Mastering Database Concepts - SchoolNotes
Teacher Note: Microsoft Access 2003 and 2007 were used to create the databases in this objective. All graphics in the guide are based on these versions. Make adjustments to notes and directions as necessary in accordance with the software version used in your classroom.
Database Uses in Business
I. Database Use and Purpose – A database is a tool used to organize, store, retrieve, and communicate groups of related information.
A. Examples of databases and database uses in business and society:
1. phone book
2. online library card catalog
3. payroll data including employee names, social security numbers, pay rates, exemptions, etc.
4. eBay and other online businesses use databases to maintain inventory and keep track of customers, products, vendors, pay pal accounts
B. Tables are the building blocks of all databases. They are used to group and organize the information within a database.
1. A table is an arrangement of columns and rows. It is the fundamental building block of all databases.
2. An entry is a single piece of data in a database table.
3. A field is a grouping or category of similar information contained in a table; a unique identifier for a category of information
4. A record is a complete description of all of the fields related to one item in a table.
II. Data Types, Field Properties, Primary Keys, and Printing
A. Before a database can be built, the user must first define its purpose and determine how the data will be organized into fields.
1. Fields should be formatted in accordance with the data they contain so that the database can be searched, used in calculations, and sorted as needed.
2. A field name should be short and descriptive
3. A data type defines the value of a cell and a field property defines the format of the data within the cell
B. Data types: used to control how data in a particular field will be searched, sorted, or used in calculations. The default format is text.
1. Text – used for data that will be sorted in alphabetical order or listed randomly, but will not be used in mathematical calculations.
2. Memo – a data type used for lengthy entries that allows combinations of text and numbers
3. Number – used for data that may be calculated, sorted, or filtered.
4. Date/time – data type used to arrange and sort data chronologically, often used with the input mask field property
5. Currency – data type used to format numbers as decimal values with a dollar sign. The default format for currency is two decimal places.
6. Auto Number – used to automatically assign a number to each record and to assist in preventing duplication of data.
7. Yes/No – a data type in toggle format that allows a user to select a yes or no value in a database cell. The default setting is No.
8. Lookup Wizard – a data type used to define preset values for database entries. This feature increases productivity and accuracy by reducing the amount of data entry required.
C. Field properties – used to control how data is entered in a field
1. Field size – used to control the size of the field, measured in characters
2. Format – used to control the layout of the field, such as one or two decimal places
3. Input Mask – a template-like field property that regulates how data is entered in a cell. For example, if the phone number input mask is used, the user will be prompted to input data in a specific format, such as (919) 555-5555.
4. Caption – a field property used for column naming that allows a more user-friendly and properly formatted field name than the field name stored in the database design
D. Editing and Printing – Procedures to add and delete records and fields, edit field names, rearrange fields in a database and print.
III. Database Management – The effectiveness of a database can be measured by the user’s ability to retrieve useful information.
• An effective database is one that contains timely information and thus requires continuous maintenance.
o Consider the telephone directory and the amount of information that must be gathered, edited, and processed to provide customers with accurate information.
• Many tools are available to assist in the retrieval, processing, and manipulation of database information.
A. Filters allow for the retrieval of information that meets specific criteria.
1. Filter by Selection – filters for information related to an active cell
2. Filter/Advanced Filter Sort – used to define specific search criteria
B. Sorts allow for information to be arranged in a specific order such as alphabetical, chronological, ascending, or descending.
C. Database Relationship – a link between two or more tables in a database
• The relationship is developed when common fields in the tables are linked, such as the Customer ID field in a Customer Address table and the Customer ID field in a Purchases table.
• The relationship enhances the power of the database by allowing retrieval of data from multiple tables and eliminating the need for data duplication.
1. Types of Relationships
a. One-to-Many is a type of relationship that occurs when a record in one table is linked to more than one record in another table.
b. Many-to-Many relationships are formed by connecting two or more tables that have a one-to-many relationship. The connection is made by a Junction Table.
2. Relationship Components
a. Primary Key – used to format each record in a database as a unique entity. Primary keys allow database tables to communicate.
i. May be assigned to an existing field that contains information unique to each record.
ii. May be assigned via an AutoNumber field that automatically assigns a unique number to each record.
iii. The linked fields must be of the same data type and size
b. Foreign key – when tables are linked by the primary key, the related field in the second table is known as the foreign key
c. Junction table – a table used to join primary key fields from multiple tables
d. Join line – a graphical representation of the link between two or more tables
e. Referential integrity protects related data that is stored in multiple tables.
Referential integrity would prevent a customer in a customers table from being deleted if the customer’s ID also appears in the order table
IV. Raw Data Import - A useful and practical method for obtaining information from other sources and creating database tables. Eliminates the need for repetitive data entry and assists in the protection of the data’s integrity.
A. Must be formatted as text
B. Must be separated at field and record breaks with a separator, such as a comma (delimitated)

Independent Practice: Filtering and Sorting a Database
YOU WILL COMPLETE THIS ACTIVITY INDEPENDENTLY TO APPLY WHAT YOU HAVE LEARNED ABOUT SORTING AND FILTERING A DATABASE. FOR EACH ITEM, YOU MUST COPY THE RESULTS OF THE AFFECTED FIELD(S) INTO A WORD DOCUMENT. YOU SHOULD END UP WITH 9 TABLES IN ONE WORD DOCUMENT. LABEL EACH TABLE APPROPRIATELY AND PROVIDE AN EXPLANATION OF HOW THE SORT/FILTER WAS PERFORMED FOR EACH.
Note: Be careful not to click a yes/no box by accident and change its value
Part I: Open the B&B database and complete the following sort tasks in the HistoricInns table.
1. Simple sort: Sort by the B&B Name in ascending order. Copy/paste the sorted B&B field to a word processing document.
2. Simple sort: Sort by the Number of Rooms field in descending order. Copy/paste the Inn field and Rooms field to a word processing document.
3. Complex sort: Move two appropriate fields adjacent to each other to accomplish the sort. Primary field: Rooms in ascending order; Secondary Field: Inn in ascending order.
If using Access, the left-most field will be sorted first, so for this sort, you must drag the Rooms field in front of the Inn field. Copy/paste the two fields to a word document.
Part II: Using the same database, complete the following filter by selection tasks
4. Historic Inns which do not allow pets
5. Historic Inns which allow pets
6. Historic Inns which allow children under the age of 10
7. Historic Inns located in town
(continued on the next page)
Part III: Using the same database, complete the following advanced selections
8. Apply an advanced filter that selects records according to the following conditions:
• Historic Inns that have more than 4 rooms available
• Descending order
• Allow both children and pets.
Write a criterion statement using operators
9. Apply an advanced filter that selects records according to the following conditions:
• Historic Inns that have less than 6 rooms available
• Ascending order
• Located in a small town/country place
• Allows children.
Write a criterion statement using operators
10. Save and submit your work according to teacher directions.
