A complete BU 455 Unit 4 batch and streaming design: each workload sorted by how soon its answer is needed, both paths designed, and their meeting point specified. Searches like "bu 455 unit 4 assignment example", "bu455 unit 4 sample" and "bu 455 unit 4 example" land here.
What a finished BU 455 Unit 4 batch and streaming design looks like
The deliverable is a design document built around a table. The table gives each workload in the case a row, and records who consumes the output, how soon after the event they need it, what actually happens if the answer arrives an hour late, and how a record would be corrected if it turned out wrong. The decisions then fall out of those columns instead of being announced. A batch path is designed with its interval, its ordering and its restart behavior written down, and a continuous path with its treatment of records that arrive twice or out of sequence. A closing section identifies the figures both paths produce and states what reconciles them when the two disagree.
How a BU 455 Unit 4 example is structured
The cost of lateness is recorded before any path is chosen, because urgency a stakeholder asserts and urgency the case can demonstrate are different things, and most workloads survive an hour late without anyone noticing. Workloads are separated rather than handled as one system, since a case almost never needs everything continuously and designing as though it did is how a recommendation becomes unaffordable. Correction behavior is captured in the same table as timing, as a figure nobody can restate afterward carries a constraint that timing alone never shows. The batch path is designed first, because it is the easier thing to get right and the continuous path frequently ends up feeding it anyway. Reconciliation closes the document: two paths computing over the same events will disagree eventually, and a design with nothing to say about that is unfinished.
Lateness costed before any path
Each row records what happens when the answer arrives an hour late, since asserted urgency and demonstrated urgency are rarely the same thing.
Workloads separated, never bundled together
The case is split row by row, because almost no organization needs every figure continuously and designing as though it did runs up the bill.
Correction behavior captured beside timing
Whether a figure can be restated later sits in the same table as how quickly it is wanted, since the two constrain different things.
The batch path designed first
Interval, ordering and restart behavior are settled on the simpler path, which the continuous one commonly turns out to feed anyway.
Repeated and out-of-sequence records addressed
The continuous design says what happens when an event arrives twice or late, because both are ordinary occurrences rather than exceptional ones.
A reconciliation section at the close
Wherever both paths produce the same figure, the document states what happens when they disagree, since sooner or later they will.
Where marks go in BU 455 Unit 4
This design loses points by treating everything as urgent. A document routing every workload down a continuous path, with no column showing what lateness would cost, has skipped the analysis and jumped to the expensive answer. Timing requirements written as adjectives sort nothing. Continuous designs silent on the record that arrives twice or out of sequence have described the easy case only. Batch designs with no restart behavior leave the first failed run undefined, which is where these things break. Throughput claims presented as current fact are unsafe in a field that revises them between releases, and a dated citation protects the argument. Documents where both paths compute one figure and nothing reconciles them have designed a disagreement in. Event rates measured inside your employer's systems are not yours to publish.

BU 455 Unit 4 questions, answered
The case says the business wants everything in real time. Then what?
Record the request and test it against consequence, which is precisely what this unit asks for. Wanting a figure immediately is not the same as being unable to act on it an hour later, and the column between those two is what actually happens in the meantime. Where the case genuinely supports it, design for it and state what the continuous path costs against the alternative.
Does the design have to include both paths?
Not necessarily, and concluding that one path serves the entire case is a legitimate result when the table supports it. What earns the criterion is visible sorting work: every workload examined against timing and correction, and the ones that could have justified a second path named rather than passed over. A single-path design with no evidence of that examination reads as a default.
Could I model this on the pipeline my company runs?
Design the case instead. Event rates, the intervals your jobs run on and what breaks when one of them fails are operating details of a system the organization depends on, and a submitted document is outside anyone's control once uploaded. Build on the assignment scenario. What you have watched fail at three in the morning will still shape which failures you think to design around.
