How can you make a table of values for the expression 4n plus 3?
Select a set of values for n. Usually, n takes the values 1, 2, 3, 4, ... In each case, calculate 4 times the value of n and then add 3. Each n and the associated value for 4n+3 form a row/column of the table.
What is the proper way to set up a data table?
For Excel, it depends on the kind of table you are setting up. You can have a one-input or a two-input table. For a one input you put a set of figures either in a column or a row. You then need a formula for the table to work off. That is put at the top of the empty column that you want data to go into, or the start of the empty row that you want to put data into. Select your formula, the row/column of figures and the blank row/column where data is going to go. You then start the Data Table option. You will be asked for a row input and a column input. If you have your figures in a column, then you put a cell reference into the column input that is in the formula. If they are in a row, then you use the row input. The data fills in then. For a two-input, you will have data in a row and data in a column and a formula in the cell which is above the column and at the start of the row, or the top left cell in the table. You select the row and column with the existing data and the area you want the data to go into. Pick your row and colmn inputs based on the cells in the main formula. Your table will then fill in.
What does transpose mean in computer?
It means to change the layout of data, in terms of its direction. So if data is in a row, transposing it would put into a column. Transposing data in a column will put it into a row. A full table of data can be transposed, not just one row or one column.
What is a database record?
A database record is a row of data in a database table consisting of a single value from each column of data in the table. The data in the columns in a table are all of the same type of data, whereas the rows represent a given instance. Example Table: ========================================================== Column Names: ID FirstName LastName BirthDate ========================================================== 1 George Gray 1/6/1960 2 Thomas Green 2/29/2000 3 Cynthia Black 5/30/1976 ========================================================== For the given table above, an example of a column of data would be FirstName. All the values in that column are first names. An example record (or row) would be the record with ID = 2 which represents the record for Thomas Green and contains each field from that row. Properly designed relational databases use "primary keys" to uniquely identify records in a database. The value (or values) that compose the key must uniquely identify the entire row and only that entire row in that table. That primary key can then appear in another table to represent a relationship between that table and another table. In the example above, the ID column would serve as the primary key for the table.

What are Column Labels in the areas of a Pivot Table?
Each pivot table is different, so it depends on how you have it laid out and what data is in it. Pivot tables are very flexible, so you can switch around the data and column headings could become row headings and the data can change. Column headings will indicate what the data in a particular column in the pivot table is.
What is the definition column row cell?
In a table, a column is a vertical arrangement of data, a row is a horizontal arrangement, and a cell is formed at the intersection of a column and a row and holds a specific piece of data. Together, columns, rows, and cells organize and display information in a structured format.
What are the distinctive features of a Relational Data Base?
