MS Access is a Database Management System (DBMS) developed by Microsoft that combines:
- a relational database engine
- with a graphical user interface (GUI)
It is part of the Microsoft Office Suite and is used to:
- store data
- manage data
- retrieve data efficiently
The file extension of an MS Access database is:
👉 .accdb
Meaning:
- Represents a desktop database file
- Stores:
- tables
- queries
- forms
- reports
- other database objects
The main components of MS Access are:
- Tables → store data
- Queries → retrieve/filter data
- Forms → user interface for data entry
- Reports → formatted output
- Macros → automate tasks
- Data Macros → operate on table data
- Modules → advanced programming (VBA)
👉 All these components work together to manage and organize data efficiently
Procedure:
- Go to Create Tab
- Select Form or Form Wizard
- Choose Table/Query
- Select required Fields
- Set Layout Options
- Click Finish
👉 A form is created for easy data entry and viewing
Microsoft Access stores information as a database and treats anything that can have a name as an object. The main objects include:
- Basic object in MS Access
- Stores data in rows (records) and columns (fields)
- Example: StudentID, Name, Age, Class
- Used to retrieve and filter data
- Types: Select queries, Action queries
- Example: Students scoring above 90 marks
- User-friendly interface for data entry and editing
- Example: Student Entry Form
- Used for formatted output and printing
- Example: Sales Report
- Automate repetitive tasks
- Example: Auto opening a form
- Work directly on table data
- Advanced programming using VBA
👉 Together, these components help in efficient data management and automation
- Open MS Access
- Select Blank Desktop Database
- Enter database name
- Click Create
- Default table is created
- Add fields and rename them
- Example: ArtistID, ArtistName
- Save table with a name
- Enter data in Datasheet View
- Design structure in Design View
- Define Field Name, Data Type, Description
👉 Process: Open → Create → Name → Configure → Save → Enter Data
- Short Text → up to 255 characters
- Long Text → large text
- Number → numeric values
- Date/Time → date and time
- Currency → money values
- AutoNumber → auto-generated unique values
- Yes/No → Boolean values
- Attachment → files
- Hyperlink → URLs
- Calculated → computed values
- Uniquely identifies each record
- No duplicate or NULL values
- Example: StudentID
- Ensures uniqueness
- Prevents duplicates
- Supports relationships
- Creates index automatically
- Improve search and sorting speed
- Options: No, Yes (Duplicates OK), Yes (No Duplicates)
- Faster data retrieval
- Better organization
- Controls duplicates
👉 Data types control what data is stored, while keys and indexes control accuracy and performance
- Import from spreadsheets, text files, databases
- Option to link external data
- Export to Excel, Word, other databases
- Useful for sharing reports
- Supports ODBC (SQL Server, Oracle, DB2)
- Connects multiple systems
- Saves time
- Improves consistency
- Reduces duplication
- Supports real-world applications
👉 Access enables efficient data sharing and integration across platforms
