Progress Tracking
- The platform offers a Mastery Score™ to monitor learning progress.
- Users can observe improvements in their scores as they engage with flashcards and quizzes, promoting motivation and accountability.
Database Overview
- A database is an organized collection of data managed by a database management system (DBMS).
- DBMS software enables interaction with end users, applications, and the database to efficiently capture, analyze, and manage data.
- The combination of a database, DBMS, and applications is referred to as a database system.
Database Storage
- Small databases can be stored on traditional file systems.
- Large databases are often hosted on computer clusters or cloud storage solutions.
Database Design Considerations
- Database design includes data modeling, representation and storage efficiency, query languages, security, and privacy.
- Important aspects also involve distributed computing considerations, such as concurrent access and fault tolerance.
Database Management System Functions
- DBMSs perform four main functions:
- Data Definition: Creation and modification of data organization definitions.
- Update: Inserting, modifying, and deleting data entries.
- Retrieval: Selecting data based on criteria and providing it to users or applications.
- Administration: User management, data security enforcement, performance monitoring, and data integrity maintenance.
Types of Databases
- Relational databases emerged in the 1980s, modeling data in rows and columns within tables, primarily using SQL for interaction.
- Non-relational databases, referred to as NoSQL, gained traction in the 2000s and utilize various query languages.
Database Models and Systems
- The term "database" sometimes ambiguously refers to either the database itself or the associated DBMS.
- A DBMS allows for specific data access while managing the organization of the data.
- Database models dictate the principles adhered to by both databases and their DBMS.
Database Servers
- Database servers are dedicated computers designed to run DBMS and related software.
- They typically feature multiprocessor architectures, substantial memory, and RAID disk arrays for reliable storage.
- Large transaction processing environments sometimes employ hardware accelerators connected to servers via high-speed channels.
Market Considerations
- The extensive market for DBMSs influences computer and storage vendors to align product development with DBMS requirements.
- Databases and DBMSs can be classified by database models (like relational or XML), operating environments (from server clusters to mobile devices), and query languages used (such as SQL or XQuery).
