Mod J Web-2 SOLOMON DATABASE  The steps to creating a database are 1. Define entity classes and primary keys 2. Define relationships among the entity classes 3. Define fields for each relation (file) 4. Use a data definition language to create the database, which is the focus of this Module

Mod J Web-3 SOLOMON DATABASE  In Figure J.1 (p. 2) on the following 3 slides, we’ve recreated the correct database structure from Extended Learning Module C  Revisit Module C if you need a refresher

Mod J Web-4 SOLOMON DATABASE

Mod J Web-5 SOLOMON DATABASE

Mod J Web-6 SOLOMON DATABASE

Mod J Web-7 Creating Solomon’s Database  Data dictionary - contains the logical structure for the information  To create the Solomon Enterprise database: 1. Start Microsoft Access 2. Click on Blank Database in the upper left corner of the screen 3. Enter Solomon Enterprises.mdb as the database name 4. Click on Create

Mod J Web-8 Creating Solomon’s Database Click on Blank Database Enter a database name and click on Create

Mod J Web-9 Creating Solomon’s Database  Our recommendation: Create a relation (table) in Design view:  Must switch from Datasheet View to Design View  Click on View in the upper left corner and then Design View  Enter a table name  Use the Design View to enter the specifications for the table

Mod J Web-10 Creating Solomon’s Database To switch to Design View, click on View and then Design View This is Design View – our recommendation for creating the tables in a database

Mod J Web-11 Creating the Raw Material Relation  Enter the four fields of the Raw Material relation  Raw Material ID  Raw Material Name  QOH  Supplier ID  Click on the Raw Material ID row and then the key button to designate Raw Material ID as the primary key

Mod J Web-12 Creating the Raw Material Relation Primary key identifier and the Primary key button Integrity constraints for Raw Material ID

Mod J Web-13 Creating the Concrete Type Relation

Mod J Web-14 Creating the Bill of Material Relation  We created (in Extended Learning Module C) the Bill of Material relation to eliminate the many-to-many relationship between the Concrete Type and Raw Material relations

Mod J Web-15 Creating the Bill of Material Relation  The Bill of Material relation has a primary key composed of two fields (composite primary key):  Concrete Type  Raw Material ID  Composite primary key - consists of the primary key fields from the two intersecting relations

Mod J Web-16 Creating the Bill of Material Relation Composite primary key

Mod J Web-17 DEFINING RELATIONSHIPS WITHIN SOLOMON’S DATABASE  The final structural task is to define how all the relations relate to each other  That is, link primary and foreign keys  Foreign key - a primary key of one file (relation) that appears in another file (relation)

Mod J Web-18 Primary and Foreign Key Logical Ties

Mod J Web-19 Defining Relationships between Relations  To create relationships  Click on Database Tools in the menu area and then click on the Relationships button  Make each relation appear on the palette by highlighting each relation name and clicking on Add  Then click on the Close button

Mod J Web-20 Defining Relationships between Relations Relationship palette Select tables and click on Add

Mod J Web-21 Defining Relationships between Relations

Mod J Web-22 ENTERING INFORMATION INTO SOLOMON’S DATABASE  To enter information, you simply double- click on the appropriate relation name Supplier relation structure

Mod J Web-23 Entering Information

Mod J Web-24 Referential Integrity  Referential integrity ensures consistency. For example, that you don’t put a non-existent Supplier ID into the Raw Material relation  The relationships we set up for referential integrity guard against bad information  Integrity constraints – rules that help ensure the quality of the information

Mod J Web-25 Enforcing Referential Integrity

Mod J Web-26 Change the Structure of a Relation Click on View and then Design View and make the necessary changes

Mod J Web-27 CREATING A SIMPLE QUERY USING ONE RELATION  Query-by-example (QBE) tool - helps you graphically design the answer to a question  Suppose we wanted to see a list of raw materials that shows  Raw Material Name  Supplier ID

Mod J Web-28 Creating a Simple Query Using the Raw Material Relation First, click on Create and then Query Design Second, select the table, click on Add, and then close the box.

Mod J Web-29 Creating a Simple Query Using the Raw Material Relation The result of the query Drag and drop the appropriate field names and then click on the exclamation point (Run).

Mod J Web-30 Creating a Simple Query with a Condition Set the condition here

Mod J Web-31 CREATING AN ADVANCED QUERY USING MORE THAN ONE RELATION  Suppose we want a query that shows  All order numbers  Date of orders  Where the goods were delivered  The contact person  The truck involved in each delivery  The truck driver in each delivery

Mod J Web-32 Steps to Create an Advanced Query 1. Click on Create in the menu area and then Query Design 2. In the Show Table dialog box  Select and Add the relation names  Close the Show Table dialog box  Tables linked appear are joined by lines with  1 beside the table with the primary key  The infinity sign by the table with the foreign key

Mod J Web-33 Steps to Create an Advanced Query 3. Drag and drop the fields that you want from the appropriate relation into the QBE grid in the order that you want 4. Click on the exclamation point (Run) in the button bar to see the results of the query
