Suppose that your company has decided to change the architecture of the software your team works on. The goal is to try to support more concurrent users.

What are two risks you might worry about? (This should be about the project itself -- assume there is still a market for your software and so on.)
Give one suggestion for addressing each risk.

Expert Solution

The possible risks and the its solution are:

1. Data Integrity: When two users try to modify a data in the database at the same time or when one user is editing information whilst others read the original data can affect the integrity of system's data. Data integerity can be ensured by introducing concurrency control system. A concurrency control system provides safe access to shared information, removing the risk of collisions that cause data integrity problems or data loss. This is achieved by either preventative locking, where access to data being edited by another user is limited or removed, or by the detection of collisions, where problematic changes are disallowed.

2. Impact in system performance due to increased traffic on the application: When a number of users tries to concurrently access the application, there can be issues in in terms of responsiveness and stability of the software under a particular workload resulting the system to crash or work at slow pace. This can be resolved by doing performance testing on the system before deploying to validate the resposiveness of the system during high traffic. It is done to identify bottlenecks in the system. Load testing is the simplest performance testing.

Suppose that we've decided to test Clara, who works at the Psychic Center, to see if she really has psychic abilities. While talking to her on the phone, we'll thoroughly shuffle a standard deck of 52 cards (which is made up of 13 hearts, 13 spades, 13 diamonds, and 13 clubs) and draw one card at random. We'll ask Clara to name the suit (heart, spade, diamond, or club) of the card we drew. After getting her guess, we'll return...

Suppose that a software development team released an update to one of their mobile applications after receiving complaints about the previous version from 9.4% of their customers. A few weeks after the update was released, the development team wanted to know if fewer customers had complaints. The team selected a random sample of 325 customers and found that 21 of them submitted complaints about the application after the update was released. The team wants to use a one‑sample z ‑test for...
