2
Mod J-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
3
Mod J-3 SOLOMON DATABASE In Figure J.1 (p. 474) 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-4 SOLOMON DATABASE

Mod J-5 SOLOMON DATABASE
6
Mod J-6 SOLOMON DATABASE
7
Mod J-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.accdb as the database name 4. Click on Create
8
Mod J-8 Creating Solomon’s Database 1. Create a new database by clicking on Blank Database 2. Enter SolomonEnterprises.accdb
9
Mod J-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
10
Mod J-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
11
Mod J-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
12
Mod J-12 Creating the Raw Material Relation Primary key identifier and the Primary key button Integrity constraints for Raw Material ID
13
Mod J-13 Creating the Concrete Type Relation The fields for Concrete Type Primary Key Integrity Constraints
14
Mod J-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
15
Mod J-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
16
Mod J-16 Creating the Bill of Material Relation Composite primary key
17
Mod J-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)
18
Mod J-18 Primary and Foreign Key Logical Ties
19
Mod J-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
20
Mod J-20 Defining Relationships between Relations Relationship palette Select tables and click on Add
21
Mod J-21 Defining Relationships between Relations
22
Mod J-22 ENTERING INFORMATION INTO SOLOMON’S DATABASE Double-click on any table to begin entering information
23
Mod J-23 Entering Information We double-clicked on the Supplier table and can now begin entering information We have completed entering all supplier information
24
Mod J-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
25
Mod J-25 Enforcing Referential Integrity Because we entered a non- existent Supplier ID (445) that doesn’t exist, Access will not allow us to continue If you try to close the window, Access will allow you to change the information or save the good information without the bad
26
Mod J-26 Change the Structure of a Relation You can change the structure of a relation by clicking on View and then Design View In Design View, you can change the structure of a table
27
Mod J-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
28
Mod J-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.
29
Mod J-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).
30
Mod J-30 Creating a Simple Query with a Condition Set the condition here
31
Mod J-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
32
Mod J-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
33
Mod J-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
34
Mod J-34 Steps to Create an Advanced Query From the Show Table box, select the appropriate tables – Customer, Order, Employee and Truck
35
Mod J-35 Steps to Create an Advanced Query Drag and drop the appropriate fields
36
Mod J-36 Steps to Create an Advanced Query The completed query

49
Mod J-49 Grouping and Sorting Information Top-level grouping: Allows you to choose ordering. Since we created a query, Access has defaulted to the first field Further grouping: Lets you specify groups within the top grouping of Concrete Type, but we don’t want any further grouping Sorting: Next we have a chance to sort our information
