Prepare to develop a website for an e-store in your spare time. You must be able to cope with large data volumes and high concurrency. I will record the entire process of implementation and share it with you through my blog. Of course, the website of this e-store will also be open-source for free at the end. I hope you can make a lot of bricks.
What functional modules are our e-stores ready to implement?

MySQL stores logs and uses Loganalyzer for front-end display
Why use logs?In the production environment, we may need a complete log system to view the status and operations of the running host service, we can use ELK in a larger network architecture to collect, retrieve, and display logs at the front end, however, in small and medium architectures, rsyslog is enough to collect and retrieve logs from all servers for real-time data traffic analysis.

This skill may not be worth mentioning to anyone who is familiar with it. But I think, since these are common functions, it also makes sense to integrate them together to take notes.
First, json is the de facto standard for data transmission. So let's start by downloading it from the server .. Net Library is excellent, which is one of the reasons why I like X

Javascript: stores and reads cookies, and javascriptcookie
Cookie is an important technology in Web development. It is used to store some information locally (such as username, password, and logon status) so that users can use it for the next visit (or use it on other pages ). The cookie format is a key-value pair. Multiple key-value pairs are separated by semicolons, for example, name = zhangsan; age = 21.

IOS development Note 9: NSUserDefaults stores custom object, iosnsuserdefaults
NSUserDefaults is often used to locally store some simple data, such as user information. NSUserDefaults supports floats, doubles, integers, Booleans, URLs,NSData,NSString,NSNumber,NSDate,NSArray,NSDictionary. In addition, to store other types of data, you must convert the data to NSData before storing it.
First, inherit the NSCoding protocol from the custom object, and t
Android stores and loads local files (external storage devices) and android storage devices
Sometimes the application needs to write data to the external storage of the device. If you want to share music, images, or online data with other apps or users, it is easier to share data stored on external devices. In addition, external devices usually have larger storage space.
You can use android. OS. Environment. getExternalStorageDirectory () to obtain th
Android stores and loads local files (internal storage devices) and android storage devices
All applications on Android devices have a directory of files placed in the sandbox. Saving the files in the sandbox can prevent other applications from accessing them.
The full path of the sandbox directory is/data/
As you can see, each application has a file directory named after this package under/data.
This article describes how to save files in the/data/
Today, we will introduce the SYS. all_ SQL _modules view in SQL Server, which stores definition statements such as functions, tables, stored procedures, and views.
SYS. all_objects view, which contains the names of all objects (function name, table name, stored procedure name, view name, (main/foreign) key name, and index name ).
In this view (SYS. all_objects), we are concerned with the following columns:
