mongodb scalability

Label:MongoDB is a product between a relational database and a non-relational database, and is the most versatile and most like relational database in a non-relational database. The data structure he supports is very loose and is a JSON-like Bjson format, so you can store more complex data types. MONGO's biggest feature is that the query language he supports is very powerful, and its syntax is a bit like an object-oriented query language that almost implements most of the functionality of a rela

Detailed steps for deploying mongodb in LinuxApplication scenarios MongoDB is a distributed file storage-based database. Written in C ++. It is designed to provide scalable, high-performance data storage solutions for WEB applications. MongoDB is a product between relational databases and non-relational databases. It has the most abundant functions and features l

In the age of large data, the traditional relational database should be able to higher service must solve the problem of high concurrent read and write, massive data storage, high scalability and high availability. But it is because of these problems that NoSQL was born. NoSQL has these advantages: Large amount of data, you can store large amounts of data through a low-cost server, easily get rid of the traditional MySQL single table storage scale l

Written in front: MongoDB is a nosql non-relational database, a more popular product. In the data persistence and the association with the relational database is also done better, at present, the major companies in the storage of binary files (pictures, video, etc.) are widely used. It is also relatively simple to follow the Key-value data schema and object-oriented JSON statement usage. After that, I will share with you some of the experiences I have

. MongoDB has no concept of columns, rows, and links for tables in relational databases, which reflects the free mode. Ii. Features It features high performance, ease of deployment, and ease of use, making it easy to store data. Features: 1) oriented to centralized storage, it is easy to store object-type data. 2) Free mode. 3) supports dynamic query. 4) supports full indexing, including internal objects. 5) query is supported. 6) supports replicati

want to use a flat, tabular structure to hold the data, this can be difficult both in querying and fetching data. Example 1: Take a "dictionary item", although not very complex, but it will be related to "definition", "part of speech", "pronunciation" or "reference" and so on. Most engineers would use this model as a primary key and foreign key in a relational database, but wouldn't it be better to think of it as a "document" rather than a "series of relational Tables"? Using "dictionary.defi
