Movie website wants to store information about movies andhas chosen you to help them Three steps: Requirements Analysis: Discover what information needs to be stored,how the stored information will be used, etc. Taught in course on systemanalysis and design Conceptual Database Design: High level description of data to be stored(ER model) Logical Database Design: Translation of ER diagram to a relationaldatabase schema (description of tables)(Database Schema). Physical Database Design: Done by the DB system.
Requirements For actors and directors, we want to store their name, a uniqueidentification number, address and birthday (why not age?) For actors, we also want to store a photograph For films, we want to store the title, year of production and type(thriller, comedy, etc.) We want to know who directed and who acted in each film. Every filmhas one director. We store the salary of each actor for each film An actor can receive an award for his part in a…
Translate the E-R diagram on page 1 (diagram) to database schema using MySQL Workbench (export as png or pdf). You can ignore the cardinalities on the ternary (Grant) relationship.
Interpret the database schema on slide 4. Draw the E-R diagram underlying this schema. No need to draw the attributes.

- The ______________ model is a simple but highly useful way to organize data into collections of two-dimensional tables called relations.arrow_forwardYou have been asked to design and implement a database for CTU, which includes 3 entities (tables), as follows: Students Faculty Courses Part 1 Create a Word document that includes the following: Identify at least 3 attributes for each entity, including the following: Student's entity should have an attribute for the program the student is enrolled in. Faculty should have an attribute identifying their rank. Properly identify all of the primary keys (use solid underlines). Create an entity relationship diagram (ERD) from the entities. You may use SmartDraw, Visio, Erwin, or even Word to draw the diagram. Take a screenshot (no need if you use Word), and insert it into the Word document. Part 2 Use Microsoft Access to implement the database that you designed in Part 1, and include the following: Create the Student, Faculty, and Course tables in Access. Add a few instances in each table. Create 2 queries for the following objectives: Find the student names for all students who are in the…arrow_forwardPlease 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.arrow_forward
- Produce an entity relationship diagram for a relational database that will be able to address the case study. It is your task to design a database that will adhere to good design principles.arrow_forwardProblem: Transform the table into 1NF, 2NF, and 3NF. Create a database diagram afterward. student_number firstname Database 035-20130-0205 | Mairo subject Advanced Systems Management Information 035-20130-0205 Systems Systems Analysis and 035-20130-0205 Design term lastname year 2016-2017 program | BSIT 2nd Eli 2016-2017 2nd BSIT Mairo Eli 2016-2017 2nd BSIT Mairo Eli 器arrow_forwardConsider the E-R diagram for a university database as shown in Figure 1. What is true about grade?(a) grade represents an entity set.(b) grade represents an attribute of takes.(c) grade represents an entity associated with takes.(d) none of the above.arrow_forward
- Develop a simple data model for a student database that includes student data, student contact data, student demographic data, student grades data, and student financial data. Determine the data attributes that should be present in each table, and identify the primary key for each table. Develop a complete entity relationship diagram that shows how these tables are related to one another.arrow_forwardCreate an ER model related to the following entities and relationships: Department, Student, Professor, Course, Section, Grade, Major. (For attributes inside each table, you only need to insert several reasonable attributes. No need to have a comprehensive list. For many-to-many relationship, you also need to insert one extra table to handle the many-to-many relationship. The final database design will have more tables than the number of entities listed above.) A given department can offer many courses. A given course can be offered by only one related department. A given course can have many related sections. A given professor can teach many sections. A given section can only be related to one course and taught by one professor. A given professor can have appointment with different departments A given department can have many professors. A given department can offer several majors. A given major can be offered by only one related department. A given student can have several majors. A…arrow_forward
