models. For the following information, see the Emil Eifrem blog and NoSQL database description. Document Database Inheritance: inspired by Lotus Notes. Data Model: document summary, including key-value summary. Instance: CouchDB, MongoDB Advantages: Data Modeling is natural, programmers are easy to use, the development process is short, the webpage mode is compatible, and CRUD (short for adding, querying, updating, and deleting) is easy to achieve ).

Intelligence Nosql databases have evolved to meet the expansion needs of modern Web 2.0 applications. Correspondingly, most of their feature sets are designed to meet the needs of these applications. HoweverProgramThe value of data in is beyond the period of insertion, reading, update, and deletion of a typical web application. mining information from the company's database to improve the company's effic

Although the 09 appeared a more radical article "Relational database is dead", but we all know that the relational database is actually alive and well, you can not use the relational database. But it also illustrates the fact that the relational database has a bottleneck when it comes to processing WEB2.0 data.So are we using NoSQL or relational databases? I don't think we need to have an absolute answer. W

. Delete secondary indexes of a table, rewrite the query so that it only uses the primary key index; 7. Database sharding; this method is complex and costly to maintain; and it is costly to re-split when the data size increases again, limited secondary scalability; Ii.

With more than 10 years of architecture and development experience in C ++ and JavaJEE, MichaelKopp specializes in the architecture and performance of large-scale product deployment. Traditional enterprise database providers often propose that NoSQL lacks professional monitoring and management tools. Their argument is that enterprise applications need to fine tune and monitor Databases Michael Kopp has more

The difference between NoSQL and NoSQL is much greater than the difference between different SQL databases. Therefore, software architects must select a suitable NoSQL from the very beginning of the project. The difference between NoSQL and

adapt to the document database than other models, except for graph database [NOTE 1]. Obviously, graph database implements most of the common performance of a graph. In addition to the SQL field, I always recommend that you and your team do not underestimate the fact that you and your team are losing most of the tested tools and expertise that you are unconsciously using every day. I have seen a lot of people extract very basic information from the NoSQL
