Topic: Database
1. A database management system has an overall availability of 98.94%. How many minutes of downtime can be expected in a typical week (7 days), assuming uniform distribution of failures? Enter the number in minutes, rounded to the nearest whole number.
2. The data warehouse consists of a number of distinct components, including a cloud server (99.999% availability), a database management system server (99.4%), an analytics logic server (94.7%), and, of course, the network infrastructure to the cloud server, which has an availability of 99.9%. What is the overall availability of the system, expressed as a percentage with three digits of precision?
Many large organizations have had their database system hacked and customer data stolen. Your first task is to identify one company where their database was hacked. Second, how should the security for the database be different than security for the rest of the system? Does it make a difference for web-based data designs? If so, how?
Suppose you are a database administrator in your company and your company has decided to cut information technology costs by migrating its database investments from Microsoft SQL Server to MySQL. Discuss at least four steps you should take to implement your company’s requirements.

The ABC Bank stores its ATM users’ data in a database table where records are sorted based on Account Numbers as below: ATM Card # Account # PIN Name Balance (Rs.) 11122230 Ac321 999 Ali 5,000 11122231 AC431 888 Hina 3,000 11122232 AC453 777 Saad 8,000 11122233 AC534 666 Fahad 9,000 when Fahad inserts his ATM card, he enters PIN and the main screen appears which shows his Name and other details. The authentication system searches the provided ATM Card # in database table. If ATM Card # is found, the system authenticates the user by matching the input PIN with stored PIN and returns Fahad’s profile data. So, From the given array of ATM Card numbers i.e. double A={11122230, 11122231, 11122232, 11122233, …} to find Fahad’s ATM Card # double target=11122233 Write the code for your chosen search either binary or linear search technique.
