Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Question

Draw the data structure indicated in each part below for the given set of task delays.

Calculate the waiting time and Turn Around Time (TAT) for each task and the average waiting time and turn around time (Assuming there is not input/output waiting for the task) if three task enters the 'Ready' queue with task ID T₁, T2, T3 with estimated completion time 10, 5, 8 milliseconds respectively. Tasks enter the 'Ready' queue in order Т2, Т1, Т3.
In terms of their primary function, there are distinctions between "many threads" and "many processes". If it is not overly burdensome, it would be highly advantageous if you could provide further elucidation on this matter within a concise and succinct manner. I would greatly appreciate your assistance indefinitely.

Assignment/Lab 9 In this lab, your task is to develop a simple address book tool. The tool maintains contact information of people. For each person, the tool maintains name and date of birth. Contact information consists of physical address and phone number. For physical addresses, the system must be able to maintain current and previous addresses. Current/active address information should have starting date and no end date, previous addresses must have a starting date and an ending date. A person cannot have multiple active physical address. For phone number, the system must maintain active phone numbers only, no previous phone numbers. For implementation, use MySQL database system. MySQL is open source and is available for Linux as well as Windows. For software application, use Python. The tool/application must support the following functionality: 1- Search current contact information by last name, the user enters last name, the system must locate active physical address and phone…
