Session 3: FAQs and Related Articles
FAQs:
1. What is the difference between a relational and a NoSQL database? Relational databases use tables with structured data, enforcing relationships between data. NoSQL databases offer flexible schemas and scalability for large datasets but might lack data integrity features.
2. What is SQL and why is it important? SQL is a standardized language for managing and manipulating data in relational databases. It's crucial for querying, updating, and managing data efficiently.
3. What is normalization and why is it important in database design? Normalization is a process to reduce data redundancy and improve data integrity. It organizes data to avoid anomalies during insertion, update, and deletion operations.
4. What are ACID properties in database transactions? ACID (Atomicity, Consistency, Isolation, Durability) properties ensure data integrity and reliability during database transactions.
5. How do I choose the right database for my application? The choice depends on factors such as data structure, scalability requirements, transaction needs, and budget constraints.
6. What are some common NoSQL database types? Key-value stores, document databases (MongoDB), graph databases (Neo4j), and column-family stores are prevalent NoSQL types.
7. What is data warehousing and how is it related to database systems? Data warehousing involves storing and managing large amounts of historical data for analysis and reporting, usually utilizing specialized database systems.
8. What is the role of a database administrator (DBA)? A DBA is responsible for the design, implementation, maintenance, and performance tuning of database systems.
9. What are some career paths in database management? Careers range from database developer and administrator to data analyst and data scientist, each with varying levels of required skills and experience.
