StayWell also rents out properties on a weekly basis to students attending summer school in the Seattle area. Design a database to meet the following requirements, using the shorthand representation and a diagram of your choice. For each student renter, list his or her number, first name, middle initial, last name, address, city, state, postal code, telephone number, and e-mail address. For each property, list the office number, property address, city, state, postal code, square footage, number of bedrooms, number of floors, maximum number of persons that can sleep in the unit, and the base weekly rate. For each rental agreement, list the renter number, first name, middle initial, last name, address, city, state, postal code, telephone number, start date of the rental, end date of the rental, and the weekly rental amount. The rental period is one or more weeks.
In anticipation of a change to the database, you are asked to provide a list of all products that have 'Man-Made' or 'Man Made' in the the composition text. (HInt: It is easiest to use LIKE in this instance.) In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060. Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'. (HINT: This problem is a little tricky because you need to replace both 'Man-Made' and 'Man Made'. The way to do this is to use a replace within a replace.)
If you sell a house more than once, it is treated as different "property" for each sale. Draw an entity-relationship diagram and write a database design outline. Q2. Law Office: You are trying to automate the records for your uncle's law firm. Multiple attorneys work for the firm, and for each of them you want to store their first name, last name, date hired, hourly billing rate, and date promoted to partner (blank if the attorney is not a partner). Each attorney has multiple cases, which is identified by a unique "docket number". Each case has a name and description, is worked on by only one attorney, and involves a single client. For each client, you want to store a first name, last name, middle name, phone number, address, city, state, and zip code (assume you do not have a zip-code table). Finally, you want to keep track of the billable hours spent on each case. For a single case, this comprises information that looks like Hours Billed Date 2/24/2005 Description Prepare brief…
PLz help with the following: Translate your ER diagram into a relational schema in the form of SQL DDLs. Choose appropriate data types for each attribute and include primary key and foreign key constraints, Check and Not Null constraints.
In the Testa EV database design described in the previous question, please complete a field specifications form for the field 'Model_Cost' of the table 'Model_T'. The field records the cost of producing a specific EV model. Because its data come from the cost data of specific parts used to build the model, its value can be entered later and editing is allowed (null is allowed). The field value is required. Only decimal numeric data are supported for the entered value. The field can store a maximum of 10 digits (including 2 decimal places). The user of the database (data analyst) is responsible for entering and maintaining the data. No specific range of values is specified for this field. You should enter 'N/A' (or leave it unchecked) for elements that are not applicable.
This question is related to the Database:- Suppose you are creating a database for a library management system. Explain how you would make a table for the "books" entity and insert some sample data, and then alter the table to add a new column for the "authorID" attribute and update "authorID" with some data. Finally, make a SQL query to retrieve all the books that were published after the year 2000. Note that this book schema has several columns, including "book_id" as the primary key, "title", "authorN", "publisher", "publication_year", "isbn", "language", and "num_pages". It also includes "available" column that is set to "true" by default and can be used to track the availability of the book. Please don't use handwriting...

Answer questions 2.1 to 2.4 based on the following schema. Note that primary keys are in BOLD. Note also that attributes with the same name in different tables are foreign keys. For example, doctorID in the Treatment table is a foreign key that refers to the Doctor table. Doctor(doctorId:integer, specialtyID:integer, firstName:varchar(20), lastName:varchar(20), salary:numeric(11,2)) Specialty(specialtyID:integer, specialtyName:varchar(20), specialtyCost:numeric(11,2)) Treatment(doctorId:integer, patientSSN:integer, dateTreated:date, costOfTreatment:numeric(11,2)) Patient(patientSSN:integer, firstName:varchar(20), lastName:varchar(20), street:varchar(30), city:varchar(15), state:char(2),zipCode:integer(5)) 2.3) Write an SQL statement to increase the cost of all Specialty treatment by 2.5% 2.4) Write a SQL statement to delete all treatment rows that were done before 2015 and cost less than $500. 2.5) Write an SQL statement to select all Specialties where the specialtytName has a null…
