A ratio table is more like a pattern, where a data table has graphs.

standard normal is for a lot of data, a t distribution is more appropriate for smaller samples, extrapolating to a larger set.
A graph is similar to a data table in that they both present the data. A difference is that the graph is more of a visual representation. Often, trends in the data are easy to recognize in the visual representation of the graph.
A graph does one thing that a data table doesn't do, which is allow a visual representation of the data to be created. This would allow you to see, for example, that a series of data points rises in a straight line far more easily than a bunch of numbers in a table would. Additionally, graphs are good for comparing data, say volumes or masses for example, so that you can see how one value compares to another. All in all, it allows you to see all the data points at once, compared to each other, so that you can draw conclusions about the data as a whole.
between two or more varibles

projecting: manipulating data to eliminate columns in a table. Joining: manipulating data to combine two or more tables.
A DBMS stores data in a table where the entries are filed under a specific category and are properly indexed. This allowed programmers to have a lot more structure when saving or retrieving data. A relational database contains data in more than one table. Each table contains a database that is then linked to other tables with respect to their relationships.

A graph can be more useful for making presentations because it is more visual, and it can be easier to recognize a pattern in a graph for the same reason. However, a graph doesn't have any more data than a table with the same data.

it is easier to read and is more recognizable and it is easier to keep organized
Though a table contains the data, it needs to be studied carefully. A graph, on the other hand, is an easier way to graphically show the same data, but in a more visually way.
No it can only have one
In SQL, a view is a virtual table based on the result set of a SQL statement, which can be queried like a table. An index is a data structure that improves the speed of data retrieval by providing quick access to the rows in a table based on the indexed column(s). Views are used to simplify query complexity, while indexes are used to optimize data retrieval performance.
