the rang ( of the rang ) the difference between the maximum and minimum values in a data set.
The difference between varchar and nvarchardatatypes is that Nvarchar stores UNICODE data. If you have requirements to store UNICODE or multilingual data, nvarcharis your choice. Varchar stores ASCII data and should be your data type of choice for normal use.
A constant cannot be changed by the program while it is running. Furthermore, it does not take up any memory on the stack or in the heap, as it is inlined into the compiled code during the compilation process. They are used to represent unchanging data, such as the value of PI, or the date that a particular function was written. A variable is a memory location or register value that may be modified during the execution of the program, and represents data that is unknown until the program runs. Examples might include today's date, the number of times the user has logged in, or the user's preference in colors.
Metric is a measurement that can classify software or product quality and then process the quality of metrics. Matrix is a data collection mechanism, that uses collected data to derive metrics.
the difference between them is that direct access, such as a DVD allows you to go directly to a specific piece of data using an index, whereas sequential access is when data is chronologically stored on a VCR tape or Magnetic tape, you must go through all the data before you reach the data your looking for.
fundamental data type makes up the derived data type
Devices do not care with this difference. Humans do.
The simple is that fundamental quantities can be changed its not constant always and derived Quantities is like to constant always it could not be change ever.
1) Logical data structures are structures that emphasize on data relationships and how data is related from the view of the user. 2) Physical data structures are data models that emphasize on the use of efficiently and effectively storing data in memory.
difference between Data Mining and OLAP
Technically they're BOTH "data" files, it's just that one is organized in a way that it can be "executed" by the computer.
Data is the information that a program will act upon. For example, your data might be all of your financial records for the past year, and the program would be some piece of tax software. The program will act upon your data so that the appropriate numbers are placed in the appropriate fields on your tax return.
difference between serch data structure and allocation data structure
A project file is a file which contains information about your program. This could include source code, resources (images, sounds, etc.), and configuration files. A data file is a file which is actually used by your program to persist data between sessions.
SCHEMA is the physical arrangement of the data as it appears in the DBMS. SUB-SCHEMA is the logical view of the data as it appears to the application program.
The scope of work and the educational requirements are the difference between data communication and data communication information.
The difference between primary data and secondary data is that primary data is the information from the original research.
