The snowflake schema is in the same family as the star schema logical model. In fact, the star schema is considered a special case of the snowflake schema. The snowflake schema provides some advantages over the star schema in certain situations, including: Some OLAP multidimensional database modeling tools are optimized for snowflake schemas. [3]
MySQL Cluster, also known as MySQL Ndb Cluster is a technology providing shared-nothing clustering and auto-sharding for the MySQL database management system. It is designed to provide high availability and high throughput with low latency, while allowing for near linear scalability. [ 3 ]
Starting with MySQL Workbench 5.2 the application has evolved to a general database GUI application. Apart from physical database modeling it features an SQL Editor, database migration tools, and a database server administration interface, replacing the old MySQL GUI Tools Bundle.
A database shard, or simply a shard, is a horizontal partition of data in a database or search engine. Each shard may be held on a separate database server instance, to spread load. Some data within a database remains present in all shards, [a] but some appear only in a single shard. Each shard (or server) acts as the single source for this ...

If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1250 ahead. Let's start with a few hints.
In databases, a term for the part of a database on a single node is a shard. A SN system typically partitions its data among many nodes. A SN system typically partitions its data among many nodes. A refinement is to replicate commonly used but infrequently modified data across many nodes, allowing more requests to be resolved on a single node.
Database partitioning is normally done for manageability, performance or availability [2] reasons, or for load balancing. It is popular in distributed database management systems, where each partition may be spread over multiple nodes, with users at the node performing local transactions on the partition. This increases performance for sites ...
