I agree with you, because it is important for organizations to select the best approach to replace the systems. Business always need new technologies to make them get used to the new market. Therefore, it is important to have the better approach to deploy systems.

I agree with you, because parallel approach is the best way to use in small business. because compare with phased approach, it can reduce risks and save money . Therefore, it is reasonable for small business.

I agree with you. There are three approaches for deploying systems. Business needs to balance the risks and costs to select the approach which is suitable for them. Phased approach is the most expensive one, and direct cut is the cheapest one, but it is risky.

I agree with you, because it is important to follow these frameworks to ensure cyber security NIST is the one I usually use It provides guidelines and requirements for different security controls. It is also important to understand the relationship between different sections of NIST. It will better understand the good performance of controls.

Thanks for sharing so many could service providers. Microsoft Azure is the application I used before. It provides good could service to users. Users can select different servers for their PCs. It is good for using different applications and extend storage.

I agree with you, because SLA is important if users use third party providers’ products. It makes sure the service quality of the products. People can also measure the service level based on the standard on SLA.

The cloud I use is Windows Azure. It provides different Windows servers Users can install many Windows system on a PC. That can also provide extra storage for a PC by cloud service.

I agree with you, because it is important to help everyone access the computer regardless the type of disabled. People can install different tools to make everything easier. For example, using their voice to enter information. That improves their working efficiency.

I agree with you, because it is important for people to access to the computer no matter they are disabled or not. The people with visual problem need screen reader for them to receive the information. However, it is only public information

I agree with you, because designing a database should be a teamwork. People should collect the requirements from stakeholders in an organization. Database design expert can design the database based on the requirements, so it is important to involve many roles in a team to develop a database.

I agree with you, data design experts only deal with the technical problem in database designation. Senior managers may understand the requirements and .needs better than the experts, because they understand the direction of the business. The application should serve the business better by aligning with the direction.

I agree with you, because it is important to make the database strong. Using the strong password is a good way to protect the access authority on the database. To determine which encryption method we should use, it is important to determine the security level. Using stronger method for high security level data.

I agree with you, because each diagram has different functions. It is important for an organization to use multiple types of models and diagrams. It helps the organization describe its business process, and check for mistakes.

I agree with you, because people should use multiple methods to make sure fully description of business process. The function is limited on a diagram. Each model or diagram should play specific role in communication and description. Therefore, I like your post. I strongly agree with that you are smart.

Different diagrams have different functions to describe the business processes. If an organization only uses one kind of diagram, it will not fully display the whole process of business activities. For example, data flow diagram is used to describe how the data go though in the business process. ER diagram is used to understand the relationship…[Read more]

I agree with you, because it is difficult to determine these class diagram are all correct or not. Everyone has different thoughts in the same narrative description. It is more important to check the relationship and attributions of entities.
