associated, and this model supports some graph structure algorithms. The differences between NoSQL and relational databases are summarized as follows: NoSQL database data models are generally closer to actual needs. When using relational databases, the question to be concerned is "what functions can be provided by databases", while

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

has been greatly weakened.Therefore, the relational database is less suitable in these more and more application scenarios, and the non-relational database to solve this kind of problem arises . NoSQL is a generalized definition of non-relational data storage. It breaks the unification of long-term relational database

NOSQL systems generally advertise a feature, that is, good performance. Why? After so many years of development in relational databases, various optimizations have been done very deeply. NOSQL systems generally use relational database technology. What factors have bound the performance of relational databases? We can look at this problem from the perspective of s

1. Maturity RDBMS has existed for a long time. nosql supporters think that their age is a symbol of their out-of-date, but for most CIOs (CIOs), the maturity of RDBMS can be reassuring. generally, RDBMS systems are stable and feature-rich. in contrast, most nosql alternatives are still in the pre-production environment stage, and there are a lot of key features to be implemented. Living at the cutting e

However, these NoSQL databases may not be the most suitable for you. Most common applications can still be developed using traditional relational databases. NoSQL databases are still not

evaluation may be biased ......), In addition to this obvious fact, I have noticed that PostgreSQL is a surprising product. In this regard, I recommend it as one of the most urgent and optimal solutions for most data storage problems. Well-known enterprises with extraordinary performance requirements are investing heavily in PostgreSQL. However, my opinion here is slightly different: I asked myself whether most companies correctly view the "NoSQL" so

that the MySQL market value will reach $664 million in 2015, and the CAGR is "healthy" by 40%.As you can see, the only "unhealthy" factor in this chart above is the rapid rise of nosql. Aslett pointed out that 12.7% of the abandoned MySQL enterprise directly into the embrace of NoSQL, but this has little impact on MySQL installation base. The most common MySQL replacement is actually PostgreSQL. But even P

When talking about the data scale, we have to say that in the NoSQL market, the four most popular NoSQL systems are MongoDB, Redis, Cassandra, and HBase. We know that both Cassandra and HBase are BigTable systems and are well-known (with strong support from Facebook, Yahoo, and Twitter ). So why is MongoDB the most popular? Is HBase not g
