E-Book Overview A GUIDE TO SQL, Ninth Edition, provides an effective introduction to SQL programming using straightforward instruction, extensive hands-on exercises, and a strong foundation in real-world business applications. The Ninth Edition builds on the longstanding success of this proven text by presenting basic SQL commands in the context of a running case, in which a business uses SQL to manage orders, items, customers, and sales reps. A guide to sql pratt 9th edition pdf by Robert L. Pratt is a very important book for learning SQL programming language. This guide to sql pratt 9th edition pdf explains how the database systems implement SQL syntax for querying, managing transactions, and making changes to data.
This guide to sql pratt 9th edition pdf describes all the features of SQL implementations which are an essential part of database systems including database system access, query processing, transactions, concurrency control, recovery, security …. A Guide To SQL Pratt 9th Edition Pdf describes how these database systems implement SQL syntax for querying, managing transactions, and making changes to data. It also shows how the systems use SQL functions, regular expression syntax, and type conversion functions and formats. The best feature of this guide is its breadth of detail offered.
It provides a high-level view of database structures and provides useful details for taking strategies available in one implementation and possibly using it in another database engine. This allows you to take the naming you are familiar with, have been taught, or overheard and refer to it using that name and finding an appropriate redirection. All example SQL statements in this book execute against a set of tables, with data that you can quickly download. The A Guide To Sql Ninth Edition Pdf is a great converged reference for many common database implementation. If you find that you are working with many different databases or want a quick reference to see if a given structure is available in a given database implementation, this guide is for you.
Need a list of common data types for a category of data type: this guide has it. Explain that, when using the shorthand representation of a database, the primary key is underlined. Discuss the three Notes on pages 31 and Point out that a candidate key is a column or collection of columns on which all columns in the table are functionally dependent. The definition for a primary key really defines a candidate key as well. If two or more columns in a table are identified as candidate keys, choose one to be the primary key. The decision is usually based on the specific application for which the database will be used. Answer: primary key 2. Answer: candidate keys 3. Answer: underline Database Design 1. Point out that the determination of the database requirements is part of the process known as systems analysis. Design Method 1.
Review the design steps given in this section. To design a database for a set of requirements: 1 Read the requirements, identify the entities objects involved, and name the entities. Teaching Tip Use Figure as a visual aid as you explain each of the steps above and ask the students to identify the items listed in the steps. Database Design Requirements 1. Review the requirements that the database for TAL Distributors must support. The database must store specific data about sales reps, customers, items, orders, and order lines.
Teaching Use Figure to illustrate the requirements. Tip Database Design Process Example 1. Discuss the six steps to create a database design for TAL Distributors given a set of requirements. It is in this step that students often have trouble 2. Be sure to point out the functional dependencies discussed in step 4. Functional dependency is a difficult concept for some students to grasp. Review the embedded Questions and Answers on pages 38 and Normalization 1. Stress that database design is an iterative process. Once you create an initial database design, you must analyze it for potential problems.
Define Normalization. Normalization is a process in which you identify the existence of potential problems, such as data duplication and redundancy, and implement ways to correct these problems. The goal of normalization is to convert unnormalized relations into various types of normal forms. Define an unnormalized relation. An unnormalized relation is a relation table that contains a repeating group. A table in a particular normal form possesses a certain desirable collections of properties. Point out that normalization is a process in which a table that is in first normal form is better than a table that is not in first normal form, a table in second normal form is better than a table in first normal form, and so on.
The goal of normalization is to take an initial collection of tables and produce a new collection of tables that represents the same information but is free of problems. First Normal Form 1. Use Figures and to explain converting an unnormalized table to 1NF. In general, when converting a non-first normal form table to first normal form, the primary key usually will include the original primary key concatenated with the key to the repeating group. Teaching Tip Students have problems understanding a concatenated primary key. In a relational database, every row must be unique. There are instances when the only way to make each row unique is to consider more than one column as the primary key. Second Normal Form 1. Use Figure to illustrate a relation that is in first normal form but not in second normal form. Point out the redundancy; that is, duplication of data in Figure This duplication can cause update anomalies. Update anomalies occur when a column is dependent on only a portion of the primary key and fall into four categories: Instead of changing one row, it is necessary to update multiple rows.
Update Inconsistent If the same value appears in more than one row, for example, part description, an update could change one row without changing the other data rows. Cannot add a record correctly. Additions Cannot delete a record correctly. Deletions 4. Emphasize the fact that much real-world data including relational data are not well structured and have update anomalies. Define second normal form 2NF. Second normal form eliminates update anomalies caused by partial dependencies. A table relation is in second normal form 2NF if it is in first normal form and no nonkey column is dependent on only a portion of the primary key. A column is a nonkey column if it is not a part of the primary key. Point out again that you cannot determine functional dependence by looking at sample data.
Mention the Note on page If a relation has a single-column primary key , it automatically is in 2NF. Use Figure to explain converting to 2NF. Third Normal Form 1. Use Figure to illustrate update anomalies with a table in 2NF. Define determinant. Any column or collection of columns that determines another column is called a determinant. A candidate key is a column or collection of columns that could function as the primary key. Update anomalies also can occur when one nonkey column determines another nonkey column. Define third normal form 3NF. A table relation is in third normal form 3NF if it is in second normal form and the only determinants it contains are candidate keys. The definition used in this text for 3NF is really the definition for Boyce-Codd normal form BCNF. Use Figure to explain converting to 3NF. Show students how each progressive normal form solves update problems of the previous normal form.
Review the embedded Question and Answer on pages 50 and Teaching Tip Point out that normalization is a technique that allows us to analyze the design of a relational database to see whether it is bad.
A Guide To SQL 9th Edition Pdf Free Download unlike other SQL texts, which frequently abandon a running case for new materials, the authors break new ground toward the end of each chapter to review new commands and features of SQL. In Third Edition, rather than simply add new chapters on internationalization and XML support, 9th Edition authors spent the time to fully update their current SQL coverage to make sure that they stayed true to their original goals. SQL Structured Query Language is a domain-specific programming language that is used to interface with relational databases. It allows you to retrieve, update, or delete information from a database in a simple, structured manner. It is used primarily by business analysts, data scientists, and developers. SQL is flexible and powerful, and has been adopted by most major database management systems.
