Types of Software Testing
Types of Database
1. Relational Databases (e.g., MySQL, Oracle, SQL Server): – Uses structured tables to store data. – Offers data integrity and complex querying capabilities. – Known for ACID compliance, ensuring reliable transactions. – Includes features like foreign keys and security control, making them ideal for applications needing consistent data relationships.
2. Document Databases (e.g., CouchDB, MongoDB): – Stores data as JSON documents, providing flexible schemas that can adapt to varying structures. – Popular for semi-structured or unstructured data. – Commonly used in content management and automated sharding for scalability.
3. In-Memory Databases (e.g., Apache Geode, Hazelcast): – Focuses on real-time data processing with low-latency and high-speed transactions. – Frequently used in scenarios like gaming applications and high-frequency trading where speed is critical.
4. Graph Databases (e.g., Neo4j, OrientDB): – Best for handling complex relationships and networks, such as social networks or knowledge graphs. – Features like pattern recognition and traversal make them suitable for analyzing connected data structures.
5. Time-Series Databases (e.g., Timescale, InfluxDB): – Optimized for temporal data, IoT data, and fast retrieval. – Ideal for applications requiring data compression and trend analysis over time, such as monitoring logs.
6. Spatial Databases (e.g., PostGIS, Oracle, Amazon Aurora): – Specializes in geographic data and location-based queries. – Commonly used for applications involving maps, GIS, and geospatial data analysis, including earth sciences.

Network Protocols
- HTTP (Hypertext Transfer Protocol): The foundation of data communication on the web, HTTP allows web pages to be requested and delivered across the internet.
- HTTPS (Hypertext Transfer Protocol Secure): An extension of HTTP, HTTPS adds a layer of security by encrypting data, making it safer for sensitive transactions online.
- FTP (File Transfer Protocol): A protocol used to transfer files between computers over a network, FTP is essential for managing and sharing large amounts of data.
- TCP (Transmission Control Protocol): Ensures that data sent over the internet arrives intact and in the correct order, making it reliable for most applications.
- IP (Internet Protocol): The addressing system for the internet, IP assigns unique addresses to devices, enabling them to be identified and communicate with each other.
- UDP (User Datagram Protocol): A faster but less reliable protocol compared to TCP, UDP is ideal for applications where speed is critical, like gaming and video streaming.
- SMTP (Simple Mail Transfer Protocol): The protocol responsible for sending emails across networks, ensuring messages reach their intended recipients.
- SSH (Secure Shell): A protocol that provides secure access to remote computers, widely used for system administration and secure data transfers.
- IMAP (Internet Message Access Protocol): Allows users to access and manage their email on a remote server, making it easier to sync messages across multiple devices.
