Our general solution is to design four tables that take advantage

Now, we use the above stored procedure to compute all child nodes and corresponding layers of the node Fruit. The query results are as follows: From the above implementation, we can see that the design scheme using Left and Right Value encoding is used. In the tree query time, only two database queries are required, eliminating recursion, in addition, the query conditions are numerical comparisons, and t

For example: { 9780992461225, "Javascript:novice to Ninja", "Darren Jones", "ebook", 29.00, "Learn JavaScript from scratch!" , " 5/5 ", review: [ " A Reader ", Text:" The best JavaScript book I ' ve ever read. " }, "JS Expert", Text: "Recommended to novice and Expert developers alike." } ] } The table structure in SQL has strict data schema constraints, so it is difficult to store data with errors.

design is to be able to transparently use the node to expand. The NoSQL database is typically designed to take advantage of low-cost commercial hardware. 2: Large Data Just as the transaction rate has increased over the past 20 years, the size of the stored data has increased enormously. O ' Reilly wisely called the phenomenon "the industrial revolution of dat

We design relational database schemas with a complete set of solutions, but NoSQL does not. Half a year ago I read this "SQL anti-mode" book, feel very good. Just start to notice, is there an inverse pattern for nosql? A good counter pattern can be used in our design

When talking about the data scale, we have to say that in the NoSQL market, the four most popular NoSQL systems are MongoDB, Redis, Cassandra, and HBase. We know that both Cassandra and HBase are BigTable systems and are well-known (with strong support from Facebook, Yahoo, and Twitter ). So why is MongoDB the most popular? Is HBase not g
