The difference and relation between graph database and relational database

I recently used a graphical database to support a start-up project. In the process of using this kind of graphics database is actually very interesting. So here's a brief introduction to you.The NoSQL database is believed to have been heard. They can often be used to deal with a series of problems that traditional relational databases are difficult to solve. Typi

Graph database query based on multiple conversion Semantics

1. Summary Because of the complex pattern and different information descriptions of graph databases, it is extremely difficult for non-professional users to query complex graph databases. A Good Graph query engine should support conversion of synonyms, acronyms, abbreviations, and ontology, and should be able to sort search results well. Based on this problem, th

Open source software: NoSQL database-Graph database Cassandra

cite an extreme example. If we have a Cassandra cluster and it's made up of five physical machines. One of the physical machines is 4 times times the capacity of the other physical machines. Then setting the replication factor to 3 o'clock will cause the same data to be stored on a physical machine with a larger capacity. It's not much better than setting it to 2. So in determining the replication factor of a Cassandra cluster, we carefully set an appropriate value based on the number and

Tags: Things added will also be able to profit create a use maximumWhat is a graphic? A graph consists of two elements: a node and a relationship. Each node represents an entity (person, place, thing, category, or other data segment), and each relationship represents how two nodes are associated. For example, the relationship between the two nodes of cake and dessert is a point from cake to dessert. This versatile structure allows you to simulate a v
