database is better suited to the case where data is organized through relationships, and a dedicated text search system is better suited to situations where real-time search is required.Here, let's look at the main advantages and differentiation features of the SQL system:* SQL enables interactivity. SQL is a declarative query language. Users say what they want (for example, to show the location of the top customers during the past March 5), the database internals algorithm and extracts the res

Low cost: This is the common feature of most distributed databases, because it is mainly open source software, there is no expensive license cost;But his flaws, the NoSQL database still has a lot of shortcomings, the common main has the following these several:1. Does not provide support for SQL: If the industry standard

-relational, distributed, does not provide an acid database design pattern.The No:sql (East) symposium, held in Atlanta in 2009, was a milestone with the slogan "Select Fun, Profit from Real_world where Relational=false;". Thus, the most common explanation for NoSQL is "non-relational", emphasizing the advantages of Key-value stores and documentation databases, rather than simply opposing RDBMS.Based on 2014 years of revenue, the

Comparison of eight Nosql database systems: KristfKovcs is a software architect and consultant who recently published an article comparing various nosql databases. The article was compiled by Tang youhua, an agile translator. For more information, see post-Article declaration. Although SQL database is a very useful tool, after 15 years of outstanding performance,

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 efficiency and competitiveness, as well as busines

Basic concepts of one or two peopleNoSQL, which refers to non-relational databases.Relational database is a database based on the relational model.The relational model is mentioned here,The relational model was proposed by E.f.codd in 1970.Compared with the level and mesh model, it has the following characteristics:1. Simple data structure (two-dimensional table)2. A solid theoretical basis.A. Relational operation theoryB. Relational model design theoryIn simple terms, the relational model refer

Its data shard model has strong disaster tolerance, so it realizes relatively loose weak consistency--the final consistency.Surdoc is the independent innovation of the scholar Company electronic document cloud service platform, it supports cloud service and mobile terminal, based on international standard UOML, is the only product in the world that allows users to read all format documents without installing Office, PDF or other

products, suppliers, and long-term technical support are all chips that attract their attention. Today, almost no one is willing to buy expensive software, but Standardization can still provide a good space for technological development. Why does NoSQL have to compete with traditional relational databases? The reason is that the competition for database-driven SPI (service programming interface) and API su

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

We design relational database schemas with a complete set of solutions, but NoSQL does not. Half a year ago I read this "SQL anti-mode" book, feel very good. Just start to notice, is there an inverse pattern for nosql? A good counter pattern can be used in our design schema to tell where traps and cliffs are. NoSQL propaganda often claims to be schemaless, which
