...Fall 2013 - Homework 5 In SPUFI, for the Input dataset, specify a member in DB2.SQL with the naming convention HW5Qn, where n is the question number. Example, for question 1 it would be DB2.SQL(HW5Q1). Save the output for each question in a separate output file labeled by the question number. For example: OUTPUT.SQL .HW5Q1 File transfer each file to your PC and print the output files to turn in or cut and paste to a document if the text is all shown. You must include both the SQL and the output. LABEL the output by hand for each question. Remember, you must let SQL do the work, (don’t figure it out and hard code). Below is the ERD for this assignment: 1) Create the following tablespace with the naming conventions as specified: Tablespace RnnnTSSU in your database (RnnnDB) (the STUDENT table will go in here) using stogroup UNTDISK. (3 pts.) 2) Create the STUDENT table with the specifications from the ERD (Remember, bolded attributes are not null). DOB should have a datatype of DATE (not DATETIME.) (3 pts.) 3) Create an index on the primary key of STUDENT using the UNTDISK storage group (2 pts.) 4) Perform catalog queries to ensure your tablespace, table, and index were created (1 ½ pts.) 5) Insert the following data into the STUDENT table: ( 3 pts.)

...Spring 14 Spring 14 Homework #1 Polytechnic University of Puerto Rico Department of Computer Science, Electrical and Computer Engineering CECS 4202 Secc. 09 Prof. Alfredo Cruz Triana March 12, 2014 Polytechnic University of Puerto Rico Department of Computer Science, Electrical and Computer Engineering CECS 4202 Secc. 09 Prof. Alfredo Cruz Triana March 12, 2014 * What are the two major components of SQL and what functions do they serve? To answer this question we first have to understand what is SQL and how is it important for computer programming. Based on the information I found researching on this subject, SQL is nothing more than a database programming language designed for managing data held in a relational database management system also know as RDBMS. SQL also became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987. One of the major components of SQL is the data definition language or DDL, which manages table and index structure. This component is simply used for defining the database structure. DDL are the create, alter, rename, drop, and truncate statements which will be better explained in another question of this assignment. The other major component is data manipulation language or DML, which is used for retrieving and updating data. Said component is the subset of SQL also used to add and delete data with the use of insert, update...

...SQL Lab 2 Please Note: This lab requires that you understand how to write queries that were given in Lab 1 and also did hands-on work writing and running those queries. If not, you should please do Lab 1 (posted in Canvas with solutions) before working on Lab 2. Your next homework is based on these two labs. Chapters 7 and 8 in the Coronel/Rob textbook use the database for a hardware store called SaleCo. Please review the following SaleCo relational diagram –you’ll need to refer to it when writing SQL queries. NOTES: (1) The LINE table stores data about details of each transaction. Suppose an invoice is for three different products that the customer purchased, the LINE table associated with that invoice will contain three lines with each line number listing invoice number, line number, product code, quantity of the product purchased (under LINE_UNITS column), and price of the product (under LINE_PRICE column). (2) In the PRORDUCT table, the P_QOH column indicates quantity on hand (quantity in stock) for each product; P_MIN column lists the minimum quantity, i.e., when quantity on hand gets down to this level, the product needs to be re-ordered; the P_DISCOUNT column lists price discount for the product - for example .07 would indicate a 7% discount.

...Homework Assignment #4 Problems #65 - #94 from page 311. Please provide your answer after each problem and submit the file with your answers through Blackboard. EliteVideo is a startup company providing concierge DVD kiosk service in upscale neighborhoods. EliteVideo can own several copies (VIDEO) of each movie (MOVIE). For example, the store may have 10 copies of the movie “Twist in the Wind”. “Twist in the Wind” would be one MOVIE and each copy would be a VIDEO. A rental transaction (RENTAL) involves one or more videos being rented to a member (MEMBERSHIP). A video can be rented many times over its lifetime, therefore, there is a M:N relationship between RENTAL and VIDEO. DETAILRENTAL is the bridge table to resolve this relationship. The complete ERD is provided in Figure P7.65. Figure P7.65 EliteVideo ERD [pic] 65. Write the SQL code to create the table structures for the entities shown in Figure P7.65. The structures should contain the attributes specified in the ERD. Use data types that would be appropriate for the data that will need to be stored in each attribute.

...INTRODUCTION There is little doubt that no two people study the same way, and it is a near certainty that what works for one person may not work for another. However, there are some general techniques that seem to produce good results. So I decided to concentrate on working for this research because it’s very important for the readers to read this so that they have to step up in learning styles. My purpose of doing this research is to develop myself and to serve this thing as stepping stone to make a thesis and in consideration in making a book. Now I am making this just to show you how the proper process of learning is. The purpose of this research is to provide us significant ideas about real learning styles, study skills and thinking skills in analyzing some neither questions nor problems that we don’t know and to improve and enhance our memory in studying some lessons in a book. It also improves us to organize our studies, express our ideas clearly and effectively and how to communicate with others clearly and fluently. The first part of this research is focused on defining the three bodies of skills and you will know the utilization of effective language-learning strategy is. These three bodies of skills approaches us to have more experience on how to learn to be critical to success in school, considered essential for acquiring new good grades and useful for learning through out’s life. Of course this convinces us that these skills can be applied in other areas...
