What type of domain model changes can have an impact on the data in the database? Type changes and Structural changes What are the four stages of data conversion? (multiple answers are correct)

  • Deploy and convert
  • Clean up model
  • Model the conversion
  • Extend domain model Why is it a best practice to redeploy your app after cleaning up the model? You might be confronted with unexpected and/or complex sync behavior during a next deployment. What does the function reverse() do? It changes the direction in which the association is queried. What is the best naming for a self-reference where the buddy is referenced by an apprentice? Apprentice_Buddy What is the correct XPath to retrieve the goals of the buddy of an apprentice? [SoccerSquad.Goal_Player/SoccerSquad.Player/SoccerSquad.Apprentice_Buddy [reversed()] = '[%CurrentObject%]'] When localize is set to No, the date displayed in the client is based on the: UTC value Localizing a DateTime attribute has an effect on: Client representation If both the App and User time zones are set, the value of the localized DateTime attribute displayed in the client depends on: The Client time zone Jane in the Amsterdam time zone [UTC +2] selects 07/11/2020 in a date picker for a non-localized attribute. What will be the value stored in the database? 07/11/2020 12:00 AM Nick in the Amsterdam time zone [UTC +2] selects 07/11/2020 in a date picker for a non-localized attribute. What will be the date value if Nick converts it to a string in a microflow using formatDateTime? 07/11/2020 02:00 AM The Mendix Client is: Built on a combination of HTML, CSS, and JavaScript and runs in your browser. Static resources in Mendix: Include stylesheets transmitted in CSS format to the client. The Communication between the Mendix Runtime and Database Server: Includes communication between the supported database servers using JDBC. What is NOT an advantage of using the database source option versus the XPath option?

Customer, and Employee. The Customer user role is granted the Customer module role. The only access rule configured is read/write access for the Customer with the XPath [Status = Draft] applied. What would a user with the Customer user role see on a page with a data grid without any additional XPath constraints? All the requests in the Draft status. Consider the exact same situation as above. What would Admin users see? No results would be returned. Consider the same situation again. What would happen if you granted Admin users access to a page with the Request entity in Studio Pro? Studio Pro would detect an error and prevent a deployment. How does the platform use entity access XPaths to enforce security? The XPaths are added to all the relevant database retrieves. Where are entity access restrictions applied? On relevant database retrieves. Which of the following best describes how the Mendix platform applies entity access? The platform only grants the access explicitly defined in the entity access rules. In this domain model, assume that House is a specialization of Building: Admin users will be able to read the SquareFoot attribute in data views for Buildings and read and write in data views for Houses. Referring to the same domain model as was used in question #2, if we create a page with a data grid containing Houses and autogenerate a House_NewEdit page, which of the following statements is FALSE for an Admin user? Admin users will not see the SquareFoot attribute in the Edit page. Why is it more secure to add security rules on the entity level? Entity level restrictions are applied at the database level and are thus automatically applied throughout the application. For the following questions, assume there is an app with three user roles: Administrator, Teacher, and Student. Administrators are granted the ability to manage all user roles, and Teachers can manage users with the Student role. Which of the following statements is false? Administrators and teachers can create teacher accounts. Let's say you want Teachers to be able to manage accounts for Students, but only the Students who are in their class. So, you grant Teachers the ability to manage users with the Student role in the app security menu. Will this be sufficient? No, because teachers will have the ability to edit the accounts of any Student, not just their own. What is a benefit of assigning only one user role to each user? Simplicity Which operation can be used to select a specific set of rows in a table?

Selection The Set Union operation combines two lists into one that contains: one version of the objects from both lists What operation combines the data from two different entities into one table? Cartesian product What does the Projection operation do? It allows you to select attributes for all objects. Re-take Knowledge CheckNext What can you use a constrain function for? To filter on strings and dates in XPath queries. Which of the queries below can be used to filter on dates two weekso in the past? [%BeginOfCurrentDay%] - 2 * [%WeekLength%] One of your XPath queries that use the contains() function is not performing very well. What is the most likely root cause? You are using the function on a string that is set to 'unlimited'. When using the 'and' operator: The 'and' operator will give a different result based on how you write the XPath query. The not() function: Generates a slow query. Which statement best describes how you would retrieve all related objects in the most optimal way? When comparing to a related entity, it is enough to stop at the association to get the most optimal query. When should you apply an index? You should apply indexes on attributes that are used in searches when the performance of your app is not up to par. What is normalization? The removal of duplicate data from your domain model. Why would you want to do normalization? To remove duplicate data from your app so you can avoid insertion, update, and deletion anomalies. What is denormalization? The duplication of information in several entities to increase performance. What set-up items do you need to have in place before creating your REST methods? Choose one of the below. An entity with attributes, a Published REST service and a resource in the Published REST service What does a GET method do? Choose one of the below Allows information sharing between my app and other apps, where the other system can determine when to retrieve that shared information.

