Queries in database definition
Query is another word for question. In fact, outside of computing terminology, the words "query" and "question" can be used interchangeably. For example, if you need additional information from someone, you might say, "I have a query for you." In computing, queries are also used to retrieve information. However, computer queries are sent to a computer system and are processed by a software program rather than a person.
One type of query, which many people perform multiple times a day, is a search query. Each time you search for something using a search engine, you perform a search query. When you press Enter, the keywords are sent to the search engine and are processed using an algorithm that retrieves related results from the search index. The results of your query appear on a search engine results page, or SERP.
Another common type of query is a database query. Databases store data in a structured format, which can be accessed using queries. In fact, the structured query language (SQL) was designed specifically for this purpose. Users can create SQL queries that retrieve specific information from a database. For example, an human resources manager may perform a query on an employee database that selects all employees in a specific department that were hired between 11 and 12 months ago. The results might be used to provide the department head with current candidates for an annual review.
While you may not always notice them, computer queries are happening all the time. For instance, most dynamic websites query a database each time you visit a new page. Software applications often contain background functions that perform queries based on your input. While many types of computer queries exist, their basic purpose is the same — to receive an answer to a question.
NOTE: The word "query" can be used as either noun or a verb. For example, you can "perform a search query" or "query a database." Both examples are correct uses of the word "query."dress dupe 40 haircut how coffee list of heavenly bodies in solar system haircut time haircut best lifestyle for men cheapest designers at revolve after the fashion job trend astronomy women too coffee hair highland village fashion about fashion for now life trends views of the stars at night facebook lifestyle lifestyle choice astronomy scale info astronomy coffee times thai hair coffee's on coffee art 2014 trend 6 science coffee table with lift top having coffee with her what is your fashion women cold outfit third brightest star in the sky great clips idaho falls coupon two floor coffee shop murray coffee cake banana bread haircut ad game of fashion man coffee coffee enema weight loss new trends are winter fashion cute coffee law coffee in world profile coffee shop stand coffee sales lifestyle slinky dress green sparkles by fashion one line coffee competitors coffee with you gary allen virginia beach astronomy au street style spring 2018 lulu yellow trends book system trend guide astronomy power haircut today's lifestyle who was the science women style guide haircut 2008 sciencedirect error team fashion science in life you are so fashion play lifestyle car trend astronomy course astronomy report bohemian embroidered romper fashion 20 s anoxia at birth abc haircut low lifestyle trending videos on youtube trending videos facebook astronomy means coffee shop names coffee shops mountain view ca whats a scientific method fix the coffee every song to be on youtube trending high coffee trend water cellular respiration oxidizing agent women haircut photo scientific method steps in order haircut play white lifestyle trending hashtags instagram 2019 olivia hair hair salons near me 3 science it in fashion study of space and planets stock haircut 3rd avenue studio denver science 2014 street fashion trends 2017 fall 4 fashion lifestyle photo shooting science of reading lifestyle women dresses trending into fashion price coffee in astronomy right haircut training lifestyle astronomy cast trends for him lifestyle party 3 2 1 haircut trending news google game in science the top trend in films-2016-2017 2 fashion health lifestyle fashion and new car coffee coffee night 2 cups of coffee set engineering and astronomy more is more fashion what in fashion coffee grinder burr people astronomy red maxi dress tie waist my world science pacific plate best colorado local coffee dupatta wearing styles of lehengas fashion game s astronomy items soil compaction science project science fair projects 5th grade hair design in live oak area coffee bar war trending hashtags 2018 on the trend coffee work is draco a zodiac constellation after having a coffee how to look stylish in the snow haircut cut bank trend lifestyle home trend season starships book coffee what kind of things happen in space coffee beanery haircut 56 constellation of canis minor company coffee trends city trending tops for women 2022 hair trends for all women 2018 lifestyle credit fashion book is this fashion science year 1 can you block trends on twitter lifestyle community astronomy review lifestyle image space lifestyle why do stars revolve around polaris coffee story science buddies bibliography
