  Database Basics In this section, you’ll learn how to:

  • Create a new database
  • Create tables
  • Create records
  • Create forms
  • Create queries
  • Create reports

  

Create a new database

Start OpenOffice.org Base.

1. Your screen should look like this:

  In the Database Wizard window, click Create a new database.

2. Then click the button.

  When the Save as window appears, create a new folder in the 3.

  My Documents folder called Practice Base Files.

  Tip: To create a new folder, make sure the My Documents folder appears as the Save In folder.

  Then click the icon. Double-click the Practice Base Files folder.

4. It should appear as the Save In folder.

  In the File name box, type: 5.

  Family.odb

  Tip: Base will automatically add a file extension for you when you leave the Automatic file name extension box checked. Click the button.

6. The window for the Family database should open:

  Identify database elements

  Elements of databases A database stores information in an organized way, and makes it easy to get information in and out.

  Tables store data within the database. Forms make it easy to put data into tables. Queries pull out specific data. Reports put data in an easily-read format.

  Form Query Table

  Table Report

  1. In the Database list, click Tables.

2. Click Queries.

3. Click Forms.

4. Click Reports.

11. The key field

  When the alert window popped up, and you clicked the button, Base added the ID field to the table.

  The ID field is now the table’s primary key, or key field. That means it can’t contain any duplicates.

  Every table should have a key field. For example, if a hospital keeps a database, each patient can have a unique ID number in the key field.

  That way, if it has more than one patient named John Baker, it can easily distinguish John Baker, ID #326 in for a checkup, from John Baker, ID #298 who needs his gall bladder removed.

  Create records Double-click the table My Family in the Tables list.

  FlowerStore

  When to filter Filtering records works like a query, bringing up specific information from a table.

  But unlike a query, your filtering doesn’t remain part of the database. When you perform a query and save it, the query remains with the database, even after you close it. Filtering does not.

  Since you can’t save filtering like a query, filter records when you need quick results. Think of filtering as a temporary, quick, “on the spot” query.

  Create table relationships

  What are “relationships?” Relationships are links that associate a field in one table with a field in another.

  An example is a school database with two tables:

  • Students • Classes The Students table holds students’ names and addresses:

  Students Student Name Address John Elm St.

  Jane Oak St.

  The Math Class table holds information about the students in math class:

  Math Class Student Name Grade

  John A Jane B

  Both tables have a Student Name field. By linking the Student Name fields, you make sure that John in the Students table is the same John listed in the Math Class table:

  Students Math Class Student Name Address Student Name Grade

  John John Jane Jane Examine current table relationships On the Menu Bar, click Tools, then Relationships.

  1. When the Add Tables window appears, double-click 2.

  Customers .

  The Customers table should appear in the Relationships work area: In the Add Tables window, double-click Employees.

3. The Employees table should appear in the Relationships work

  area:

  4. Double-click Order Details.

  5. Double-click Orders.

  6. Double-click Products.

  7. In the Add Tables window, click the button.

  The relationships window should now look like this: Add relationships

  Place the cursor on the Title Bar at the top of the Employees 1. table.

  Click and drag the Employees table to place it under the 2.

  Customers table.

  Click and drag the Orders table to place it between the 3.

  Customers table and Order Details table.

  Click the Order ID field in the Order Details table, then drag it 4. and rest it on top of the Order ID field in the Orders table.

  The Orders table should look like this: Release the mouse button.

  5. The relationships window should now look like this:

  The Order ID field in the Orders table is linked to the Order ID field in the Order Details table.

  The same Order ID number in both tables refers to the same order.

  On the Menu Bar, click File, then Close to return to the 6.

  FlowerStore database window.

  When the alert window appears, click the button.

  7. On the Menu Bar, click File, then Exit.

  8.

11. Exit Base.

  

Working with Queries

In this section, you’ll learn how to:

  • Create queries
  • Sort results
  • Add criteria
  • Employ Boolean operators

  Create queries 1.

  Start Base, and open the FlowerStore database.

  2. In the Database list, click Queries.

  3. Click Create Query in Design View.

  The Query Design window should appear: In the Add Tables window, click Customers.

4. Then click the button.

  Click the button.

  5.

  This adds the Customers table to the query. The query window should look like this: Add fields to query 1.

  Click the arrow in the first column’s Field box.

2. When the list appears, click Customers.Customer ID.

  The query design grid should look like this: Drag the First Name field from the Customers table to the 3. second column of the query design grid.

  Release the mouse button. The First Name field should appear in the design grid: Drag the Last Name field to the design grid.

4. The design grid should look like this:

  The query is now set up to show the Customer ID, First Name, and Last Name of each customer in the Customers table. Run the query On the Toolbar, click the icon.

1. The query window should now look like this:

  The query shows the Customer ID, First Name, and Last Name of each customer in the Customers table:

  Sort results In the Last Name field, click in the Sort row.

1. When the drop-down arrow appears, click it, then click Ascending .

  It should look like this: On the Toolbar, click the icon.

2. The query should run, and sort the records alphabetically by

  Last Name :

  In the Last Name field, click in the Sort row, then click (not 3.

  sorted).

  It should look like this:

  Add criteria 1.

  In the query’s Customer table, scroll down to the State field.

  2. Add the State field to the query design grid.

  3. In the State field, click in the Criterion row.

  Type: 4.

  VA Press the ENTER key.

5. It should look like this:

  Tip: Notice that Base automatically surrounded the VA criterion with quotes. That’s because the State field stores text data. In database query language, quotes signify a string of text. If the field stored number data, Base wouldn’t have added anything.

  On the Toolbar, click the icon.

6. The query results should look like this: It has returned all customers who live in the State of VA.

  Employ Boolean operators

  What are Boolean operators? Boolean operators are expressions such as AND, OR, NEITHER, and NOR that allow you to add multiple criteria to a query. They take their name from George Boole, the mathematician who first used them.

  If you had a T-shirt store with an Base database, for instance, and you wanted to find out how many of your California customers had ordered blue T-shirts, you’d employ the AND operator in your query: customers from California

  AND

  who also bought blue T-shirts If you wanted to see how many customers were from California (these California customers could have bought T-shirts of any color), and how many customers bought blue T-shirts (these blue T-shirt customers could be from anywhere), you’d employ the OR operator: customers from California

  OR

  customers who bought blue T-shirts

  Employ the OR operator In the State field, click in the Or row under the criterion VA.

1. Type: 2.

  MD then press the ENTER key.

  The design grid should look like this: Tip: The two common Boolean operators are AND and OR. They’re easily confused. If you don’t know which to use, ask yourself the purpose of the query: Do I want to find customers with a state of both Virginia AND Maryland? No—a customer can’t be in two places at once.

  Do I want to find customers with a state of either Florida OR Maryland? That makes sense, so this query would use the OR operator.

  Click the icon.

3. The query results should look like this:

  Employ the AND operator 1.

  Remove the query criteria from the State field. Tip: Highlight them, then press the DELETE key. The design grid should be blank: 2.
