Microsoft Access Database Design

Microsoft Access is a relational database management system (RDBMS) that is part of the Microsoft Office suite.
It's commonly used for smaller-scale applications and projects due to its user-friendly interface and relatively easy-to-use features.
A key foundational concept in Access is a database, structured to hold and organize data.
Tables are the fundamental building blocks of a database in Access. Data is stored in rows (records) and columns (fields).
Data integrity is important in Access databases. It refers to the correctness and consistency of the data in the database.
Normalization is a crucial process in database design that aims to reduce data redundancy and improve data integrity. By properly normalizing a database, you reduce storage requirements, and it prevents errors during updates and modifications of data. Normalization involves breaking down tables into smaller tables linked together.
Relationships between tables are essential; they define how data in different tables are connected. Many-to-many relationships require intermediary tables to bridge the gap. Access uses primary keys and foreign keys to enforce relationships.
Primary Keys are unique identifiers for each record in a table. Foreign keys in related tables reference the primary key in the primary table.

Forms in Access

Forms are visual user interfaces that allow users to easily input, view, and update data in a database.
Forms can be customized with various controls for different data types, including text boxes, combo boxes, date pickers, and more.
Forms are designed for easy interaction with the database. They provide an input interface, making data entry simpler and reducing typos or errors compared to manually entering data in the tables directly.
Forms offer a formatted presentation of data.
Forms can be used to create reports, which display summarized data from the database in a visual format.

Reports in Access

Reports in Access are tools for extracting, organizing, and presenting data in a formatted way.
Reports are designed for summarizing data, highlighting trends, and presenting data visually.
Reports are not for data entry or editing data within a table.
Reports are often used for analysis or summary reporting.
They're particularly useful for producing graphical or tabulated data presentations extracted from database information.
You can format reports for presentation to users, including using charts, graphs, and other visual elements.
Data in reports is typically summarized, calculated, filtered from a database, and outputted in a structured format. They're distinct from forms and tables in their purpose of displaying data rather than its manipulation.
Queries are crucial components in report creation, pulling and filtering specific data to construct desired reports.
