Data Fundamentals and Databases
π Data is defined as any information or fact, including names, addresses, images, or files, essential for the functioning of systems from local companies to governments.
πΎ A database acts as an electronic container for storing data, enabling easy access, modification, protection, and analysis.
π» Applications like Google, Instagram, and WhatsApp rely on databases to store and retrieve user information, whether on personal computers or large servers.
DBMS vs. Database
βοΈ A database is merely the container for data, while DBMS (Database Management System) is the software used to manage and interact with that data (e.g., storing, modifying, or protecting it).
π οΈ Users interact with the DBMS using specific languages (like SQL) to execute commands on the database.
π Popular examples of DBMS software include MySQL, PostgreSQL, MongoDB, and Neo4j.
Database Evolution and Types
πΎ The evolution started in the 1960s with file databases, followed by hierarchical and network databases, which struggled with complex relationships.
π Currently, relational databases (RDBMS) constitute over 74% of current usage, while non-relational (NoSQL) databases have grown popular due to massive data growth from social media.
π Major companies often use a combination of both relational and non-relational databases to handle vast amounts of user data.
Relational Databases (RDBMS)
ποΈ Data is stored in collections of related tables, composed of columns (defined by name and data type) and rows (records).
π Relationships between tables are established using keys, such as the foreign key constraint, allowing data retrieval across multiple, interconnected tables.
π» SQL (Structured Query Language) is the standard language used with RDBMS like Oracle, MySQL, and Microsoft SQL Server to query, store, and modify data.
Non-Relational Databases (NoSQL)
π§© NoSQL encompasses several categories designed for specific data management needs, including Key-Value, Document, Graph, and Wide Column stores.
π Key-Value Stores (e.g., Redis) are the simplest, storing data as a blob associated with a unique key, useful for configuration data.
π Document Databases (e.g., MongoDB) store data in structured documents (like JSON), where each document can have a unique internal structure.
π Graph Databases (e.g., Neo4j) prioritize relationships, storing data as nodes connected by edges, ideal for pattern searching like fraud detection.
Key Points & Insights
β‘οΈ Understand the distinction: the database stores data, and the DBMS manages it.
β‘οΈ Relational Databases rely on structured tables and SQL for complex, interconnected data common in financial institutions.
β‘οΈ For unstructured or relationship-heavy data (like social graphs), consider Non-Relational Databases such as Document or Graph stores.
β‘οΈ Oracle is noted as the most widely used relational database, while MongoDB leads among non-relational options.
