I. Introduction: In the past few years, nosql databases have become synonymous with high concurrency and massive data storage solutions, and their corresponding products have sprung up. However, only a few products stand out, such as redis, MongoDB, berkeleydb, and couchdb. Because each product has different features, there are also some differences in their application scenarios. The following is a simple description: 1 ). berkeleydb is a very popul

This is only a matter of time: forced to use relational databases, but eventually found to be unable to adapt to the needs of the numerous.But the difference between NoSQL databases is far more than the differences between two SQL databases.

First, Introduction: 1, BerkeleyDB is a very popular open-source embedded database, in more cases can be used in the storage engine, such as BerkeleyDB before Oracle acquisition as a storage engine for MySQL, it can be foreseen that the product has excellent concurrency scalability, Supporting transactions and nested transactions, massive data storage and other important features, in the storage of real-time data for the very high value available.

the database recovery is very slow, it is not easy to quickly recover the database. For example, 4kb size of the text is close to the size of 40GB, if you can save this data from MySQL, MySQL will become very small. Relational databases are powerful, but they do not handle all the scenarios well. MySQL's poor scalability, big data under the IO pressure is very large, table structure changes difficult, this is the current use of MySQL deve

Label:NoSQL systems generally advertise a feature that is good performance and then why? relational database development for so many years, various optimization work has been done very deep, nosql system is generally the absorption of relational database technology, and then, what is the constraints of the relational database performance?

, primarily license fees and data access speeds. For social network applications like Facebook and e-commerce sites like Amazon, they need to process massive data. scalability and availability are key database requirements. Data can be distributed across hundreds or even thousands of servers. Now, many companies have switched to non-relational database management systems or non-SQL databases (NoSQL ). Howe

The most common explanation for NoSQL is that non-relational, or not-only SQL, can be seen from the field meaning that it refers to the generic term of a non-relational database.Background of the birth of NoSQLWith the development of the distributed architecture of large-scale Web sites, the use of traditional relational databases seems to be inadequate in the following ways:1, high concurrent read and write to the databaseWith the popularity of distr

A relational database (RDBMS) has been a mainstream database model for over One-fourth centuries. But now the relational database, "cloud" or "NoSQL" database, is gaining more and more occupancy as an alternative database model.
