Within a data model you need to specify the association between entities. In XSD terminology this is represented as follows <xs:element type="itemsType" name="items"/>. However, sometimes we see a different notation that is not working when importing an XSD in eMagiz. This notation is <xs:group ref="status_group" />. To get this in you need to rewrite the association in your XSD a bit to reflect the first notation and mention that the assocation is optional (minOccurs="0"). 55 55 56 -=== 3.4 C ross referencebetweenentitiesthatcould lead to aninfiniteloopare not accepted ===60 +=== 3.4 Choice statements cannot be represented in the data model === 57 57 58 - Insomeasesweseedefinitionsinwhichentitieskeepreferecingeach other.Thiscouldcause aninfinitelooptooccur when trying tobuilduphecorrectstructure ofyour system message.Therefore wedoan initialcheck whenimportingyourfileto safeguardourselvesagainstcreatinginfiniteloops in ourportalthatwillin the endbreakthe eMagizportal.62 +As specified before in earlier microlearnings, eMagiz defines the expected structure with the help of data models. Within a data model you need to specify the association between entities and order within these entities. In XSD terminology this is represented as follows <xs:complexType><xs:element name="employee" type="employee"/><xs:element name="member" type="member"/></xs:complexType>. However, sometimes we see that a choice is offered in the XSD. This notation means that you can supply A or B. This notation is <xs:complexType><xs:choice><xs:element name="employee" type="employee"/><xs:element name="member" type="member"/></xs:choice></xs:complexType>. To get this in you need to remove the reference to the <xs:choice> and the </xs:choice> lines in your XSD and make each element within the choice optional (minOccurs="0"). 59 59 60 -== 4.Assignment ==64 +=== 3.5 Iterations (maxOccurs) over a threshold of 50 are not accepted === 61 61 62 -Make sure that at least one of the attributes within one of your data models is set to Confidential 63 -This assignment can be completed within the Design phase of your (Academy) project that you have created/used in the previous assignment. 66 +To prevent weird results when it comes to the creation of data models we do not accept maxOccurs above 50. To succesfully import your definition you should change the maxOccurs setting to unbounded. This way eMagiz will succesfully import the definition.

This could cause an infinite loop to occur when trying to build up the correct structure of your system message. Therefore we do an initial check when importing your file to safeguard ourselves against creating infinite loops in our portal that will in the end break the eMagiz portal. 71 + 72 +== 4.
