What is string array?
A string array is an array whose contents are strings.An array is when you use a single variable names to store different data items. The data items are distinguished by a number (sometimes by more than one).A string is a data type used to store texts. It may contain letters, digits, or other symbols.A string array is an array whose contents are strings.An array is when you use a single variable names to store different data items.

The first row of a table used as a data source should contain?
Column Names.
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
What components should an implementation ready data model contain?
A description of the data structure that will store the end-user data.A set of enforceable rules to guarantee the integrity of the data.

Which database object does NOT contain data?
Database indexes do not contain data; they are structures that improve the speed of data retrieval.
What data does the computer record?
Computers record data in the form of "bits", Binary Digits.
What is the advantage data in a table over data presented in a paragraph?
number of digits that can be included
What determines the kind of data that a field can contain?
The data type of a field determines the kind of data it can contain. For example, a field with a data type of "Text" can contain letters and numbers, while a field with a data type of "Number" can only contain numerical values. The data type is set when designing the database schema.
What does symbolic data means-?
Symbolic data differ from standard data in that they contain internal variation.
What device works with discrete data or digits?
analog
Difference between data validation and data verification?
Data validation means to check for correctness, meaningfulness, and security of data that are input to the system. The simplest data validation verifies that the characters provided come from a valid set. For example, telephone numbers should include the digits and possibly the characters +, -, (, and ) (plus, minus, and brackets). A more sophisticated data validation routine would check to see the user had entered a valid country code, i.e., that the number of digits entered matched the convention for the country or area specified. Data validation might also check that all required fields are filled in before an online form was submitted. Data validation should also check that only data of an appropriate length is accepted. Failure to do so can make an application vulnerable to buffer overflow exploits. Validation should also prevent users from entering command strings in place of data. Data verification is a process that helps to determine whether data was accurately translated when data is transported from one source to another, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous data loss.
