What do mean by query language and its needs?
Query Language is way for communicating from the database. It work as a interface between user and the Database. its not possible to generate a result from database without query language. Query language helps us to communicate with database.
The query uses the data that?
A query is a way of extracting information from a database, usually by using certain criteria or requesting certain data
What is the purpose of a report?
To display data returned from a query in a specific way.
What does sorted mean?

Why would a query be used to retrieve information from a table rather than just accessing the table data directly?
A query can extract records in all sorts of ways, like finding ones that meet some criteria and listing them all together. It can do that very fast. If there are a huge amount of records, trying to extract them manually would be a very slow process. A query can extract data in different formats and even convert it to make it look different to the way it is in a table. It could be something simple like listing the extracted data in upper case. A query can also do all sorts of other things, not just extract information. Queries can be used to delete things or add data or update data and other things. A query is an essential element of a database. Without them you might as well just have your data on paper.A query can extract records in all sorts of ways, like finding ones that meet some criteria and listing them all together.

How do you know if something is a simple or complex query?
One is a simple way of doing it and one is a complicated way of doing it.
What is query Optimization?
Queries of a database can be fast or slow. Depends on a lot of things. The size of the table, the amount of data you are requesting from the query, etc. One of the ways a dba can help query optimization, is by "updating statistics" on a table. Statistics of a table allows the query to find the most efficient way to gather the data from the table.
What is the database term query?
In the context of databases, a query refers to a request for retrieving, updating, or manipulating data stored within a database. It is a way to communicate with the database to perform operations such as data retrieval, insertion, updating, and deletion based on specific criteria. Queries are typically written using query languages like SQL (Structured Query Language) to interact with databases.
When would you use a crosstab query instead of a select query?
A crosstab query is a type of select query, but it displays the data in a different layout. A crosstab query can present data in a tabular layout which can sometimes be easier to follow than the way a standard select query does, although they will both show the same data. Say you were counting the amount of males and females that worked in each department of a company. A crosstab query will present the data in a table, maybe having the male and female headings at the top over 2 columns and the names of the departments down the side for each row. A Select query will take more lines to present the data. So for those kinds of situations using a crosstab query is better.A crosstab query is a type of select query, but it displays the data in a different layout.

Why database system support data manipulation using a declarative query languages?
Declarative query languages allow users to specify what data they want without specifying how to retrieve it. This abstraction simplifies the querying process and allows for optimization by the database system to determine the most efficient way to execute the query. It also enhances portability and adaptability by separating the query logic from the database structure.
