Relational Database Project

I have 11 tasks related to relational database. Knowledge of the subject is needed. I will post two examples of the project. Use 2-3 sources for each project and no plagiarism. First two projects by Saturday May 5th. (5pm EST) ----------------------------------------------------------------- 1. Look for an example of a one-to-one relationship, an example of a one-to-many relationship, and an example of a many-to-many relationship in a newspaper, magazine, book, or everyday situation you encounter. Describe the three types of relationships and explain your examples. For each example, name the entities and attributes, select the primary and foreign keys, and present it in the common shorthand method. All the answers should be in a Word document. Do not create these in Access. 2-3 pages 2. What are entity integrity and referential integrity? Why are they important for relational databases?
