Definition of business intelligence and analytics.

Explanation of Solution
Business analytics is the methodology of using data and quantitative analysis techniques to support fact-based decision making of an organization. Business analytics is mainly used to understand the current business performance, find new business partners, optimize current operations, and predict future results of business.
Business intelligence (BI) is the approach which uses various applications, practices, and technologies to support improved decision-making of an organization. Various tasks done under the scope of BI are: extraction, transformation, integration, visualization, analysis, interpretation, and presentation of data. Data which is used by BI can come from multiple sources and can be internal and external as well.

- Outline the overall steps for configuring and securing Linux servers Consider and describe how a mixed Operating System environment will affect what you have to do to protect the company assets Describe at least three technologies that will help to protect CIA of data on Linux systemsarrow_forwardNode.js, Express, Nunjucks, MongoDB, and Mongoose There are a couple of programs similar to this assignment given in the lecture notes for the week that discusses CRUD operations. Specifically, the Admin example and the CIT301 example both have index.js code and nunjucks code similar to this assignment. You may find some of the other example programs useful as well. It would ultimately save you time if you have already studied these programs before giving this assignment a shot. Either way, hopefully you'll start early and you've kept to the schedule in terms of reading the lecture notes. You will need to create a database named travel using compass, then create a collection named trips. Use these names; your code must work with my database. The trips documents should then be imported unto the trips collection by importing the JSON file containing all the data as linked below. The file itself is named trips.json, and is available on the course website in the same folder as this…arrow_forwardusing r languagearrow_forward
