In the world of relational databases, joining tables on foreign keys is a common and well-understood practice. However, there are situations where you need to join tables based on non-foreign key fields. This might seem unconventional, but it can be a powerful technique when used appropriately. In this article, we will explore the concept of joining database tables on non-foreign key fields, and we'll demonstrate how to do it using Navicat.
Redis is a high-performance, in-memory data store known for its speed and versatility. One of its useful features is the ability to set expiration times for keys. Expiring keys in Redis is crucial for managing data and ensuring that outdated or temporary data is automatically removed from the database. In this article, we'll explore how to expire keys in Redis using the redis-cli and Navicat for Redis as well as how this feature can be applied in various scenarios.
In Redis, a Hash is a data structure that maps a string key with field-value pairs. Thus, Hashes are useful for representing basic objects and for storing groupings of counters, among other things. This article will go over some of the main commands for managing hashes, both via the redis-cli and using Navicat for Redis.
Redis supports several data types for storing collections of items. These include lists, sets, and hashes. Last week's blog article covered the List data type and highlighted some of the main commands for managing them. In today's follow-up we'll be turning our attention to the set type. In Redis, a Set is similar to a List except that it doesn't keep any specific order for its elements and each element must be unique. This article will go over some of the main commands for managing sets, both via the redis-cli and using Navicat for Redis.
