# Post reading # a very practical architecture entry book. The content is profound and involves a wide range. It helps us establish an architectural design concept.
After reading this book, I put my post feeling at the beginning. Below are detailed reading notes.
# Reading Notes # We divide the concept of software architecture into two major schools: composition School and decision School.

As we all know, design principles are the cornerstone of design patterns. When the design principles are followed, the written code becomes very flexible and can cope with changes and be easier to maintain. Of course, it is not so absolute. Next, we will briefly introduce some basic design principles, and then introduc

Why:
1. the user does not need to understand the details of this object, but only needs to understand the interface of this object to interact with the database, which facilitates the user's use.
2. Design a DaO layer. All the above business layers call the DaO layer interface to realize

We started using our own network card, found that it is not possible, because the tablet's Android system does not support the driver download and installation features. After discussing with the classmates we contacted the teacher, received the factory sent the original network card, from then can use WiFi.V.

name. After successful matching, the offset of the file in SD is obtained. The 9-bit offset (512 bytes, one sector) is the position of the file. Fopen returns a handle that corresponds to a data structure. The structure generally includes the start position, length, and current read pointer position of the file. The record start position and length are used to prevent cross-border reading.

C language is a process-oriented language, just beginning to get used to, to now write the program will also be oriented process thinking impact. When it comes to object-oriented programming (Java), it's natural to add a variety of functions to a class, and then write all kinds of code in a class. But the disadvantage of doing so is tha
