Atitit. Improved development efficiency --- the revolution of the MDA software development mode (3) ---- automatic table Creation 1. Automatically create table 1 after modeling 1. Traditionally, you need to create a table first, in the Business Code... 1 2. model-driven table creation-more simplification is to automatically create table 1 after modeling 2.

Title 53: The Software test object does not contain ().A. Software codeB. Software development processC. DocumentationD. DataAnalysis: The software test is not only the object of the program, but also should contain the corresponding documents and test data, the correct answer to choose B.Real Topic 54: The following

)Function,What functions does the software support? B)External interface,Does software interact with users, system hardware, other hardware, and other software? C)Performance,What are the performance of different software functions, such as speed, availability, response time, and recovery time? D)Attribute,How do we co

30-minute understanding of Object-Oriented Design Principles Many people have read the design patterns, but Martin does not have much estimation on the object-oriented design principles (For details, refer to Agile Software Development: Principles, models and practices). In fact, the two are complementary: the design pattern is a specific practical method, and the design principle is the guiding ideology; The design pattern lets you know how, and the

1. If a class has too many responsibilities, these responsibilities are coupled. Changes in one role may weaken or suppress this class's ability to fulfill other responsibilities. This coupling will put the fragile (fragile) design upside down, and when changes occur, the design will suffer unexpected damages. P88 2. In SRP, we define the responsibility as a reson for change ). P89 3. The changed axis is meaningful only when the change actually oc

unchangedSYesTChild type. 3.Dependency inversion principle (Dip) High-level modules should not depend on low-level modules. Both of them should depend on abstraction. Abstraction should not depend on details. Details should depend on abstraction. 4.Interface isolation principle (ISP) Do not force customers to rely on methods they do not need. Following the above principles can make our software m

entire program into multiple nodes to extend the hierarchical architecture, but the overall relationship is too tight, so it's hard to scale.Easy to be exploitativeRating: EasyAnalysis: In the development difficulty above, the hierarchical structure obtains the relatively high score. Because this architecture is familiar to everyone, it is not difficult to achieve. Most companies are developing projects that are differentiated by layers, a model that is appropriate for most commercial project d

Software developmentReferring to experiment two (LED), this experiment and experiment two (LED) difference is that the system clock from 50M to become 100M. Run the result, output hello from Nios ii! in the Debug window, and the four LED lights on the board flow display, indicating the test was successful! This experiment confirmed that the board support Operation frequency is high enough to reach 100M.Experiment Code /** "Hell

) O (M*P) Medium So so Medium So so Knn No No O (M*n) Slow Low Low So so Deep learningThe previous article has been explained. Deep learning is a combination of unsupervised and supervised learning algorithms. Therefore, it is not easy to determine the complexity of space-time.The model parameters of deep learning are generally independent of the data magnitude, but on the one hand, because it is less selective to

2.2 lazy acquisition mode The lazy acquisition mode delays the resource acquisition to the last point of the system execution, so as to optimize resource usage. 1. Problem Limited resource availability is a constraint on all software systems. In addition, if the available resources are not properly managed, it may cause bottlenecks to the system and significantly affect the system performance and stability. To ensure that resources are availa

Developers must add some changed code to the framework to grasp its actions, make the application a specific application in the domain. C.

Control the calculation problem by random number generation and subtraction (0-3 for subtraction respectively, if there is no multiplication, then 0 or 1 will be generated, thereby excluding the multiplication operation)5.
