Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models which includes;
1. Platform as a Service (PaaS).
2. Infrastructure as a Service (IaaS).
3. Software as a Service (SaaS).
Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.
Hence, Software as a Service (SaaS) supports multiple users and provides a shared data model through multi-tenancy model. A multi-tenancy model can be defined as a software architecture that provides services to multiple end users through an instance of the software application running on a server. Thus, in SaaS multiple end users can share the software application, a single database, and each user being logically separated from one another.
Three visual data analysis tools. are :
-
Charts
- Dashboards
- Graphs
Explanation:
- Visual Analytics is the science of analytical reasoning supported by interactive visual interfaces. Today, data is produced at an incredible rate and the ability to collect and store the data is increasing at a faster rate than the ability to analyze it.
- Tableau is a great option for those who need to create maps in addition to other types of charts. Tableau Public is also a great option for anyone who wants to create public-facing visualizations
- Dashboards are where the majority of data visualization takes place. They create charts and graphs for specific data, constantly updating with the latest real-time information to keep you informed. Dashboards are great for at-a-glance or ad-hoc analysis when you just need to quickly check your data.
- Data visualization is another form of visual art that grabs our interest and keeps our eyes on the message. When we see a chart, we quickly see trends and outliers.
One large factor of social media affecting social movements is the ways a popular individual can get sponsored and people will believe whatever it is because it is a celebrity. To elaborate, let's say Albert Einstein found a way to solve an unsolved paradox, but is fake, and was also on social media, most people will believe it because he is popular. I hope that makes sense.
