Explanation of Solution
Business intelligence
- Business intelligence is a set of processes that convert raw data into meaningful information.
- It is a suite of software and services to transform data into actionable intelligence and knowledge.
- It collects, stores, cleans, and makes relevant information available to managers.
- It includes databases, data warehouses, and data marts...
Explanation of Solution
Elements of a business intelligence environment
The main elements of a business intelligence environment include:
- The first element of a business intelligence environment is data from business environment which include structured and unstructured data from many different sources.
- These data are integrated and then organized so that they can be analyzed and used by human decision makers.
- The next element is business infrastructure that include powerful
database systems that capture relevant data stored in transactional databases or are integrated into an enterprise data warehouse or interrelated data marts. - The next element is business analytics tool set that consists of software tools which is used to analyze data and produce reports, then to respond to manager’s questions and at last to use key indicators of performance to track a business’s progress...
Explanation of Solution
Analytical functionalities provided by Business Intelligence systems
- Production reports are the predefined reports based on industry-specific requirements.
- Parameterized reports are the reports where users enter several parameters in a pivot table to filter data and isolate impacts of the parameters.
- Dashboards or scorecards are the visual tools for presenting performance data as defined by users...
Explanation of Solution
Predictive analysis
- Predictive analysis is the use of data, statistical
algorithms , and machine learning techniques for identifying the likelihood of future outcomes based on historical data. - Predictive analysis uses statistical analysis, data mining techniques, historical data, and assumptions about future conditions to predict future trends and behaviour patterns.
- An example of predictive analysis is an insurance company using age, gender, and driving record as predictors of driving safety.
Location analytics
- Location analytics is a visual way of interpreting and analyzing the information when used in conjunction with a geographical
information system . - It uses the location component of data, including location data from mobile phones, output from sensors or scanning devices, and data from maps to help a marketer to determine which people to target with mobile ads about nearby restaurants and stores...

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:

- Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
