With regard to NoSQL and SQL, it is well known that NoSQL only allows data to be accessed in restricted predefined modes. For example, DHT (Distributed Hash Table) is accessed through the Hashtable API. Other NoSQL data service access modes are also restricted. Scalability and performance structures are therefore predictable and reliable. In SQL, access patterns are not known beforehand, SQL is a common language that allows data to be accessed in a variety of ways, and programmers have limited control over the execution capabilities of SQL statements. In other words, in s ...

What is the real difference between NoSQL and SQL? Essentially, because different access patterns lead to differences in NoSQL and SQL scalability and performance. NoSQL only allows data to be accessed in restricted predefined modes. For example, DHT (Distributed Hash Table) is accessed through the Hashtable API. Other NoSQL data service access modes are also restricted. Scalability and performance structures are therefore predictable and reliable.
