Some Insights About Databases

Dear Students ,
Ever felt lost in the sea of databases? SQL, NoSQL, NewSQLโ€ฆ Sounds like alphabet soup, right?

Letโ€™s simplify it! :raised_hands:

:one: ๐—ฆ๐—ค๐—Ÿ ๐——๐—ฎ๐˜๐—ฎ๐—ฏ๐—ฎ๐˜€๐—ฒ๐˜€: Think of these as the classic recipe! SQL databases like MySQL or Oracle use tables to store data. Itโ€™s the traditional, tried-and-tested approach.

:two: ๐—ก๐—ผ๐—ฆ๐—ค๐—Ÿ ๐——๐—ฎ๐˜๐—ฎ๐—ฏ๐—ฎ๐˜€๐—ฒ๐˜€: Welcome to the modern kitchen! NoSQL databases ditch the rigid tables and offer flexibility and speed. Different types cater to different tastes:

๐—ž๐—ฒ๐˜†-๐—ฉ๐—ฎ๐—น๐˜‚๐—ฒ: Like a simple dessert, itโ€™s all about pairs. Each โ€˜keyโ€™ leads you straight to its โ€˜valueโ€™. Redis is a superstar here.

๐——๐—ผ๐—ฐ๐˜‚๐—บ๐—ฒ๐—ป๐˜: Imagine storing entire recipes, not just ingredients. Thatโ€™s what MongoDB does - stores complete โ€˜documentsโ€™.

๐—–๐—ผ๐—น๐˜‚๐—บ๐—ป๐—ฎ๐—ฟ: Big dataโ€™s favourite dish! These databases, like Cassandra, store data by columns, ideal for data analytics.

๐—š๐—ฟ๐—ฎ๐—ฝ๐—ต: For data thatโ€™s as interconnected as spaghetti! Neo4j is a popular choice for these interconnected databases.

:three: ๐—ก๐—ฒ๐˜„๐—ฆ๐—ค๐—Ÿ ๐——๐—ฎ๐˜๐—ฎ๐—ฏ๐—ฎ๐˜€๐—ฒ๐˜€: ๐—œmagine taking grandmaโ€™s recipe (SQL) and giving it a modern twist (scalability of NoSQL). Thatโ€™s NewSQL, like CockroachDB.

:four: ๐—ฆ๐—ฝ๐—ฎ๐˜๐—ถ๐—ฎ๐—น ๐——๐—ฎ๐˜๐—ฎ๐—ฏ๐—ฎ๐˜€๐—ฒ๐˜€: Map-lovers, this oneโ€™s for you! Perfect for storing geographical data like maps (PostGIS).

:five: ๐—ง๐—ถ๐—บ๐—ฒ-๐—ฆ๐—ฒ๐—ฟ๐—ถ๐—ฒ๐˜€ ๐——๐—ฎ๐˜๐—ฎ๐—ฏ๐—ฎ๐˜€๐—ฒ๐˜€: Think of a time-stamped photo album, where every data point has a time-stamp. InfluxDB does this brilliantly!

:six: ๐—ข๐—ฏ๐—ท๐—ฒ๐—ฐ๐˜-๐—ข๐—ฟ๐—ถ๐—ฒ๐—ป๐˜๐—ฒ๐—ฑ ๐——๐—ฎ๐˜๐—ฎ๐—ฏ๐—ฎ๐˜€๐—ฒ๐˜€: Coding in objects? Store in objects! These databases match your object-oriented programming style.

Phew! Thatโ€™s quite a menu!

Just remember, thereโ€™s a database for every app, and knowing them helps you pick the right one.
