Label:The IT world is embracing "big data" quickly. Huge data storage will be the next topic of big Data analytics, as big data is getting bigger, for example, startups are using these systems to analyze the history of human evolution with trillions of DNA testing strips. While big data (and its underlying technology NoSQL) is becoming a buzzword in the information systems community, there is not much discussion about the security implications of big

Is NoSQL true or not? To NoSQL or not toNoSQL With the emergence of a large amount of data, NoSQL database architecture is being used by more and more people, because NoSQL architecture is more effective in big data processing. Today, when you need to store and process high-capacity data, many young developers prefer o

10 things you should know about NoSQL Databases Since the 1/4 century, relational databases (RDBMS) have been the mainstream database models. But now non-relational databases, "Cloud" or "NoSQL" databases, are gaining an increasing share as an alternative database model. In this article, we will focus on the 10 key features of non-relational NoSQL databases: the

Couchdb, as part of the nosql trend, is easy to compare with the database labeled with buzzwords. Key-value stores, tuple stores, bigtable clones, document store, graph database, and other labels are attached to each category. These classification labels sometimes help programmers outline the technical properties of the latter segment, but in many cases, the programmer's preference may be wrong and biased. We can say that these new technologies all w

traditional relational database point of view, the word "transaction" means that we first use the INSERT, Update, delete and other commands to exercise different tables, and then commit the modification with commit or rollback with the rollback command. NoSQL databases typically do not have these mechanisms: their write operations either succeed or fail. The "Transaction" at "Single Document level" is called "Atomic Transaction". Transactions for su
