one of the drivers they hauled empty tobacco barrels as their first cargo. Since his only pick-up truck in 1934 to 1770 trucks and 32 terminals in 1956, McLean Trucking became the second largest trucking company in the United States, and the first trucking company to appear on the stock exchange. Though all of his success early on, Malcolm sold his interest in his company and wanted to try something different. The idea of transporting trucks on ships during World War II was around but Malcolm
