I like your point. Parallel implementation also requires a lot of time and requires frequent maintenance. This will slow down the company’s production speed because workers need to complete twice as much work as normal work within a period of time in order to achieve the same goals for both systems. This includes entering or changing the same data…[Read more]

After an organization acquires or develops a new system, it is important for the organization to deploy the system. In order to ensure that the new system can adapt to the production environment, the organization has three ways to replace the system.The first is the direct cutting method. This means that after immigrating all data to the new…[Read more]

good point. The parallel deployment method is to run the old system and the new system at the same time. Its price is higher because the company needs to operate two systems at the same time. However, this method is less risky because the new system needs to be prepared before it can be cut off.

I agree with you. When developers consider system deployment, they should consider the costs, time, and potential problems that they may encounter in the future. The direct method means that the old system is shut down when the new system starts

Good point .The parallel method refers to running the old information system and the new system before the management decides that the old system can be shut down. If the new system has a problem, the user can return to use the old system.

I agree with you. The company needs to determine the level of control that each team has in actual deployment. Running the system in parallel offers the advantage that if the new system encounters problems, the company can easily return to the original system.

I like your posing. you list a lot of choices and you also teach us how choose the suitable one, which is very clear and easy to follow.

Thank you for sharing , I never use Zymr before. I think it will be good according to your introduction. And I will try to use it in the future.

Yes, I agree with you. both amazon and google have high technology and good service. Their production are easy to use and safer.

I like it, too. AWS provides on-demand cloud computing platforms for individuals, companies, and governments. This technology allows users to use a mature virtual computer cluster at any time through the Internet. These costs are based on the combinations used.

The cloud I use is baidu cloud. It provides different Windows servers and users can install many Windows systems on the PC. This can also provide the PC with additional storage space through cloud services. This service is important because cloud storage can be huge and cheap. In addition, if certain applications cannot be used on other systems,…[Read more]

Good point. Vision-impaired navigation systems will have speech-based assistive or sensory technologies that make people aware of the path to the road and potential obstacles. Many of the bank’s ATM systems are also available today for people with disabilities.

I agree with you. The human-computer interaction method of the Windows operating system can help people with disabilities to better operate their computers. Therefore, these accessibility features not only improve the working efficiency of the disabled, but also help them rebuild their confidence in life.

I agree with you. With a computer interface with visual input and providing visual feedback to the user, visually impaired people may face major challenges when interacting with the computer.

I like your sharing. A person who is considered to be disabled is defined as: “A person with a disability is a person who has physical or mental impairment that severely restricts one or more major life activities; has a record of such damage; or is considered to have such a defect.”

I agree with you. By using computer technology to accomplish tasks such as reading and writing documents, communicating with others, and searching information on the Internet, students and employees with disabilities can independently handle broader activities.

It is important to increase the accessibility of people with disabilities. Regardless of whether he or she is disabled, anyone should use a computer. For example, some people lose their legs, so they cannot type words on a computer. Computers should have applications to pass what they say. These people can input these words by saying something.…[Read more]

I agree with you. If only database design experts are responsible for the design of the database, the database may not work properly because experts lack understanding of the application’s requirements.

Good point. Stakeholders and senior managers understand the requirements because the applications are designed for their use in the business. The software development team has a good understanding of software design.
