Yes, a query is a question you ask to retrieve specific information from a database. It is a command written in a specific language like SQL that allows you to interact with the database to perform operations such as selecting, updating, or deleting data.

A database "query" is basically a "question" that you ask the database. The results of the query is the information that is returned by the database management system. Queries are usually constructed using SQL (structured query language) which resembles a high-level programming language.
A "query" is usually a programmatic statement that is understand by a DBMS(Database management system) that understands how to access and manipulate data within a database. The primary operations of a query are referred to as CRUD(Create, Read, Update, Delete) and the main programming language for writing queries is ANSI SQL.
In XML data storage, the data is stored in a file which represents an XML Schema of the data. To read the data, you have to pull and open the entire file in memory and use technics like xpath to get the data element you want. In SQL data storage, the data is stored in a database ( usually relational database). To read the data, you simple sent an SQL query to the database. The database management engine analysis the query and get the required data elements you ask for in your query which is finally sent to you as a reply.

This is not a programming issue; simply ask permission from the owner/administrator of the database in question.
Database as the name suggest is the collection of records or data that are related to each other. There are mainly three type of database network database, object oriented database and hierarchical database. Database helps in maintaining data consistency and data integrity.
A query is in basic terms a QUESTION. Therefore when you make and run a query in access you are asking it questions to do with the data it has in the dataset. I.e In the last name field you may ask for all people who meet the criteria of SMITH as the last name. Queries can be very complex depending on what youve stored in the database and what your asking of it.
