NoSQL data model (4) Summary of nosql aggregation, NoSQLBackground in the first three articles, we have introduced three databases that belong to the aggregation model in NoSQL: Key-value type, document type, and column family type. The following analyzes the common points and differences of the three aggregate data models to better understand their respective ch

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 than 1 times, 5 minutes more than 10, 11 minu

[ArticleAuthor: Sun Li link: http://www.cnblogs.com/sunli/ updated by: 2011-2-21] The previous two articles, "Why use nosql" and "relational database or nosql Database", roughly introduced why nosql should be used and when nosql should be used. I often feel confused when I see the introduction of

a large change to the schema will be very complex. In a NoSQL database, data can be added at any time. You do not need to define documents and collections beforehand. For example, in MongoDB, the following action will book recreate a document in the collection if it was not previously created.Db.book.insert ( 9780994182654, "Jump Start Git", "Shaumik Daityari" , " ebook ", 29.00 ); (MongoDB adds a unique _id to each document in the collect

The previous "Why Use NoSQL" and "relational database or NoSQL database" two articles generally explain why NoSQL is used, and when to use NoSQL. Often have friends encounter confusion, see the introduction of NoSQL, feel very good, but do not know how to formally use their

Do you really understand the nosql world ?, Nosql world Recently, I want to sort out my nosql knowledge and some nosql databases. One is to deepen your understanding of nosql, and the other is to organize your knowledge to make it more organized. So I started to

NoSQL architecture practice (I)-supplemented by NoSQL (1) using NoSQL as an image It does not change the original architecture that uses MySQL as the storage, uses NoSQL as the auxiliary image storage, and uses the advantages of NoSQL to help improve performance. Figure 1-

document that contains extensions that support the data type representation of the JSON specification. It contains support for the JSON structure, such as arrays and nested objects (one document is contained in another document or array). The Bson document in MongoDB has no schema, which makes it possible to build a collection of documents that contain different structures. The flexibility of the document structure is useful in a number of areas, such as where data has different but similar at

There are practical, historical, and commercial reasons to explain the development of these stacks-but they cannot be thought of as rules. You can use MongoDB NoSQL databases in your PHP or. NET projects. You can connect to MySQL or S

The reason for writing this article is that mysql5.6.2 suddenly launched the memcached function. The emergence of nosql to InnoDB with memcached shows that nosql has indeed had a huge impact on relational databases. I personally think this is a huge improvement, allows developers to use nosql and relational databases more conveniently.

Differences between NoSQL and SQL: NoSQL and SQL. About the difference between NoSQL and SQL, NoSQL and SQL simply put: SQL is a structured query language for relational databases, while nosql generally refers to relational databases, and SQL statements cannot be used, no di

MongoDB-NoSQL, nosql Comparison between mongoDB and SQL: The biggest difference from a common database is structured and unstructured. NoSQL: Generally, it refers to non-relational databases. Compared with relational databases, in fact, its previous evolution is a data organization combined from a two-dimensional table and its relationships. A two-dimensional tab

transaction changes A, then the B must be changed so that the transaction will still satisfy a+b=10, otherwise the transaction fails.3, I (isolation) IsolationThe so-called independence refers to the concurrent transactions do not affect each other, if one transaction to access the data is being modified by another transaction, as long as another transaction is not committed, the data it accesses is not affected by uncommitted transactions.For example, there is a transaction from a to 100 yuan
