Study Notes
Basic Concepts in Database Management
- The smallest unit of data a computer can handle is a bit, which represents a single binary digit that can have a value of either 0 or 1.
Database Terminology
- A group of related fields, such as a student's name, course taken, date, and grade, is referred to as a record or tuple.
Limitations of Traditional File Environment
- Data redundancy and inconsistency in the traditional file environment occur when multiple copies of the same data are stored in different files, leading to inconsistencies and inefficiencies.
Data Redundancy
- Data redundancy refers to the presence of duplicate data in multiple data files, which can lead to inconsistencies and inefficiencies.
Data Entity
- A data entity represents a person, place, thing, or event on which information is stored and maintained.
Database Management Systems (DBMS)
- A major capability of DBMS is to store, retrieve, and manage large amounts of data efficiently and effectively.
Relational Database Management Systems (RDBMS)
- What makes a relational DBMS powerful is its ability to store data in tables with defined relationships, enabling efficient querying and manipulation of data.
Database Design Principles
- A key principle to consider in database design is data normalization, which ensures that each piece of data is stored in one place and one place only.
Business Intelligence and Data Analytics
- The principal tools and technologies used for accessing information from databases to improve business performance include business intelligence, data mining, and data analytics.
Data Resource Management
- Information policy, data administration, and data quality assurance are essential for managing the firm's data resources because they ensure data accuracy, completeness, and security.
