separate existing data. It is wise to use separate databases at the beginning and perform effective database management. If you have a website for selling books, you may have a list of authors, a list of book prices, and a list of current inventory and orders. As your business continues to grow, orders will continue to grow, and processing each order requires a lot of disk access. It is very likely that you will put all the orders in an accounting system one day. Now, place the order in an inde

unit: For C ++, every cpp file is a compilation unit. From the demo of the previous compilation process, we can see that each compilation unit is unknown to each other.Target file: The file generated by compilation contains all the code and data in the compilation unit in the form of machine code, as well as some other information.Next, let's take a look at the compilation process. We skip the syntax analysis and directly generate the target file. Suppose we have a 1. cpp file.Int n = 1; Void f

Problem: the number of columns is filtered out as few as possible so that we can see from left to right. These numbers are from small to large and then from large to small (Netease ). Solution:This is a dual-end Lis problem. It can be solved using the DP idea. The objective planning function max {B [I] + C [I]}, where B [I] is left to right, 0 ~ The number of I numbers must increase progressively. C [I] is from right to left, n-1 ~ The number of I numbers must increase progressively. The final r

You can use modifiers to modify a document, such as adding or deleting a document's key value. Using the modifier first to navigate to a document and then add the appropriate modification options, you need to use the UPDATE statement1. Modify the document $inc modifier>Db.users.findOne ({'name':'CD'}); {"_id": ObjectId ("584eafa97629396db95535da"), "name": "CD", "Sex": "M", "information": { "Age": at, "Address": "Shanghai"}}>Db.users.Up

the document will only have a part to be updated. Using an atomic update modifier makes this part of the update extremely efficient. The update modifier is a special key that specifies complex update operations, such as resizing, adding or removing keys, or manipulating arrays or inline documents.For example, to record website access, when someone accesses, you need to increase the counter, you can use the update modifier atomically to complete this increase:In PHP, $ represents a variable pref

Http://www.mongodb.org/display/docs/advanced?queries=advancedqueries-conditionaloperators: MongoDB update data syntaxIn the previous article "MongoDB query syntax", I introduced the common query syntax of MongoDB, and the update operation of MongoDB is a bit complicated. I will introduce it here based on my experience, let's take a look at MongoDB users. It is also convenient for future users to refer: Note: The syntax introduced in this article and the previous article is in the mongodbshell e
