Data collected after any research to gather primary data.
Primary key that is used to identify a record uniquely. Primary key is a key that always unique and not null. A system generated primary key is called surrogate key.Primary key is the one which is always unique and not null. Advantage of primary key that it helps in identifying a tuple uniquely.
The word is "prime number". 871 is a multiple of 13.
Primary Data An advantage of using primary data is that researchers are collecting information for the specific purposes of their study. In essence, the questions the researchers ask are tailored to elicit the data that will help them with their study. Researchers collect the data themselves, using surveys, interviews and direct observations (such as observing safety practices on a shop floor). answers to specific information Secondary Data There are several types of secondary data. They can include information from the Census, a company's health and safety records such as their injury rates, or other government statistical information such as the number of workers in different sectors across a country. Both primary data and secondary data have their pros and cons. Primary data offers tailored information but tends to be expensive to conduct and takes a long time to process. Secondary data is usually inexpensive to obtain and can be analyzed in less time. However, because it was gathered for other purposes, you may need to tease out the information to find what you're looking for. The type of data researchers choose can depend on many things including the research question, their budget, their skills and available resources. Based on these and other factors, they may choose to use primary data, secondary data - or both.
In 2003, a group of researchers reported on a new genetic mutation associated with primary amenorrhea.
One advantage of a secondary source over a primary source is that it may provide analysis, interpretation, or synthesis of information from multiple primary sources. This can offer a broader perspective or deeper understanding of a topic compared to individual primary sources.
A secondary source summarizes complex subjects by synthesizing multiple sources.

Data collected after any research to gather primary data.
The major advantage is the a secondary cell is rechargeable, and in the long run, may not cost at much as constantly replacing a primary cell.
Two possible problems that a researcher should be aware of when using primary sources are bias and authenticity. Primary sources can be biased based on the perspective of the author or creator, so researchers should critically evaluate the information presented. Additionally, researchers should confirm the authenticity of primary sources to ensure that they are trustworthy and reliable for their research purposes.
