- Transform the following entity relationship diagram into a relational schema.arrow_forwardTable 4-8 shows a portion of a shipment table for a large manufacturing company. Each shipment (identified by Shipment#) uniquely identifies the shipment Origin, Destination, and Distance. The shipment Origin and Destination pair also uniquely identifies the Distance. Question: a. Develop a diagram that shows the functional dependencies in the SHIPMENT relation. b. In what normal form is SHIPMENT? Why? c. Convert SHIPMENT to third normal form if necessary. Show the resulting table(s) with the sample data presented in SHIPMENT.arrow_forward# Question 2. Please select the correct statement(s) regarding keys in relational models. A. A candidate key is a key (super key) with a minimal set of attributes (cannot remove any attributes from this set, and the remaining one(s) still satisfy the key constraint). B. A candidate key is another term for key (super key) in relational models, and they have exactly the same meaning. C. One of the candidate key(s) is selected to be the primary key, and other candidate keys can be declared as UNIQUE. D. We can select multiple candidate keys to be multiple primary keys for a relation (multiple primary keys, not a primary key with multiple attributes). E. The attribute in a primary key does not accept NULL.arrow_forward

Draw the ERD Diagram to create relational model corresponding to the described Scenario. The loan office in a bank receives from various parties, requests to investigate the credit status of a Customers. Each credit request is identified by a Request ID and is described by a Request Date and Requesting party Name. The loan office also received results of credit checks. A credit check is identified By a credit check ID and is described by the credit check Date and the credit rating. The loan office Matches credit requests with credit check results. A credit request may be recorded before its result Arrives; a particular credit result may be used in support of several credit requests. Draw ERD for this Situation. Requirements: ER Diagram of system implemented in tool such as Sqlyog & Draw.io (Available online). Note: DRAW ERD ASAParrow_forwardLab 3: Normalization Assignment: Problem #11 from Chapter #6. (Be sure to note that this is PROBLEM and not REVIEW QUESTION). Normalize a set of data to 1st, 2nd and 3rd normal form by creating relational schemas, dependency diagrams and an Entity Relationship Diagram (crow’s foot notation). For this lab, complete problem #11 in Chapter 6. Be sure to complete each letter (a thru c) for the problem. The ERD for letter cmust be completed with the use of Microsoft Visio. Remember to include headers on all documents you submit to include a brief descriptive title, your name and a date. Question 11: Given the sample records in the CHARTER table shown in Table P6.11, do the following: 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.

Your answer should show all the three stages of normalization (1NF, 2NF and 3NF) by using the Database Design Language format (underline all primary keys, composite keys and use an * to indicate the foreign keys). State the component(s) that is/are removed from each Normal Form. Besides that, INF must be divided into repeating and non-repeating group relations. a) PatientID PatientName BloodID BloodType ExamDate DiseaselD DiseaseDesc HospitallD HospitalName 08/01/2020 D5001 08/01/2020 D3222 |11/11/2020 D5001 |11/11/2020 D7788 15/11/2020 D5001 12/12/2020 D3222 12/12/2020 D5001 Alice Hospital KL Hospital KL Hospital PJ Hospital SB Hospital SB Hospital KL Hospital PJ P7010 B001 B001 B001 A+ COVID-19 Н223 P7010 Alice A+ Diabetes H223 Alice Thomas P7010 A+ COVID-19 H881 P8888 B008 O- SARS H666 Penny Penny Julie P3000 B009 AB+ COVID-19 H666 P3000 B009 AB+ Diabetes H223 P4455 B008 0- COVID-19 H881 Table 1: Details of…arrow_forward
- A data model is a collection of data description constructs. The main purpose of a data modeling is to assist in the understanding of the meaning (semantics) of the data and facilitate communication about the information requirements. Discuss FIVE (5) evaluation criteria for a good data model.
