In the past, MySQL databases were used to write a large pile of SQL statements all day long. It took several days to remember these SQL keywords, and all the SQL keywords were written. When MongoDB was exposed, I found that I don't need to write SQL statements. I instantly felt that I was so tall that I was eager to learn how to use it. 1.

compensate for the relational database in some aspects, and gradually most companies have put some of the business data inventory into NoSQL, such as MongoDB, HBase and so on. The data storage aspect uses the Distributed file system, such as HDFs, GFS and so on. Massive data analysis uses Hadoop, Spark, Storm, and more. These are related to the operation and maintenance of cutting-edge technology, but also

This series of articles will be popular to introduce its many uses. In this series of previous articles, we looked at the work of completing a job step using a proxy account that mimics the Windows security context. Most subsystems support proxy accounts, while subsystems restrict proxy accounts, requiring users to explici

Label: Mongo DB is a non-relational database (NOSQL) that is currently very popular in the IT industry, and its flexible data storage methods are highly favored by current it practitioners. Mongo DB is a good implementation of object-oriented thinking (Oo idea), in Mongo db each record is a document object. The biggest advantage of Mongo DB is that all data persistence requires no developers to write SQL statements manually, and it is easy to invoke methods to implement CRUD operations.Tools/Mat
