Study Notes

Microsoft Access Database Creation and Management

Microsoft Access is a relational database management system, along with SQL Server, Oracle, and DB2.
A relational database is a collection of tables that are related to each other based on a common field.

Creating a New Database

To create a new database, click on the "Create a new database" button and enter a name, typically in the format of "Last Name + First Initial of First Name".
When saving a database, Access saves the design of the Access objects, not the database itself.

Characteristics of Relational Database

Each record in a table must be uniquely identified using a primary key.
Tables are related to each other based on a common field using foreign keys.
Primary key (PK) uniquely identifies each record in a table, while foreign key (FK) connects one table to another.

Relating Tables using PK and FK

The primary key in one table is the common field that relates to another table.
The foreign key in the second table connects to the primary key in the first table.

Querying a Database

Using the "Between" operator to retrieve records within a specific range, e.g. "Product Code between CS and DS".
Using the "Greater than" operator to retrieve records that exceed a certain value, e.g. "Invoice Amount > 20,000".
Using the "And" and "Or" operators to combine conditions in a query.
Using the "OR" operator to retrieve records that meet either of two conditions, e.g. "First Contact date < 01/01/2018 or Invoice Amount > 20,000".

Access Data Types and Field Properties

Access data types include Text, Date/Time, Currency, and Yes/No.
Field properties include Field Size, Required, and Default Value.

Creating and Modifying Tables

Creating a table involves defining the fields and their data types.
Modifying a table involves adding, deleting, or rearranging fields.
Data can be entered sequentially in Datasheet view.

Data Integrity and Primary Key Rule

No "null" value can be allowed in a primary key.
No two records can have the same primary key.
A primary key can be a composite key, consisting of more than one field.

Importing External Access Tables and Excel Worksheets

Importing tables from another Access database or Excel worksheets.
Reviewing the Excel file before importing it into Access.

Forms in Access

Forms are used to customize the data entry screen.
Forms are created for the convenience of the user and to update data tables.
Forms can be used to restrict user access to certain data.
Forms can be created using the "Form Wizard" and customized in Design View.

Creating and Modifying a Form

Creating a form involves selecting the table and fields to include, and choosing a layout and style.
Modifying a form involves rearranging fields and adjusting their properties in Design View.
