The next processing is even more interesting. Because our products do not support direct connection to Oracle for data processing, we must first import the data to sqlserver, in the first analysis, we used the table with 0.33 million records. First, we used the
software environment can not be burned according to the process of the development stage, so the efficiency is too low and error-prone for large batches. The simpler, the more efficient the single operation, the less prone to error. The best way to do this is to solve it in one step. The recommended way to do this is:
Complete the layout and construction of the entire software environment ac

When you use a report tool to design a report, when using a parameter control, sometimes we want some of the parameter controls to not appear when the condition is not met, and then show when the condition is met, and then I'll teach you how to do it!
How the table software controls whether a parameter control is displayed based on conditions
One: Problem description
When using a parameter control, sometimes we want the partial parameter control to
"Data Recovery failure description"Company financial personnel for data maintenance, misoperation, in the financial software to initialize the data, because recently did not do backup, it caused a lot of financial documents lost.Because the financial data is very important,
Analysis of three levels of software development, analysis of software development levels
In the morning, I saw Mr. Guo Anding's microblog on Weibo. I also posted a new article on Weibo to write this article.
Fei xiaotong, a late Chinese sociologist, believes that culture should contain three levels: the first level
As with anything, software has its own process of gestation, birth, growth, maturation and decay, which is generally referred to as the "software life cycle". The software lifecycle is generally divided into 6 phases, namely planning, requirements analysis, design, coding, testing, operation and maintenance. The relati
Want to know the free data recovery software which works? The following will be recommended for free data recovery software, in the use of computers or mobile phones will inevitably mistakenly delete files, data, this time need data
and others after studying the reliability growth model based on NHPP, the model of S shape reliability growth based on modified NHPP was proposed for the S shape of the mean function. Can be expressed as:
The reason for introducing the S-type curve is that the failure data of the software presents an S-shaped curve, and it can be understood that the learning process of the Test team members is taken into a
Software static analysis and tool Klocwork Introduction
1. Software static analysis
Software static analysis does not need to execute program code, can discover the code quality and the security question, this technique can move t
information. The software requirement analysis should provide as much information as possible for the software to achieve functional requirements, so that software designers and Software testers do not need to contact the demand side. This requires that the
Test case design is one of the basic skills that testers must master, and it is also one of the difficulties. So how does a written test case evaluate effectiveness? Recently has been thinking about this issue, originally wanted to come to an article, but has been lazy, until now, the information on the Internet a lot, here on the combination of their own thinking to simply talk about their own views it.

In P2P technology, UPnP is often used to implement direct TCP transfer, but different devices have small differences, and the methods supported by different devices are not the same, in the process of software startup, in order to save system overhead and synchronization, the Timer class is used to realize the addressing and interaction of UPnP.
Experienced software developers know that

The technology of rogue software is varied. Any function may become a rogue technology, just like a weapon. If it is used, justice can be done. If it is used properly, it can be used as an accomplice to evil.
First, I started with some rogue Analysis in win32:
1. As a rogue software, the first thing I want to do is to run it in real time. For example, in the regi
Summary:
Using the historical defect data in the software to establish the classifier, the software flaw detection.
Multi-core learning (multiple kernel learning): Map historical defect data to high-dimensional feature space, so that the data can be better expressed;
-functional requirements, software reverse requirements, software design and implementation limitations, reading support information.The software requirement analysis should provide all the information that the software realizes the function requirement, so that the
, so the test cases are written based primarily on software requirements. In addition, should also comply with the relevant writing rules, norms and so on.
1.2 Test Case Development principles
The design principles for test cases include:
1) According to the principle: the main basis of the test case preparation is the requirement specification and relevant technical specification document provided by the project;
2) The principle of full coverage: th
