Database

An organized collection of data designed to be easily accessed, managed, and analyzed. It provides a structure to store information efficiently.

Flat file database

A simplified database with data in rows and columns, often with no complex relationships between data. Example: A spreadsheet.

Relational database

A database with data stored in multiple tables that link together using shared fields and keys. It allows for complex relationships between data.

Tables

The building blocks within a database that store data arranged in rows (records) and columns (fields).

Study Notes

Database Concepts

  • A database is a structured collection of data. It helps organize, manage, access, and analyze large amounts of information efficiently.
  • Databases are used for various purposes, from managing personal address books to complex business records.
  • Databases are categorized into flat-file and relational databases.
  • A relational database stores data in interconnected tables, linked by common fields.
  • Microsoft Access is a popular relational database management system (RDBMS).

Advantages of DBMS

  • Efficient and reliable data retrieval methods.
  • Reduction of data redundancy (duplication).
  • Increased efficiency, speed, and flexibility in accessing and searching information.
  • Sharing of data among multiple users based on individual needs.
  • Data integrity, ensuring that data conforms to organizational standards.

Database Components/ Structure

  • Fields: Columns in a table, describing a particular attribute of all records.
    • Example: Roll No, F_Name, Marks
  • Records: Rows in a table, holding the values for all fields related to a person or entity.
    • Example: A row with a student's roll number, name, and marks.
  • Data: Set of valid characters representing information for a field, such as name values, numbers, and text.
  • Tables: The fundamental building blocks of a database.
  • Forms: User-friendly interfaces for entering data into tables.
  • Queries: Used to extract specific data or perform operations on the database.
  • Reports: Used to display structured data for printing or viewing.
  • Database Management Systems (DBMS): Computerized systems for creating, modifying, storing and extracting data from databases.

Types of Databases

  • Flat-file database: Data stored in simple files with fields but no structured relationship between them; -Example: Microsoft Excel (simplest form)
  • Relational database: Data is organized in interconnected tables using common fields. -Example: Microsoft Access, Microsoft SQL, Oracle, MySQL

Creating a Database in Microsoft Access

  • Templates: Existing templates can be used to create new databases faster.
  • Blank database: Enables creation of a completely new database from scratch.

Views

  • Design View: Defines fields, data types, and descriptions for tables; used for altering table definitions.
  • Datasheet View: Used for entering/viewing data; resembles an Excel spreadsheet interface.
