The ABC Engineering (ABCE) has contacted you to create a conceptual model whose application will meet the expected database requirements for the company's training program. The ABCE administrator gives you the description of the training group's operating environment. ABCE has 12 instructors and can handle up to 30 trainees per class ● It offers five Advanced Technology courses, each of which may generate several classes. If a class has fewer than 10 trainees, it will be canceled. Therefore, it is possible for a course not to generate any classes Each class is taught by one instructor Each instructor may teach up to two classes or may be assigned to do research only Each trainee may take up to two classes per year Complete the table to define all of the entities and relationships. First one is done for you. Consider one of the relations as a composite relationship. ENTITY INSTRUCTOR RELATIONSHIP Teaches CONNECTIVITY 1:M ENTITY CLASS

Direct connections between the database and external entities are not allowed. This is one of the design ideas for data flow diagrams to take into account. What is implied by this advice?
By creating a data model, you may justify its use in database architecture.
No direct connections between external entities and the database are permitted. This is one of the data flow diagram design concepts to remember. What are the ramifications of this suggestion?
When it comes to database architecture, why do you believe entity relationship (ER) diagrams are necessary?

USE PAPER TO MAKE THE UML DESIGN For the example below Create the proper UML Design for your DB system. Assume the following scenario: Due to COVID-19 pandemic Your client has decided to design a database system to control the number of reservations on their resort mountain. The reservation system will take in consideration the following criteria. The maximum allocation based on the product type, take in consideration that the reservation type can be expanded in the future to more than these basic types. The reservation types are Tubing. Mountain. The Product Variant will store information such as the reservation type, the session that the product use such as: Session 1 Reservation. Session 2 Reservation. Session 3 Reservation. Session 3 in the Reservation require that both Session 1 and Session 2 to have availability in the system. The Maximum reservation limit depends on the minimum availability for the 3 Session in the system. Each day has its own reservation limit.…
. I want an ERP Diagram on following: Consider the following set of requirements for an Inventory database: • An INVOICE is written by a SALESREP. Each sales representative can write many invoices, but each invoice is written by a single sales representative. • The INVOICE is written for a single CUSTOMER. However, each customer can have many invoices. • An INVOICE may include many detail lines (LINE) which describe the PRODUCTs bought by the customer. • An invoice LINE references one PRODUCT, and a PRODUCT may be referenced in one or more invoice LINEs
How do you determine the level of normalization required for a particular database design?
Create a Crow’s Foot notation ERD to support the following business operations: A friend of yours has opened Professional Electronics and Repairs (PEAR) to repair smartphones, laptops, tablets, and MP3 players. She wants you to create a database to help her run her business.   When a customer brings a device to PEAR for repair, data must be recorded about the customer, the device, and the repair. The customer’s name, address, and a contact phone number must be recorded (if the customer has used the shop before, the information already in the system for the customer is verified as being current). For the device to be repaired, the type of device, model, and serial number are recorded (or verified if the device is already in the system). Only customers who have brought devices into PEAR for repair will be included in this system.   Since a customer might sell an older device to someone else who then brings the device to PEAR for repair, it is possible for a device to be brought in for…
Database design diagrams (DBDL) and entity-relationship (E-R) diagrams (ER) are both valid ways to depict a database's structure. For what reasons do you choose one tactic over another?
Please read this carefully and Draw an EER diagram for a database of a hospital following these requirements: create Four to five regular strong entities. A union One 1:1, one 1:N, and one N:M relationship – of which at least one relationship should be partial and one full. One overlap relationship and one disjoint relationship. Other notes: Do not emphasize on too many attributes for the entities. Two to three attributes for each entity will be enough. Make sure to include a primary key for each entity.
