On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound. -think you are in a different place
Analytics
is an encompassing and multidimensional field that uses mathematics, statistics, data mining, visualizations, predictive modeling and machine learning techniques to find meaningful patterns and knowledge in recorded data.
Union
is another method for combining two or more tables by appending rows of data from one table to another. Ideally, the tables that you union have the same number of fields, and those fields have matching names and data types.
Right join
is asking for all the rows from the table displayed or listed on the right and, if there's a match in the table on the left , match it up. When a value in the right table doesn't have a corresponding match in the left table, you see a null value in the data grid.
Full outer join
is asking for every row from the table on the left and every row from the table on the right. If they have matching values, the computer matches them up. If they don't have matching values, the computer will still display each row, but show nulls where they don't match.

You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.
Augmented reality
is the integration of digital information with the user's environment in real time. Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it. -ex google glass
data mining
is the process of sorting through large data sets to identify patterns and establish relationships to solve problems through data analysis. Data mining tools allow enterprises to predict future trends.
Left join
join is asking for all the rows from the table displayed or listed on the left and, if there's a match in the table on the right match it up. When a value in the left table doesn't have a corresponding match in the right table, you see a null value in the output.
Inner join
join matches up records between two tables based on designated values. The result set that you get contains the rows from the table on the left that match the table on the right. If there are rows in either table that don't match, they aren't returned in the result set.
