The sequential and chained storage of linear tables has different time complexity in storing and deleting data. Typical examples of sequential storage are arrays, and a typical example of chained storage is a single linked list. As we all know, when the reading data is more frequent, we choose the sequential storage mo

I. The concept and development of file system and database system1. File systemThe so-called file system simply says the software structure that is responsible for accessing and managing file information. For example, the computer's hard disk C, D, E, F, and movable storage devices. A file system is a method and data structure that the operating system uses to clear files on a disk or partition, that is, the method of organizing files on disk. Also re

[Html5] html5 local storage and html5 Storage I have been studying html5 for a long time, so I can reserve knowledge for future mobile projects. Compared with html4, html5 adds some interesting labels, attributes, and methods. Today we will introduce the local storage of html5.Store data on the client Html5 provides two new methods to store data on the client:

Last time, I was initially exposed to the mounting problem of Android USB client, so I wrote the first article about the feelings. There are still some problems in many places, some of which are not clear enough, so I want to continue writing. First, the last verification shows that the device can be mounted, but only one storage device can be mounted at a time. Secondly, what I said last time about the driver of the device node, there is also a probl

Windows Phone 7 supports data access in the following ways: XML, isolated storage [independent storage], and cloud [cloud storage]. Windows Phone 7 does not support local storage. Database APIs can be used. Isolated storage [independent

This article mainly aims to write some thoughts and insights on storage, because some things have been practiced by myself, so I feel more deeply, technically, I still think that the implementation is different from others' code. Let's assume a library. If we say that books are the data we want to put, how can we put them. The best way to do this is to drop it inside and then there is no rule, so that every time we look for a book, we will be exhauste
