Oakmont & Partners LP has been busy building data models for a number of new clients and Monica is excited to start a new modeling effort for a local non$-$profit that provides assistance to homeless and others in need. She is keen on applying her UML and ERD modeling skills that she acquired while taking a corporate training class taught by Ars Doceo. She knows that the first step in building a conceptual data model is to conduct requirements analysis. So$,$ she sets up an interview with Kaileen Ormond, the Director of Social Pedagogy who has been with the organization for over $18$ years. To make sure she remembers what is being said, she decides to record the interview. The following is a transcription of part of that recording:

$"...$ Let me give you a scenario. So$,$ last month we took in $132$ new homeless individuals and families. After we register them and determine their eligibility to shelters, we assign them to a bed in a common dormitory room in a shelter $--$ if they are by themselves $--$ or to a small family room if they are a family of five or fewer. If they are larger, then we generally cannot help them and we refer them to social services. Once we assign them to temporary housing $($we need to record the date of the intake, as they can only stay a maximum of six months$),$ we have to see if they can qualify for any government assistance programs such as WIC. Those programs are only accessible to US Citizens or permanent residents; they are not open to asylum seekers or anyone who is undocumented or is on a non$-$immigrant visa."

Monica thinks she has enough to develop an initial data model but is reassigned to a new project where her skills in agile business analysis are needed. So$,$ you are being asked to jump in and build an initial data model. Your task is to develop a conceptual and then a logical data model for the entities and relationships within the context of the above requirements, along with a full definition of all entities. Be sure to list all your assumptions used in the construction of the data models.

Express the data model in a UML Class Diagram. Use directionality indicators on the labels $().$ Add key attributes as appropriate with the stereotype $$key$.$

To narrow and focus the scope of the model, consider only the specific requirements below. Those are the ones that the conceptual data model expressed in UML must support $--$ you may omit any other considerations as this is clearly is very large project. The likely implementation will be a small application, perhaps a web app and this data model will help inform the database design and the user interface.

$-$ track the names and key demographic information $($birthday$,$ country of birth, citizenship or visa status$)$ of all individuals registered

$-$ track immediate familial relationships, e$.$g$.,$ children $($son$,$ daughter$),$ parents, grandparents

$-$ track the shelter to which they are assigned and the type of housing $($bed or family room$),$ including address

$-$ know when they were registered and when their permit to reside in$-$country expires

$-$ track eligibility for government assistance: while you do not need to address this, how would you manage eligibility for different programs, e$.$g$.,$ a person might be eligible for one program but not for another

$-$ legal representative$($s$)$ hired by or assigned to them. Keep your model to about $6-8$ classes$/$entities$.$
