All of you must be familier with human resources system (employee database). Soplease design database for a human resources system that at least has 4 entitiesinvolved and for the 4 entities please do the following:a. Create the tables that conform to 3NF.b. Draw the Crow’s Foot ERD to reflect the dependency and relationshipdiagrams;c. For all entities/tables created please write the MASTER and TRANSACTIONdata accordingly!d. Use SQL commands to to do selection which involve 1 table, 2 tables, and 3tables.
I want to create logical database design: 1. Normalize the relations to at least third normal form (3NF) using proper standard E-R diagram notation. Provide the appropriate relational schema reduction. 2. Identify the primary and foreign keys for each relation (using appropriate notation). Maybe either list the primary and foreign keys or generate a schema diagram??? 3. Identify and describe any indexes needed to speed up searches on non-key attributes – can you explain it too? So I would understand why you come up with the answer please? 4. Identify and describe unique, conditional (check), non-null, referential integrity, or other constraints needed to guarantee the integrity of the database. 5. Describe the set of business or workflow rules applicable to your project. Next, describe at what point in the workflow you will implement the business or workflow logic and the justification for doing so.Below are my conceptual design.
7. In the context of database design, consider the following scenario: There is database table that contains columns for employee ID, employee name, department, department location, and project details. Upon analyzing the table, you notice that there are multiple rows with the same employee name, department, and department location, but different project details. Based on this scenario, which of the following best describes the normalization process that should be applied to improve the database design? A) Split the table into two: one containing employee ID and employee name, and the other containing department, department location, and project details. B) Combine all columns into a single table to reduce redundancy. C) Normalize the database to the third normal form by creating separate tables for employee details, department details, and project details, and establish relationships between them. D) No action is required as the table already follows the normalization principles.
