Study Notes
Database
- A database is a collection of organized information that enables efficient retrieval and manipulation of data.
- Databases are designed to manage large amounts of data, making it a crucial tool for various industries.
Database Drivers
- A database driver is a software component that allows a program to interact with a Database Management System (DBMS).
Database Drivers Applications
- Open Database Connectivity (ODBC) is a standard for connecting to relational databases, enabling communication between applications and databases.
- Java Database Connectivity (JDBC) is a Java-based API for connecting to databases, providing a standardized way to access relational databases.
- PHP-Data Object (PDO) is a data access API for PHP, offering a secure and efficient way to interact with databases.
- Database API is Python's standard API for interacting with databases, providing a simple and consistent way to access and manipulate data.
Relational Database
- Relational databases store data in tables with rows and columns, enabling efficient querying and manipulation of data.
- They typically have a connection, which allows multiple tables to be linked and queried together.
- Also known as relational databases, they are widely used in various industries.
Non-Relational Database
- Non-relational databases, also known as NoSQL databases, do not have a fixed schema, allowing for flexible data storage.
- They do not have a connection, making them suitable for large-scale, distributed data storage.
Object-Oriented Database
- Object-oriented databases store data in the form of objects, which can contain both data and functions.
- They are suitable for applications that require complex data structures and object-oriented programming.
Hierarchical Database
- Hierarchical databases store data in a tree-like structure, with a parent-child relationship between data entities.
- They are suitable for applications that require a hierarchical representation of data, such as file systems.
Graph Database
- Graph databases store data in the form of nodes and edges, enabling efficient querying and manipulation of complex relationships.
- They are suitable for applications that require graph-based data structures, such as social networks and recommendation systems.
Network Protocol Notes
Response and Delivery
- Network hosts wait for a response based on specified rules
- Three types of message delivery:
- Unicast: One-to-one delivery
- Multicast: One-to-many delivery
- Broadcast: One-to-all delivery
Network Protocols and Standards
- Protocols: Rules that govern communications, implemented in software, hardware, or both
- Networking Protocols: Define a standard format and set of rules
Specific Protocols
- Hypertext Transfer Protocol (HTTP): Application protocol governing web server and web client interaction
- Transmission Control Protocol (TCP): Manages individual conversations
- IP: Encapsulates TCP
- Ethernet: Allows communication over a data link
Protocol Suites and Industry Standards
- Protocol Suites: Collections of protocols that cooperate
- TCP/IP: Open standard protocol suite
- Advanced Research Projects Agency Network (ARPANET): Predecessor to today's internet
