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. Define attribute. An attribute is a characteristic or property of an entity. The terms column and field are used as synonyms in many database systems. Define relationship and one-to-many relationship. A relationship is an association between entities. There is a one-to-many relationship between sales reps and customers in the TAL Distributors database.

One sales rep represents many customers, but each customer is associated with only one sales rep. In a relational database, each entity has its own tables, and the attributes of the entity are columns in the table. A one-to-many relationship is handled by using common columns in the two tables. Use Figure to illustrate the one-to-many relationship between sales reps and customers. Use Figure to illustrate repeating groups multiple entries in an individual location in a table. Define relation. A relation is a two-dimensional table with specific properties. These properties include:  Entries in the table are single-valued. Use Figure to discuss the six properties of a relation. See the Note on page Mention that the formal term for a table is relation, and the formal term for a row is tuple.

A row also is called a record. Columns in a table are also called fields or attributes. DBDL Database Definition Language is a commonly accepted shorthand notation for showing the structure of a table. After the name of the table, all of the columns in the table are listed within a set of parentheses. While each column in a table has a distinct name, the same column name can be used in more than one table within the same database. When two or more tables in a database use the same column name, qualify the column name; that is, combine the table name and the column name Teaching Tip Reinforce the material in this section by using either the Colonial Adventure Tours database or the Solmaris Condominium Group database and asking students to identify the entities, attributes, and relationships. Quick Quiz 1 1. Answer: entity 2. Answer: attribute 3. Answer: relationship © Cengage Learning. Functional dependence is a formal name for what is basically a simple idea.

In a relational database, column B is functionally dependent on another column A or possibly a collection of columns if a value for A determines a single value for B at any one time. Another way of defining functional dependence is to say that A functionally determines B. Use Figure to explain functional dependence. Make sure that students understand what functional dependence is before proceeding or they will be lost for the remainder of the chapter. Review the embedded Questions and Answers on pages 28 and Use Figures and to point out that you cannot determine functional dependencies by looking at sample data. Primary Keys 1. To make each row distinct, one or more columns must uniquely identify a given row in a table. This column or collection of columns is called the primary key. A more precise definition for a primary key is the following: Column attribute A or a collection of columns is the primary key for a table relation , R, if: Property 1: All columns in R are functionally dependent on A.

Property 2: No subcollection of the columns in A assuming that A is a collection of columns and not just a single column also has Property 1. Review the embedded Questions and Answers on pages 30 and 31 to make sure that students understand the concept of a primary key. 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.

These properties include:  Entries in the table are single-valued. Edgar Codd developed the process and gave it the name normalization. A row can only exist in the ORDERS table if the customer number matches a row in the CUSTOMER table and the rep number matches a row in the REP table.
