nosql vs relational

. 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), hierarchical databases (such as LDAP) for a long time. Howe

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

The following is the translation Developers generally choose NoSQL databases based on subjective assumptions, or the incorrect idea of "relational database performance is inferior to NoSQL database. In addition, when selecting databases, develo

handles plus stdin, stdout, stderr, and so on is 20. 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 large number of third-party reporting and analysis tools

, and application scenarios. Different products have different functions. it is impossible to choose who to choose based on the data model. Which product has the characteristics you need most and which is the best. Assume that your application has the following requirements: Complex things. if you cannot afford the risk of data loss or want a simple transaction programming model, you can choose relational databases and grid databases.

data operations. I think enterprise-level NoSQL should support simple transaction operations. For example, operations in a transaction can only insert data, modify data, and delete data. Other operations executed in the transaction process will not be included in the transaction category, that is to say, non-transaction operations will not be rolled back during transaction rollback. If data in a table or tablespace involves transaction operations, th

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
