Question

Based on the ERD below, display all columns in the JOB table for those job descriptions that have both analysts and engineers within the description name. (Hint: You will use a “Like” phrase.)

This image illustrates a relational database schema with four connected tables: JOB, EMPLOYEE, ASSIGNMENT, and PROJECT. 1. **JOB Table:** - **Primary Key:** - JOB_CODE - **Attributes:** - JOB_DESCRIPTION - JOB_CHG_HOUR - JOB_LAST_UPDATE 2. **EMPLOYEE Table:** - **Primary Key:** - EMP_NUM - **Attributes:** - EMP_LNAME - EMP_FNAME - EMP_INITIAL - EMP_HIREDATE - JOB_CODE (foreign key referencing the JOB table) - EMP_YEARS 3. **ASSIGNMENT Table:** - **Primary Key:** - ASSIGN_NUM - **Attributes:** - ASSIGN_DATE - PROJ_NUM (foreign key referencing the PROJECT table) - EMP_NUM (foreign key referencing the EMPLOYEE table) - ASSIGN_JOB - ASSIGN_CHG_HR - ASSIGN_HOURS - ASSIGN_CHARGE 4. **PROJECT Table:** - **Primary Key:** - PROJ_NUM - **Attributes:** - PROJ_NAME - PROJ_VALUE - PROJ_BALANCE - EMP_NUM **Connections Explained:** - The JOB table connects to the EMPLOYEE table through the JOB_CODE attribute. - The ASSIGNMENT table connects to the PROJECT and EMPLOYEE tables through the PROJ_NUM and EMP_NUM attributes, respectively. These represent foreign keys derived from their respective tables. - These connections allow for queries across the database to gather information about job assignments, employee details, and related project data. This schema is useful for tracking employee assignments to different projects, maintaining job descriptions and charges per hour, and managing project values and balances.
