Programming - Test the system
- Implementation of system
- Maintenance of system.

Information system prototyping:
It is an alternative model for building information system. It has a prototype which represents the requirements of the user.
Benefits of information system prototyping:
- The benefit of information system prototyping is exactly matches to the customer requirements and these model is mainly used to enhance the bigger projects.
- It is useful for routine problems and this information system is very structured and well-understood.
- It reduces the implementation cost of the project.

- It is not appropriate for massive amounts of data...
Explanation of Solution
End-user development:
End-user development of information system is refers the programmers and system analysts. It gives the direct control to the project. By using the end-user development model, the project is rapidly developed with standard programming tools.
Advantages of end-user development:
- It takes minimal time to finish the software and the customer requirements in project.
- The tools are used by professional programmers in productivity levels...

Application software packages and cloud software services (SaaS):
- The software packages is common tool for all business organizations for its daily process like payroll, inventory control, etc. Many organizations use cloud services for its higher security.
- SaaS is one of the cloud software services in cloud computing. In SaaS, the software is deployed from a cloud provider; internet is used to deliver the service and the subscribers access the service through the browser.
Advantages:
- Using application software packages, the organization got a solution in quick and easy way...
Explanation of Solution
Outsourcing:
Outsourcing means taking a company for contract to complete the specific task of some other company project using the in-house employees.
Advantages of outsourcing:
- Company takes specialized skills.
- Provides labor flexibility.
- Cost effective.
Drawbacks of outsourcing:
- Increases the confidence on third parties.
- Lacking the knowledge of in-house for complex business operations.
Favorable circumstances for the outsourcing strategy are as given below:
Lack in experience:
- Whenever there are less experienced professionals in any organization, then for a new system design, the organization always prefer the outsourcing strategy.
- Hence, the product is designed by the other firm.
Inadequate resources:
- If an organization does not have adequate resources, then outsourcing of the project must be done.
- Organization can hire different vendors, developers, or suppliers to meet their needs...

Explanation of developing e-business applications:
- Developing e-business application is a needed one for every business for its development. RAD is the technology of process for developing systems in short period of time...
Explanation of Solution
Development of the mobile application:
- Smart phone tend to become more important part in every person’s day to day life routine.
- Every process required to be made in a smart manner and it is considered to be more important in case of the business process.
- Every customer requires process that is made should be effective a...

- Please include comments and docs comments on the program. The two other classes are Attraction and Entertainment.arrow_forwardObject-Oriented Programming In this separate files. ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo!

[20 pts] Student A B will enjoy his picnic on sunny days that have no ants. He will also enjoy his picnic any day he sees a hummingbird, as well as on days where there are ants and ladybugs. a. Write a Boolean equation for his enjoyment (E) in terms of sun (S), ants (A), hummingbirds (H), and ladybugs (L). b. Implement in Logisim, the logic circuit of E function. Use the Circuit Analysis tool in Logisim to view the expression, include an image of the expression generated by Logisim in your report. 3.[20 pts] Find the minimum equivalent circuit for the one shown below (show your work): DAB C…arrow_forward

DeShawn wants to determine the number of webinars the company can hold on Tuesdays and Thursdays to make the highest weekly profit without interfering with consultations, which are also scheduled for Tuesdays and Thursdays and use the same resources. Use Solver to find this information as follows: a. Use Total weekly profit as the objective cell in the Solver model, with the goal of determining the maximum value for that cell. b. Use the number of Tuesday and Thursday sessions for the five programs as the changing variable cells. c. Determine and enter the constraints based on the information provided in Table 3. d. Use Simplex LP as the solving method to find a global optimal solution. e. Save the Solver model below the Maximum weekly profit model label. f. Solve the model, keeping the Solver solution.

For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)? When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene. Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency.
