What is the comparison between nosql and relational databases? Advantages: 1) Cost: nosql databases are simple and easy to deploy. They are basically open-source software and do not need to be purchased and used at the same cost as Oracle, which is cheaper than relational databases. 2) query speed:
Key-Value Store databaseTemporary: as memcached. The temporary key-value database stores the data in memory, which in two cases results in the loss of data, the first is the power outage, but the data content exceeds the memory size. The benefits of this treatment are very fast.Permanent type: such as Tokyo Tyrant, flare and RomaThe two are both types: Redis. Redis first data in memory, and then meet certain conditions (the default is 15 minutes more
