Design (26) Pascal Theorem Software Design Pascal's Theorem . Verification of more than 400 Special Cases 0. This is the cover of the vopt software, but it will be automatically deleted in just an instant. 0. The screen menu is displayed after the cover disappears. The function of the screen menu is the same as that

Agent Mode in software design mode; Agent Mode in Design Mode It seems that I have stopped the service for nearly half a month. It's really not the case. In the new year, I should keep myself at zero. Back To Zero. Let's start from this article. This article will introduce the basic concepts of proxy mode and the advantages and disadvantages of static proxy and

Abstract: The database is the foundation of the system. If you need to change the fields of the database frequently, or even modify the table and table relationship, I believe that no one will be able to cope with it several times! Because of the changes in the database structure, not only the changes in the database itself, but also the code at the entity, data operation, logic, and performance layers must be modified. What's more troublesome is that if a large amount of old data already exist

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. 6. fread The read operation is performed based on the current read pointer of the handle, and the cu

pointer array fops is registered in the system's API management array.6. The system is classified management of the drive, it has a record of each driver interface function pointer array Base address array, each driver in advance in order to contract, such as the first element of the group is the key driver Key_fops, and the second is the LCD driver lcd_fops, and so on. When a driver is loaded, the driver logs the corresponding FoPs through the API-managed interface to the corresponding locatio

Write the outline design instructions correctly Before the need is clear, ready to start coding, to do the outline design, and the detailed design may be most of the company did not do, and do most of it and coding synchronization, or after coding. Therefore, for most companies, the profile design document is the only

words, engineers produce documents, not physical objects. Others make physical objects according to these documents. As a result, I raised a question in my confusion: "Apart from all documents normally generated by software projects, are there other things that can be considered as real engineering documents ?" My answer is, "Yes, there is such a document, and there is only one source code ." Taking the source code as an engineering document-

Design (23) Graphic software design for Binary Functions This software is designed to create black-and-white illustrations for papers or textbooks. It uses gridlines to represent the 2-element function z = f (x, y). [Note: Actually, it is y = f (x, z), x, z is the independent variable. In this example, the funct

How to better design the software architecture is an eternal key topic in the software engineering field. Over the past few decades, the international software engineering community has made great strides in Software Architecture Design
