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.
How are significant digits related to calculations using measurements?
Significant digits, or significant figures, reflect the precision of a measurement and convey the reliability of the data. When performing calculations with measurements, the number of significant digits in the result should be determined by the measurement with the least number of significant digits. This practice ensures that the final answer accurately represents the precision of the input data, preventing false precision and maintaining the integrity of the calculations.
How is a check digit used as a validation check?
A check digit is used in validation checks to ensure the accuracy of data entry or transmission. It is calculated based on the other digits in a numerical code using a specific algorithm, such as the Luhn algorithm for credit card numbers. When the data is entered or transmitted, the receiving system recalculates the check digit based on the other digits and compares it to the original check digit. If they match, it indicates that the data is likely valid; if not, there may have been an error in input or transmission.
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.

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?

Which database object does NOT contain data?
Database indexes do not contain data; they are structures that improve the speed of data retrieval.
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.
