Construct an (E)ER diagram for a hospital system with the following requirements: Patients are described using unique ss# as well as name, insurance, admitted date, and checked-out date Doctors are described using unique dss# as well as their names and specialization. Each patient may have a set of tests, described by test id, test name, date, time, and results. These tests are performed by doctors. Then convert the (E)ER diagram to a collection of relation tables (Relational database schema). Determine all the primary and foreign keys.

Requirement Analysis

A process that determines the user expectations for a software product is called requirement analysis. In software engineering, requirement analysis is known as requirement engineering. It involves communication with end-users and stakeholders to determine whether the system or software requirements are validated, conflicts are solved, and key requirements are documented. The first activity of the Software Development Life Cycle (SDLC) is requirement analysis.

Problem: design a er diagram for a database to keep track of building inspections required by a department of Damaged Buildings (DB). DB building inspections are requested by builders every month. Each building inspection is either passed or not. Inspections have a type code (3 characters, e.g. PLU, FRM, ELE, etc.) and possibly sequencing requirements. Some inspections cannot be performed before other inspections, e.g. final plumbing inspection cannot be performed until the framing inspection is passed. Each inspection has a numeric score, with 75 or more out of 100 being sufficient for a pass status. Each inspection data contains the date of inspection, inspector identification, inspection score, and textual information about the inspection. The textual information can be updated later, but the score can never be changed. FODB maintains a pool of inspectors. Each inspector has a unique 5 digit employee ID, name, and date they were hired. They can conduct any type of inspection but…

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality.

Please draw an EER diagram for the bank DB system. It requires to design & plan & document a bank system. Your EER model must include supertype and subtypes inheritance associations based on your initial ER model. Relationship constraints and completeness rules (discussed in the EER module) must be included. Requirements: Metadata: define what attributes (data) represent an object (i.e. account type) and data properties (data types, valid range of values, required vs. optional, etc.) Entities (objects): Account owner, dependent (joint family), Checking account, Savings account, Money Market account, loan account, or other banking objects, online account, etc. (suggestion: Define at least 10 entities) Relationships: customer deposit or withdraw money with account, and more. Identify the possible entity sets and their attributes, the relationships among the attributes.
Suppose you are given a relation grade_points(grade, points) that provides a conversion from letter grades in the takes relation to numeric scores; for example, an “A” grade could be specified to correspond to 4 points, an “A−” to 3.7 points, a “B+” to 3.3 points, a “B” to 3 points, and so on. The grade points earned by a student for a course offering (section) is defined as the number of credits for the course multiplied by the numeric points for the grade that the student received.Given the preceding relation, and our university schema, write each of thefollowing queries in SQL. You may assume for simplicity that no takes tuple has the null value for grade. Find the ID and the grade-point average of each student.
