What is the difference between query datasheet and a table datasheet?
A query datasheet displays the results of a query operation, showing data based on specified criteria or calculations. A table datasheet displays the data in a table format, representing information stored in a database table. In essence, a query datasheet is derived from a table datasheet and is dynamic based on the query criteria.
What records allow you to pull data from a table so that you can analyze or manipulate the data further?
Database management systems (DBMS) allow you to query a table using SQL (Structured Query Language) to pull specific records or data that you need. By constructing a SELECT statement, you can filter, sort, and extract data from a table based on your criteria. This data can then be further analyzed or manipulated using various tools and techniques depending on your needs.
When you want to extract data from two or more tables you use an query?
When you want to extract data from two or more tables, you can use a SQL JOIN query. By using JOIN clauses, you can combine rows from different tables based on a related column between them. This allows you to retrieve data from multiple tables in a single query.
How do you extract information from relational database?
You can extract information from a relational database using Structured Query Language (SQL) queries. By writing SQL queries, you can retrieve data by specifying the table, columns, conditions, and sorting options to meet your requirements. This allows you to extract specific information from the database based on your criteria.
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.
What are subqueries used for in a database?
A subquery is basically a query inside another query. Sometimes a main query needs to process data that is the result of another query. To extract that data a subquery could be built into a field in a main query. This is known as a subquery.A subquery is basically a query inside another query.

What query do you use to extract data from two tables?
You would use a JOIN query for this.
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.

If you delete query does it delete the original information in the table?
Your question is unclear. If you mean if you delete a query, then it does not affect the data in the table. Deleting any kind of query does not affect the data in any table it uses. If you mean if you run a Delete query, then yes the data in the table will be deleted. That is what Delete queries are for.

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.
Is there a Database program and or a Spreadsheet program that can easily locate and delete duplicate entries?
Microsoft Access can easily locate and remove duplicate records from a table of data. The data is stored in a table, and a query is used to extract the duplicate records. You need to click on "new" query and a box will popup asking what sort of query you want to create. Pick the "find duplicates query". follow the wizard instructions and it should be quite clear. Any problems let me know.
What adds deletes or changes data in a table?
