CMIS 102 University of Maryland Global Campus Coding Project
The second assignment involves writing a Python program to compute the price of a theater ticket. Your program should prompt the user for the patron's age and whether the movie is 3D. Children and seniors should receive a discounted price. There should be a surcharge for movies that are 3D. You should decide on the age cutoffs for children and seniors and the prices for the three different age groups. You should also decide on the amount of the surcharge for 3D movies. Your program should output the ticket price for the movie ticket based on the age entered and whether the movie is in 3D.Your program should include the pseudocode used for your design in the comments. Document the values you chose for the age cutoffs for children and seniors, the prices for the three different age groups and the surcharge for 3D movies in your comments as well.You are to submit your Python program as a file (.py) file. In addition, you are also to submit a test report in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.

ITCO 620 AIU Week 1 Developing Applications Project Paper
Assignment DescriptionDeveloping applications requires much forethought and planning. This project will guide you through the various steps of designing a program that meets a set of requirements. When requirements are understood, software development techniques and tools can be applied to design the objects needed by the program. Once the design has been determined, program logic can be defined. Finally, writing source code can begin.For this assignment, you will need to refer to a set of requirements, design the program, and then create the code.Application RequirementsYou have been requested to develop a Java application for a large company that provides members and the general public an online product catalog for ordering items like books, DVDs, clothes, household products, and so forth. There are several levels of users, including public (user has not registered), level 1 member, level 2 member, and level 3 member. The level 1 member pays a small monthly subscription fee. Level 2 members are associated with a small business who pays an annual fee covering less than 100 members. Level 3 members are employees of large corporations (more than 100 members) who subscribe annually. As the level increases, so does the discount. The following list highlights these requirements.The requirements for the application are as follows:The application will act as an online ordering system.The company accepts orders online and ships those items to the customer address.Customers must create a line of credit prior to placing an order.Customers view products from the catalog of items.Customers place orders.The administrator updates account information on behalf of members.Administrators add, delete, and modify items in the catalog.The application is able to run under most operating systems, including UNIX and Windows, and has a modern graphical user interface.The application is designed for future growth.Part 1 (55 points)Review the requirements and, using Visio, develop your design by creating use case diagrams, a class diagram, and a sequence diagram. Templates can be found in Visio by accessing the UML System template. There is a use case shape to help you create your use case diagrams. There is a UML sequence shape. Under "More Shapes," you will find an entity relationship shape for your class diagram.Click here to refer to a Visio tutorial to learn Visio basics.Use case diagrams are used to summarize the relationships between use cases, actors, and systems.Use Case 1: Create AccountUse Case 2: Place OrderUse Case 3: Add Product to CatalogUse Case 4: Update Account InformationSequence diagram that illustrates the various object interactions in their proper sequential order.Class diagrams depict the objects and information structures used by the application. The definition of a class is independent of the application itself. Classes describe the objects managed by the application but are independently defined. Be sure to show relationships between class objects, attributes, data types, and methods in your diagram.Class 1: AccountClass 2: Account LevelClass 3: AddressClass 4: ProductsClass 5: OrderClass 6: Line ItemOnce you have completed your diagrams, copy them into a Word document that will serve as your application design document. Include explanations for each diagram in your design document.Part 2 (25 points)Create pseudocode that describes the necessary flow of your program with respect to both creating a user account and placing an order. This information should be included in your application design document. This information should be included in your application design document.Part 3 (45 points)Explain your steps regarding taking the business requirements and developing your application design. Provide details as to the importance of following these important steps prior to coding the application. Describe the advantages and disadvantages to this process. Discuss how this process relates to the software development life cycle.Parts 1, 2, & 3 are all included in the application design document.Please submit your assignment.For assistance with your assignment, please use your text, Web resources, and all course materials.Grading CriteriaProject CriteriaExceeds: 90%–100%Very Good: 80%–89%Meets: 70%–79%Needs Improvement: Below 70%Content(65%)Response covers all topics indicated in the assignment and adds additional content.Response covers most topics indicated in the assignment.Response covers many of the topics indicated in the assignment.Response covers none to some of the topics indicated in the assignment.Effective Communication(20%)Demonstrates outstanding or exemplary application of written, visual, or oral skills.

Query Processing and Sorting
Query Processing and SortingThis week looks at Query Processing and the concepts of pipelining and materialisation. Through these exercises, we hope you come away with an appreciate and understanding of why databases use pipelining and why it is more efficient that materialisation in most cases.Extra Details for the Scaffold CodeThe query engine is what converts the text "SELECT name FROM students", into the commands the database can understand, e.g. load table students, project over the name of each student, print out the results. Each of the filters you add in filterWhere, are a way of chaining iterators. This is essentially how this Database pipelines its data. Reading one row at a time, it checks if a condition is true. If it is the row is returned, otherwise the next row is looked at. filterWheretakes an iterator and a where clause as its arguments. Using this, it determines what comparison is needed (e.g. greater than, less than) and applies it to the iterator and returns it (pipelining!!) execute runs a query, and pieces all of the different stages of the pipeline together. e.g. applying a projection or a filter to the iterator The limit operator does exactly what you expect. Taking a number X, it will return the first X rows from an iterator before it will stop.EasyFor this task, you are expected to:Finish the implementation of the WHERE clause in our query parser. Have a look at QueryEngine, specifically the filterWhere and execute methodsImplement the LIMIT operator that can be found in the execution package.Pass the LimitTest and QueryEngineTest unit testsWhat you are doing here, is actually implementing the WHERE and LIMIT clauses in the database. We strongly encourage to try running the Main.java file and entering in the commands to try out each of these keywords once you have implemented them.MediumFor this task, you are expected to:Implement the Easy taskImplement the InMemoryOrderBy class in the sort package. This asks you to materialise the rows and sort them in memoryPass the InMemoryOrderByTest unit testsThis involves modifying InMemoryOrderBy so you are sorting the rows in memory, and filling out the methods for the AccessIterator so the database can access this result one row at a time. Hint: Column Comparator may be usefulHardFor this task, you are expected to:Implement the Easy taskImplement the ExternalMergeOrderBy in the sort package. This asks you to implement the External Merge Sort algorithm covered in the lecturesPass the ExternalMergeOrderByTest unit testsThis involves modifying ExternalMergeOrderBy so you are sorting the rows as per the External Merge Sort algorithm. Each method in the class is well documented so it's purpose should appear clear to you. If you are still unsure what is going on don't hesitate to post a question to the discussion forum. Hint: Column Comparator may be usefulNote: If you want to test ExternalMergeOrderBy in your command line query parser, you will need to change the line in QueryEngine from using the InMemoryOrderBy, to ExternalMemoryOrderBy class appropriately. You do not need to do that to pass the testsThis time hopefully you all should have a bit more fun with the code since you can execute queries and see the result. If you run the Main method, it will prompt you for input and an example query you can run would be SELECT name, age FROM students. As you implement, LIMIT, ORDER BY and WHERE you can actually see the results in the queries that you do.Unlimited private and public hosted repositories. Free for small teams!20 hours agoATTACHMENTS
