Database ConceptsTerms

Database: collection of objects that allow you to store data, organize it and retrieve it in any way you want. It may contain:Tables: structure that allow you to organize the data

so that it's easy to find laterForms: let you input the data into the tables Reports: print selected information from the tables

Relational Database: stores data in various interrelated tables where data is stored, accessed and presented without affecting the structure

Design a Database


Relational Database Designing ProcessSequential process for developing a

database planThis process consists of seven steps

Database purposeReview existing dataCreate list of fieldsOrganize fields into tablesEnter sample data and verify if changes are

requiredDesignate primary and foreign keysDetermine table relationships


Define Database PurposeStatement of purpose

Defines the scope of a databaseHelps guide the designImplies the kind of dataDetermine the probable users


Review Existing Data


Relevant data to the statement of purposeCan be in paper or electronic

PaperInternal Business FormsGovernment FormsInvoices

ElectronicSpreadsheetsWord documentsDatabases (Access, MS SQL, Oracle, etc.)Web pages

Determine Fields


The required fields depend on the information required by the userReportsSummary information

Group Fields Into Tables


Business RulesPolicies and procedures that govern

operation of an organizationDefine methods for data entry in a databaseDefine a standard naming convention for

objects. Example: Student name object can be S_Fname and the lastname can be S_Lname

Database DesignClass Exercise

You are required to develop a database to keep track of the books being lent by the university library.

AssumptionsOnly students are allowed to take booksThe books can only be lent for two weeksNo other service will be tracked through this

database


Database DesignClass Exercise

Develop a list of data required for this databaseHow many tables are required? Why?What information is required for each table?


Normalize Data


NormalizationProcess organizing data in a databaseOptimizes table structureRefining database by reducing complex data

into simple table structuresOptimizes by

Eliminate redundancyEliminate inconsistency dependency between

tables

Normalize Data


Break data into smallest values possibleAssure data is not repeatedBreak repeated data into separate tablesAvoid empty fields as much as possibleConsistent references in tables (naming

convention)

De-normalization


DefinitionCombining tables into a bigger table

UsesMake queries run fasterKeep similar data togetherKeep table structure simple

Designate Primary and Foreign Keys


Primary KeyField with unique valuesValues identify each recordUsed to create relationships between tablesCan be of any data type except memo, OLE

or AttachmentCan never be blankValues do not change or have duplicates

Designate Primary and Foreign Keys


Composite KeyMade of the union of two unique fields

Foreign KeyField that relates to primary key of another

tablePrimary key acts as record indexHelps implement relationship between

tablesForeign key helps establish relationship

with primary key

Designate Primary and Foreign KeysClass Exercise

Define a primary and foreign key for each table. This field identifies each individual in a unique way.

List any field that contains a limited list of items. Example: City or state.

Define default values when possible. Example: 90% of students will be from PR.


Determine Table Relationships


Representation of association among data contained within tables

Helps poll matching fieldsOne-to-one relationship

Primary key and foreign key are uniqueOne-to-many relationship

Primary key unique with many foreign key values

Building a Database


Create a Database


To create a databaseOpen Access 2007In the Getting

Started screen select blank database

Write database name and select location.

Press Create

Create a Table


Access creates a new table when a new blank database is created

New tables can be created by selecting the table icon on the Create tab

Table Views


Tables can be viewed in several ways. The two most common views are: Datasheet: This is the

default view and presents record values

Design: This presents the table and field properties but does no present record values

Field Insertion Feature


Allows adding new fields from datasheet viewWrite the field name in

the column headerRepeat for each field

Data Types


Text: Contains characters up to 255Memo: Advanced text field. Can hold up to 2 GB of

data with rich text formattingNumbers: Numeric values up to 16 bytesDate/Time: Stores and manipulates date and time

valuesCurrency: Monetary valuesAutoNumber: Automatically creates a numeric

value with new records. Are usually used as primary keys.

Yes/No: Boolean information (true or false)Hyperlink: Stores web addressesAttachment: Add files to a recordMultivalued: Can have more than one value

New Fields


Fields can be added through:Field insertion

feature Design view

Multivalued fields are added through the Lookup Wizard

Creating Tables


Create the tables for the books circulation class exercise

Use the datasheet view as well as the design view

Table Maintenance


Tables can be:DeletedRenamedExportedAdd a description in the Table Properties

Dialog

Table Properties


Allows for a detailed description of the table

Presents information about the tableCreate dateModified date

Allows to hide a tableAllows for row

tracking when used by multiple simultaneous users

Referential Integrity


Process to ensure data validity across two tables

It is enforced by ensuring values in a foreign field have corresponding values in the primary key

Referential integrity prevents the entering of invalid data

Benefits of Referential IntegrityAvoid data lossAvoid updating data

Referential Integrity


Referential integrity between two table can be set if:Both tables are in the same databaseThe matching field is a primary key in one

table or has a unique indexThe related fields have the same data type

Table Relationships


In the Database Tools tab select relationships

If no relationship exists, Access brings the Show Tables or Queries dialog to add them to the relationship

Once added, drag the primary key to the foreign key.

This brings the Edit relationships dialog

Referential integrity can be enforced here

A line is drawn between tables to indicate relationship

Table Relationships


Create the table relationships for the books circulation class exercise

Enforce referential integrity as required

Save a Database in a Previous Version


In the Office Button menu select Save As

Managing Data in a Table


Modifying Data


Users can:Search for recordsReplace Data in recordsAdd recordsDelete RecordsModify Records

Find Command


Helps locate specific data.Has various find options

Replace Command


Helps replace specific data with new data

Has various replace options

Totals Features


Provides simple math functions to the tables

Sorting Records


Can sort dataAscending Descending

The order is based on Numeric

informationAlphanumeric

information

Subdatasheets


Datasheet nested within another datasheet

Contains data related to the first datasheet

Subdatasheet presence is indicated by + sign on the row


Managing Data


Class ExerciseFill the created tables with at least 10

records eachDelete at least 1 record from each tableModify at least 1 record from each table

Queriyng a Database


Querying a Database


Looking for data in a database is difficult unless there is mechanism for extracting and isolating is

A database is effective when data can be retrieved as easily as it was entered

Queries greatly reduce the data retrieval time

Filter Feature


Display only the records that match your criteria

Filter data based on the values in a column

Filter by:Text for the text data

typeNumber filters for the

number data typeDate filters for the date

data typeMultiple filters can be

applied to a table at the same time.

Query Wizard


Select Query WizardSelect type of querySelect query fieldsRequest query detailAdd title. Click FinishQuery result shown

Query Types


Simple: Can select fields from multiple tables and queries

Crosstab: Can perform simple calculationsFind duplicates: Can find duplicate field

valuesFind unmatched: Finds records in a table

with no related records on another table

Class ExerciseCreate a query of studentsCreate a query of books

Query Criteria


Search condition to retrieve specific informationThese are used to compare criteria value with

values in the columnCalculations can also be performed

Comparison Operators


Symbols used to compare two valuesWhen set in criterion establishes results

after comparisonThe result is always a true or false

List of Comparison Operators


= : Equals< : Less than<= : Less than or equal to> : Greater than>= : Greater than or equal to<> : Not equal toBetween And : Within a rangeIs Null : Null values

Conditional Operators


Test for the truth of a comparisonThe result is always a true or falseParenthesis can be used to change the

order of evaluation

List of Conditional Operators


AND : True if both conditions are trueExample: >2 AND <>10

OR : True if either condition is trueExample: <10 OR >100

NOT : True if the single instance is not trueExample: Not Between 2 and 10

Create a Query
