Databases Demystified: From SQL to NoSQL Databases help apps store information reliably. Two broad families dominate: SQL databases, which use tables and fixed schemas, and NoSQL databases, which include documents, key-value pairs, wide columns, and graphs. SQL favors structured queries and strong consistency, while NoSQL often offers more flexible data models and easier scaling. This post summarizes the core ideas, helps you compare options, and avoids common myths about which choice is better in every case. ...

Databases demystified SQL vs NoSQL and beyond Databases come in many shapes. The classic SQL relational model stores data in tables with fixed schemas and uses SQL to read and update it. NoSQL covers several non-relational styles and often favors flexibility and scale. Most teams choose based on current needs and future growth. Relational databases and SQL SQL databases excel at structured data, strong consistency, and powerful joins. They enforce ACID transactions, which makes them reliable for money, inventory, and order systems. Popular choices include MySQL, PostgreSQL, and SQL Server. They also support rich querying, indexing, and mature tooling. ...

Databases 101: From SQL to NoSQL Databases help apps store and retrieve data. There are many styles, but two families dominate: SQL databases, which are relational and structured, and NoSQL databases, which cover non relational models. This post keeps things simple and practical, so you can choose with confidence. SQL databases organize data in tables with columns and rows. They enforce a fixed schema, support powerful queries, and aim for strong accuracy through ACID rules (Atomicity, Consistency, Isolation, Durability). If your data fits a clear structure—customers, orders, products—and you need precise relationships, SQL is often a solid choice. ...
