Html5 web storage and html5web Storage
Html5 provides two methods to store data on the client:
1: localStorage-data storage with no time limit
2: sessionStorage-data storage for a session
Of course, before that, this was all done by cookies, but you may have thought that cookies are not suitable for storing big data. C
Comments: In fact, in addition to sessionStorage and localStorage, HTML5 also supports local data storage through local databases. HTML5 adopts the "SQLLite" file-type database, which is mostly concentrated on embedded devices, if you are familiar with IOS/Android development, you should be familiar with SQLLite databases. In the previous HTML5 local Storage Web Storage
Character encoding system of MySQL (I)-data storage coding and mysql Data Storage
MySQL has been installed many times, and every time it will be entangled in the character encoding configuration of the database, so I decided to thoroughly clarify it this time.
The character encoding structure of MySQL is relatively small. It consists of two parts: Data Storage en
Android-based file data storage and android-based Data Storage1. Introduction to file storage data
Activity provides the openFileOutput () method to output data to a file. The specific implementation process is the same as saving data to a file in the J2SE environment. Files can be used to store a large amount of data, such as text, books, and audio.
The File object is suitable for reading or writing large

In the previous article web storage of HTML5 local storage, we briefly introduced how to use localstorage to implement local storage. In fact, apart from sessionstorage and localstorage, HTML5 also supports local data storage through a local database. HTML5 uses a file-type database such as "SQLite", which is mostly co

Sequential storage is converted to linked storage:

The Web Storage in HTML5 includes two ways of storage: Sessionstorage and Localstorage.Sessionstorage is used to store data locally in a session, which can only be accessed by a page in the same session and destroyed when the session ends. So sessionstorage is not a persistent local store, only session-level storage.While Localstorage is used for persistent local storag
modified or updated. In general, this latency is very small. Most locking mechanisms are designed to prevent multiple processes from updating the same data. Because inserting and updating information to data both needs to be locked, you can imagine that multiple applications may have a great impact on using the same database.
Different storage engines Support locking at different object levels, and these levels affect information that can be accessed
Web Storage is a very important feature introduced by HTML5. It can store data locally on the client, similar to the cookie of HTML4. However, it has more powerful functions than cookies, the cookie size is limited to 4 kb, and the Web Storage officially recommends 5 MB for each website.
There are two types of Web Storage:
• SessionStorage• LocalStorage

first, the definition of linear table:
(1) Concept definition: A finite sequence of data elements is called a linear table; the type of a data element in a linear table can be a simple type, or it can be a complex type. Many of the basic operations involved in practical application issues are very similar and should not be programmed separately for each specific application. Abstract the logical structure and basic operation (abstract data type) of generality from concrete application, then imp
