What are the problems in Mario’s system and why same problems did not occur in Danica’s system?
Expert Solution & Answer
Explanation of Solution
Given Information: There are two Auto shops similar to each other but with different information systems. Mario’s Auto shop used two file-oriented system and Danica’s Auto shop used
Explanation:
Mario’s system is divided into two file processing systems in order to manage the business. These two systems required two different files for data storage without having any link to each other. These two separate storages make that data inconsistent. That was the problem with Mario’s system. For example, there are three data items associated with Mario’s system named as
The same problem did not occur in Danica’s system because it used a database management system with two tables linked to each other. So, it would not cause any duplicity of data items and hence would not impact the quality of the data.

Develop an attack tree (Section 1.5.2) for obtaining a meal in the Student Center food court without your account being charged. Remember that an attack tree is more useful the more paths it shows to get to the goal; yours should have at least three branches (i.e., high-level approaches) under the root. Given below is Section 1.5.2.
1.5.2 Attack trees for threat modeling Attack trees are another useful threat modeling tool, especially to identify attack vectors. A tree starts with a root node at the top, labeled with an overall attack goal (e.g., enter a house). Lower nodes break out alternative ways to reach their parent’s goal (e.g., enter through a window, through a door, tunnel into the basement). Each may similarly be broken down further (e.g., open an unlocked window, break a locked window). Each internal node is the root of a subtree whose children specify ways of reaching it. Subtrees end in leaf nodes. A path connecting a leaf node to the root lists the steps (attack vector)…
This project aims to develop a sentiment analysis system for product rating. It is an e-commerce web application. The main goal of this sentiment analysis system is to
understand the hidden sentiments of customers in feedback and comments and analyzetheir product rating patterns.When registered customers use this app to view products, product features, andcomment on different products, the sentiment analysis system will analyze thecomments of various users and ranks products accordingly. The system leverages adatabase of sentiment-based keywords (including positivity or negativity weight).So, when a user comments on a particular product, the sentiment analysis systemanalyzes the keywords in the comment to find the match with the keywords stored inthe database. After analyzing the matches against the positive and negative keywordsand sentiments, the system ranks a product as good, bad, and very bad. Thus, userscan use this application to find out reviews on a product.

- Because proof-of-work incurs a lot of expenses on electricity, network, and cooling, etc. which do not seem to produce any benefit other than the maintaining the operation of the blockchain, Ethereum has proposed an alternative "mining" implementation known as "proof-of-stake" to replace its current POW design, where the amount of "ethers" held is used as "stake". Based on your understanding of POW, which of the following does NOT seem to be a necessary feature in a POS implementation? The next block producer will be randomly selected from candidates The more ethers a candidate stakes, the higher chance it will be selected as the next block producer A candidate block producer cannot use its staked ethers for some time (or forever) At any time, the candidate block producer with the most staked ether always gets selected as the next block producerarrow_forwardYou have to create a system for library management javs using oop concepts.
