standard for high-availability and PB-scale databases" as the goal of Hypertable. In other words, Hypertable is designed to reliably store large amounts of data across multiple cheap servers.5. Redis This is an open-source and advanced key-value storage. Because hash, set, string, sorted set, and list are used in the key, Redis is also called a data structure server. This system can help you perform atomic operations, such as adding hash values, intersection operations of sets, string concatena

Spring Data IntroductionThe Spring data project is a package of solutions that spring uses to solve data access problems. Spring data contains a large number of relational and non-relational database access solutions. Spring data enables us to quickly and simply use common data access technologies and new data access technologies.Spring data contains the following sub-projects:Spring Data JPA Org.springframework.data Spring-data-jpa 1.8.1.RELEASE

1. What is Springdata. The Spring Data project is designed to simplify the building of data access counts based on the spring framework application, including non relational databases, Map-reduce frameworks, cloud data services, and so on, and also includes access support for relational databases. Spring Data contains multiple subprojects: Commons-Provides a shared infrastructure for use by subprojects to support cross-database persistence Hadoop-a MapReduce job based on Spring's Hadoop job co

Database (graph)The graphical structure of the database is different from the other columns and the rigid structure of the SQL database, it is using a flexible graphical model, and can be extended to multiple servers. NoSQL databases do not have a standard query language (SQL), so database queries require a data model. Many NoSQL databases have rest-type data interfaces or query APIs. such as: neo4j, Infogrid, Infinite Graph. Therefore, we summari

that are unique to nosql, but are useful for real-world NoSQL modeling. Data copying and de-normalization are the one-class citizens. Relational databases are not very convenient when modeling and processing hierarchical or graphical data. The graphics database is clearly the perfect solution for this field, but in fact most nosql are very good at solving such problems. That's why this article has written a separate chapter for hierarchical data modeling. Although data modeling techniques are l

NoSQL databases have rest-type data interfaces or query APIs.[2] such as: neo4j, Infogrid, Infinite Graph. Therefore, we summarize the NoSQL database in the following cases, the comparison is applicable: 1, the data model is relatively simple, 2, the need for more flexible IT systems, 3, the database performance requirements are high; 4, There is no need for a high degree of data consistency; 5. For a given key, it is easier to map a complex value en
