What a finished BU 453 Unit 1 requirements to entities exercise looks like
The deliverable is a table of candidates with a column nobody expects. Each row names something the business needs to keep track of, lists the facts recorded about it, states what would identify one of them uniquely, and quotes or cites the phrase in the scenario that put it there. A second table holds the nouns that were considered and rejected, with a reason beside each: a report is output rather than a thing to store, a status is a value rather than an entity, a department mentioned once may be a label rather than something with its own facts. An assumptions list follows, recording every place the narrative was ambiguous and which reading was taken. Nothing is drawn yet, and no relationship is described, because both belong to the next unit.
How a BU 453 Unit 1 example is structured
Every candidate carries its source phrase because the exercise is a reading of the scenario, and an entity list assembled from general knowledge about how businesses work will not match the case the rubric was written against. Rejections are recorded rather than left out, since the interesting decisions are the nouns that looked like entities and were not, and an exercise showing only survivors hides all of its reasoning. Identifiers are chosen at this stage so that a thing with no way of being told apart is caught while the model is still cheap to change. Attributes are stated as single facts, because a field holding two things is the defect the next several units spend their time undoing. Assumptions close the document, as a narrative written by a person always leaves something open and a reader needs to know which way it was read.
Each entity traced to its sentence
The scenario phrase that produced a candidate sits beside it, since a list built from general business knowledge will not match this case.
Rejected nouns recorded with reasons
Words that looked like entities and were not appear in their own table, because those decisions are where the reasoning shows.
An identifier chosen for every entity
Anything the business cannot tell one instance of from another is caught here, while the model still costs nothing to change.
One fact per attribute
An attribute holding two things at once is split now, since that single defect is what the following units spend their effort undoing.
Ambiguities written down as assumptions
Every place the narrative could be read two ways is listed with the reading taken, because the marker cannot see your reasoning otherwise.
Where marks go in BU 453 Unit 1
The usual failure is a list of every noun in the scenario. Turning report, total, manager and status into entities produces a model that cannot be built, and it shows a reader that the narrative was scanned rather than read. Entities with no identifier leave the next unit with nothing to relate. Attributes that bundle two facts into one field, such as a name and a location together, guarantee trouble the moment anything is queried. Candidates accepted with no source phrase cannot be checked against the case. Exercises that draw a diagram anyway have started the next unit before finishing this one. Ambiguities resolved silently look like carelessness, since a marker reading the same scenario will have noticed them. Requirements taken from an employer's own systems are that employer's business rules.

The instructions and rubric from your BU 453 classroom are the starting point, along with the scenario the assignment supplies. The custom example lists candidates with their source phrases, records what was rejected and why, fixes an identifier for each entity, keeps attributes to a single fact and closes on stated assumptions.

BU 453 Unit 1 questions, answered
How do I tell an entity from an attribute?
Ask whether the thing has facts of its own that the business records. A color usually does not and belongs to whatever it describes; a supplier usually does, since somebody keeps an address and a contact for it. Where the scenario records only one fact about something today but plainly treats it as a thing, say so in the assumptions and choose deliberately rather than by feel.
What if the scenario leaves something out?
Assume, record the assumption and move on. A narrative of a few paragraphs cannot describe a whole business, and every model built from one rests on things the writer did not say. What separates a strong submission is that the gaps are listed where a marker can find them, with the reading you chose, rather than filled in quietly and discovered later when the schema will not hold.
Could I model my own workplace instead of the given scenario?
Only if the instructions invite it, and even then keep the organization unnamed and the details invented. Requirements gathered on the job describe how a real company runs, which is competitive information whether or not anybody labeled it that way. The supplied scenario exists so the graded artifact can be shared, kept and compared without any of that hanging over it.
