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.

Consider the bitmap representation of the free-space map, where for eachblock in the file, two bits are maintained in the bitmap. If the block is between0 and 30 percent full the bits are 00, between 30 and 60 percent the bits are01, between 60 and 90 percent the bits are 10, and above 90 percent the bitsare 11. Such bitmaps can be kept in memory even for quite large files. Outline the benefit of the bitmap technique over free lists in searching for free space and in updating free space information.
You're not sure what the data represents, but you've been told it uses a dual layer obfuscation as follows: Hex with "\x" delimiter Base64 with standard alphabet After you de-obfuscate the given Hex dats, what information do you find? Do some research. What have you found? NOTE: DO NOT BROWSE THESE! Hint: focus on the strings following "/". Essentially, this practical has two stages: 1. De-obfuscate the Hex and give the output. 2. Research the nature of what you found and identify it.

1. Create your own BitArray class that has a conversion function that converts Boolean values to bit values (without deriving from the BitArray class). Use a BitArray as the class's primary data structure, but create your own implementations of the other methods, as a hint.
Write a program in MIPS Write a program that first initialize a 4 by 4 table with random integer values. Then read the diagonal elements and print each of the diagonal cells. Finally display the sum of all diagonal cells.
A ring buffer, often known as a circular queue, is a fixed-size N FIFO data structure. It can be used to transport data between asynchronous processes or to store log files. When the buffer is empty, the consumer must wait for data to be deposited; when the buffer is full, the producer must wait for data to be deposited. Create a RingBuffer API as well as an implementation that uses an array representation (with circular wrap-around).
