Kristóf Kovács, a software architect and consultant, recently released an article comparing various types of NoSQL databases. Although the SQL database is a very useful tool, the monopoly is about to be broken after a 15-year solo show. It was only a matter of time: forced to use relational databases, but found that the inability to adapt to demand was too numerous. But the differences between the NoSQL d

Although a mixed-record structure is appropriate for non-relational or NoSQL APIs, because there is no pattern required, developers often face situations where a technique is needed to use a pattern. A consistent pattern definition for some software using SQL (or ODBC, etc.) is required, such as a

 NoSQL (NoSQL = not-only SQL), meaning "not just SQL"is a new revolutionary movement in the database, which was raised early on, and the trend is growing to 2009. NoSQL advocates are advocating the use of non-relational data storage, which is undoubtedly a new kind of thinking injection, relative to the overwhelming use of relational databases.

networking, and access to open and standardized data sources for a large number of disparate systems. Relational databases create more problems when dealing with these trends. This leads to the emergence of a large number of different techniques to address specific aspects of these problems, which can interact with or replace existing RDBMS-also known as hybrid persistence (Polyglot persistence). Database substitutes are not new, they have been in the form of object Databases (OODBMS), hie
