What are the advantage of using fixed length fields instead of variable length fields in a database?

A fixed length field is one which contains a set number of characters.With fixed length fields, the fields may need to be padded out to the right length, eg with characters.eg If a Surname field is set at 10 characters then the name SIMPSON would need 3 s added on to the end of it.Advantage - Every record is the same size, so it is possible for the computer to calculate exactly where each record starts in the file and therefore it is quicker for the computer to find a particular record.


What is variable field length?

The amount of data stored in such fields can vary in length. Usually you do specify a maxmimum length so that databases can optimize how data is stored and accessed.


What is the length of a sports field?

Define fixed length fields?

Fixed length fields are columns in a database table that always use a set amount of space for each row of data in the table. A fixed length field of 50 characters will always consume 50 characters for that field, regardless of how long the actual data in that field requires. Fixed length fields typically use more storage resources than variable length fields, but they are a bit faster for the processor to work with, since the length only needs to be determined once. Fixed length fields are appropriate for data where the length is constant. Some examples of fields that are good candidates for fixed length fields include Social Security Numbers, fixed length postal codes/ZIP Codes and telephone numbers (provided international data is unexpected.) Data that varies in length should be stored in a variable length field, as it will take less physical storage space and will not need to be truncated to remove extra spaces.


What is a variable length system?

It means that the length of something can vary, that it is not always the same length. The expression "variable length" may be used in different context, so I don't know what the item of variable length is that you heard or read about.It means that the length of something can vary, that it is not always the same length.

Is forearm length a discrete variable?

No, it is a continuous variable.


What is the independent variable?

Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.

How do you plot concentration against length in a graph?

It depends on which variable is independent, and which one is dependent (its value is determined by a function of the independent variable). So suppose that concentration is a function of an arbitrary length (the length is what determines concentration). The independent variable (length) is put on the horizontal axis, and the dependent variable (concentration) is put on the vertical axis.