Warning, you can still continue but someone should look into why the REST call is failing and whether further action is needed. Which of the following is a valid Mendix token? CurrentUser You are creating a microflow where you have a Change Object activity. The change is dependent on a lot of checks and decisions (but, whichever choice, the change always happens). What is the best way to model this microflow? Use Decisions, but place them in a sub-microflow to determine what the new value should be, and then use the return value of that sub-microflow in the Change Object activity. You need to determine what day of the week it is. What is the easiest way to do this? Use the formatDateTime function to achieve this. What is the best approach to retrieve an object over association, while also checking whether the association exists? Use a decision to first check whether the association exists. If it does, retrieve the associated object. Which of the following statements about lists is true? A list can have, among others, the following origins: a retrieve action, the creation of a new list, and the result of an input parameter. You have to determine how many customers are in the database and find that there are at least a couple thousand. How do you handle this? Retrieve all the customers at once and use an aggregate list activity to count them. Because this is an optimized query on the database, it will be very light and safe to use, even for big lists. What does the List Operation tail do? It grabs all elements in the list except the first element. When would you typically use a List Operation?

  • To avoid complex XPaths.
  • When you are working with objects that only exist in memory.
  • When creating report data to view in chart widgets. You've created a microflow that contains a loop. This loop uses the same logic as a microflow you have already built, so you decide to call this microflow as a sub-microflow inside the loop so that you can reuse the functionality. What do you check before doing this?
  • If there are retrieve activities in the sub-microflow for data you already have available in the main microflow, check whether it can be passed along as an input parameter instead.
  • You make sure that there are no commits in the sub-microflow, since it is not good for your application to commit inside of a loop.
  • If the sub-microflow uses a return value, you check whether it is really needed. Your application contains a microflow that calls three sub-microflows. Each of these sub- microflows does a retrieve from the database on the same entity. Should you change this?

Yes, you should do the retrieve in the main microflow and then pass it along to the three sub-microflows as an input parameter. Which statement about rules is true? A rule can only be called from within a decision. What is a good reason to use a sub microflow?

  • To use it as a 'get or create' microflow.
  • To reuse the same bit of logic in multiple microflows.
  • To increase readability of large microflows. To which of the following errors types does the built-in consistency checker in the Modeler alert you? Technical issues in your model. Which of the following statements is true? The output of log nodes can be used to isolate problems and place breakpoints in a smarter way. When will this microflow break? Each time the breakpoint is passed. Can you pause a microflow only when certain conditions are met? Yes, by adding a conditional breakpoint. When you're creating a new microflow and you have to create the logic, what is the recommended place to start? At the end of the microflow Why are we creating sub-microflows? To be able to reuse the functionality and have a microflow with dedicated functionality What happens when Mendix is not able to finish the transaction successfully and there is no Error Handling implemented? The transaction is stopped and Mendix will show an error message in the user interface. You need to create error handling for JAVA actions because: Mendix is not able to catch errors that occur in a JAVA action by default. Error handling can occur in microflows that are triggered by: Both, a user and the system It is necessary to create a log message and a user message because: The log message will not appear in the frontend. Which of the following options needs to be selected to fix an error indicating that the there is no object type selected for the Courseplanning import template? Select the missing object in the properties of the template. After an object has been connected to a template, what you must ensure to do before saving this template? Connecting matching attributes.

Which is not a way we can create a typographic hierarchy?

  • Color
  • Weight
  • Size
  • Images Images Which of the following is NOT a benefit of good typography hierarchy?
  • Ease of navigation
  • Keeps cost low
  • Improves usability
  • Enhances readability Keeps cost low If you wanted to provide feedback to your users that they had entered their date of birth in the wrong format, which visual cue would be best suitable? We're sorry, but you need to enter your date of birth in mm/dd/yyyy format Why should you use familiar UI patterns? To help your users feel more at home If you wanted your users to enter a multi-lined delivery note to go with their order, what widget would you use? Textarea Which one of the following is a way to help make your pages smarter? Conditional visibility What does the helper class ".hidden-xs" do? Hides content on the phone. What are the three triggers options of widget events? On-enter, on-change and on-leave By using conditional editability you can change elements to be either? Editable or read-only If I had a device with a screen width of 800px which column class prefix would be used? col-sm-* The pre-processor Sass helps with what? Maintaining your CSS stylesheets Which of the following are AtlasUI components? Page Templates, Navigation Layouts and Building Blocks What do you need to take into account when using Sass? You need a compilation tool Which of the following does the Mendix AtlasUI Framework NOT enable?

Documentation for your microflows To start customizing your Mendix application you should: Start with using and customizing Mendix AtlasUI Submit Answers
