advantages of using mongodb

The advantages of MongoDB compared to relational databases:① Weak consistency (eventually consistent), to ensure the user's access speed:For example, in a traditional relational database, a count type of operation locks the dataset so that the exact value in the "current" case can be guaranteed. This is important in some cases, such as checking account information through ATM, but for Wordnik, the data is c

Compared with relational databases, MongoDB has the following advantages:① Weak consistency (eventual consistency) ensures the user access speed:For example, in a traditional relational database, a COUNT operation locks the dataset to ensure that the exact value is obtained under the "current" condition. This is important in some cases, for example, when viewing account information through an ATM, but for W

Any relational database that has a typical schema design that shows the relationships between the table and these tables. Although in MongoDB, there is nothing to relate to the concept.The advantages of MongoDB over RDBMS Schema: MongoDB is a document database, where a collection holds different files. The number

imagine that they can actually work together to compensate for each other's shortcomings:Memcached is suitable for saving value based on key, then sometimes we don't know what to read what key to do? I was wondering if MongoDB or database can be used as a raw data, this raw data is divided into the fields to be queried (index field) and the normal data field two parts, a large number of non-query fields in the memcached, small granularity to save, In

(This is the advantage of MongoDB compared to other NoSQL)⑥ Superior

Label:Tasting Key-value Database (ii) The advantages and disadvantages of--MONGODBMongoDB's name is taken from the middle five letters of the English word "humongous" and is a database open source project developed by C + + based on Distributed file storage. His file storage format is Bson (binary JSON), which makes it possible to efficiently store binary data, such as large objects such as images, videos, and so on. Since I am a centos x86_64 system,

It is a gradual process to collect my own understanding of MongoDB's advantages and disadvantages, or to reference or extract from other reliable online files, it also expands with my understanding of MongoDB. (1) MongoDB limitations 1. Uneven data distribution in cluster shards 2. Relatively Poor standalone Reliability 3. Large data volumes continue to be in

Higher write loadBy default, MongoDB is more concerned with high insertion speeds than transaction security. If you need to load a lot of low-value business data, such as log collection, then MongoDB will work well for your use case, but you must avoid using MongoDB in scenarios where high transaction security is requi

Here I have my own understanding of some of the advantages and disadvantages of MongoDB, or through other reliable web references or excerpts from the basis, this is a gradual process, but also with my knowledge of mongodb deepened and expanding.(1) The deficiencies of MongoDB1. Uneven distribution of data in cluster shards2, single-machine reliability is relativ

, encapsulation can be very simple without any other ORM. Your code is a guarantee for the future. It's easy to add more fields to your object. So, as the requirements change, you can quickly modify the code to accommodate it. MongoDB is enough to make me realize that it has the potential to change the rules of the game. This is why you should advocate using a new generation of document databases instead o

collection is similar to a table in a relational database (RDBMS), unlike it does not need to define any schema (schema).Mode Freedom (schema-free) means that for files stored in a MongoDB database, we do not need to know any of its structure definitions. If necessary, you can store files of different structures in the same database.The documents stored in the collection are stored in the form of key-value pairs. The key is used to uniquely identify
