Software Engineering has a process-oriented and object-oriented approach, as well as process-oriented and object-oriented approaches to demand analysis, both of which are ways to know the world. What is a process-oriented process that sees the world as a related, there are a lot of inseparable or causal relationships of small system composition, this method is very useful in the low complexity of requirements, we have each small system start and end and each step and impact are defined, then can define the whole system behavior. But if the demand becomes complicated, it's very difficult to consider all the factors completely and simulate them ...

Object-oriented encapsulation of change, or more accurately, should be encapsulated in the same place, leaving a change in the place can be changed when needed, then where will change? 1, data changes such as a factory to produce a paper box, program to calculate its volume, need to have a long, wide, high size, the size of the box is fixed, then in the code directly hard coding, such as Long 1, Width 2, high 3, method to return 1*2*3, or even directly return 6, without any problems. Now the demand has changed, the factory produces two sizes of boxes, the other ...

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...
