Queries (Part 1)
Query… a very curious topic. Query and Question can be used interchangeably. Queries are sent to a computer system and are processed by a software program. One type of query, which many people perform many times a day, is a search query. Each time you search for something using a search engine, you perform a search query.
Search queries are divided into three different types:
- Navigational search queries
- Transactional search queries
- Informational search queries
What is a Navigational search query? A navigational query entered with the intent of finding a particular website or webpage. True navigational queries have very clear intent-the user has an exact site in mind and if you are not that site, you are not relevant to their needs. However, some queries that appear to be navigational in nature might not be. For example someone who searches Facebook should actually be looking for news or information about the company.
Now let’s study Transactional search query. A Transactional search query that indicates an intent to complete a transaction, such as making a purchase. Transactional search queries may include exact brand and product names or be generic. Many local searches are Transactional as well. Transactional search query has a subset which is called Vertical Search. Vertical searches represent people looking to make a transaction in a specific industry. They include local searches, restaurant searches, flight searches and so on.
The last one is Informational search query. Wikipedia defines this query as “queries that cover a broad topic for which there may be thousands of relevant results. Wikipedia leaves a lot to be desired for a lot of informational searches.
Structured Query Language (SQL) is the standard means of querying data in relational databases, though with proprietary extensions among the products. Structured Query Language is an indispensable skill in the data science. The uses of SQL include modifying database table and index structures: updating, ending and deleting rows of data and retrieving subsets of information from within a database for transaction processing and analytics applications. Also known as SQL databases, relational systems comprise a set of tables containing data in rows and columns. Users can create SQL queries that retrieve specific information from a database. For example, a marketing manager may perform a query on an employee database that selects all employees in a specific department that were hired between 10-11 months ago. The results might be used to provide the department head with current candidates for an annual review.
You may not always notice them, but computer queries are happening each day. For instance, most dynamic websites query a database each time you visit a new page. While there were exist many types of computer queries, their main purpose is the same, to receive an answer to a question.
Now you have a little more knowledge about what is a query, studied its various types. Next time we will continue to find more interesting features about different types of queries and will try to obtain more information about them. Thank you for your time and consideration, we hope you enjoy our articles.
