NoSQL vs SQL в реальных проектах
Краткий обзор
SQL (реляционные СУБД): данные хранятся в таблицах со строго заданной схемой (schema-on-write). Пример: PostgreSQL, MySQL, Oracle.
NoSQL (нереляционные СУБД): гибкие модели данных (документ, ключ–значение, граф, колоночные) и отсутствие жёсткой схемы (schema-on-read). Пример: MongoDB (документы), Redis (ключ–значение), Cassandra (колоночная), Neo4j (граф).

There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
