Design (29) Oles Online Examination System The online examination system oles is divided into two software for students and teachers. The following is the cover of the software used by the examinee. The cover of the software used by the server-side teacher is similar: Software
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
Freescale Network patrol database monitoring software, deep database software monitoringAs the most important part of the information system, the database plays a key role in the operation of the business system. The system primarily uses analog accessTo monitor the performa

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
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
The Software development documentation includes the software Requirements specification, the data request says has the book, the outline design specification, the detailed design instruction, the feasibility study report, the project development plan. ##** One: Software Req
Platform software, the platform software can be widely used in various fields of society and various industries, such as enterprises, schools, hospitals, etc., in addition to special requirements (hardware and external System interface, etc.), other parts can be implemented by application development tools, to achieve the application of non-programmable system construction. Prior to the construction of the
The design pattern (English pattern) is a solution to the recurring problems in object-oriented design. The term was introduced into computer science in the 1990 's by people such as Erich Gamma and others from the field of architectural design. The meaning of the term is also controversial. The algorithm is not a design
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
Database model (ID-PID): A father has many children, and a child has only one father, such a structure is a tree. In a database table, the ID and PID (parent_id) are designed. A tree is stored by ID and PID. From the object-oriented design point of view, in the tree node class is not suitable for PID, a node has 1 or 0 fathers, and 0 or children. So the
that the implementation technology at this layer seems to be the least characteristic of the medical industry. Regardless of the business entity in the industry, the relational model or object-oriented model can be achieved in the end, and then stored and queried. The design patterns in this layer are similar to those in other industries to support scalability and achieve better performance. However, the key to the application of these models lies in
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
Most developers with the experience of the growth, will enter a management position (team leader, of course, Bo Master only graduated for six months, not the development team leader, just in advance to share to everyone), need to be responsible for software system design (System function design and database

Single Responsibility principle: there should be only one reason for a class to change (ASD). I just learned to program, is to learn the C language introduction. 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
The entire software development process is a rather complex process. Instead of simply writing software on the other side by a few design engineers, we need to start from the beginning to the end, including many people and different experts, different specialties and different knowledge are combined to form a complete softwar

detailed modules for the operation module! After the two designs, we need to describe the modules first: 1. Write a processing instruction for each module; 2, provide an interface description for each module; 3. Determine the global data structure and local data structure; 4. Indicate all design constraints and restrictions; 5. Conduct a summary design review. 5. Finally,
