Eight years of experience using NoSQL Mike Bowers, an Enterprise Data architect at Jesus Christ's late Saints Church (LDS), introduced eight years of experience using NoSQL databases at the recent Enterprise Data World Conference (EDW. He talked about the design basis for selecting a NoSQL database. If a large organization chooses to use a

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 large number of third-party reporting and analysis tools, including Crystal Reports and Excel, as wel

 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.

. 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. However, over the past few years, a number of new

Abstract: compared to traditional relational databases, NoSQL has more complex classifications-key values, document-oriented, column-based, and graph databases. Here's a list of NoSQL scenarios for various types and options for some well-known companies.In the past few years, relational databases have been the only choice for data persistence, and data workers are only looking at these traditional databases
