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.

A database object that retrieves specific data from one of more tables is a what?
A database object that retrieves specific data from one or more tables is called a query. Queries are used to extract information from databases based on specified criteria and are essential for data manipulation and reporting purposes.
A database object that retrieves specific data from one or more tables?
A stored procedure is a database object that retrieves specific data from one or more tables by executing a pre-defined set of SQL statements. It can accept input parameters, process the data in a controlled manner, and return the desired result set for use in applications or reports. Stored procedures help improve performance, maintain data integrity, and simplify complex queries in a database system.
What is it when an object allows a user to select a subset of fields or records from one or more tables?
This is known as a query in database management systems. Users can use queries to filter and retrieve specific information from one or more tables based on certain criteria. It helps in extracting relevant data without having to browse through all the records manually.
What is view of data in dbms?
In a database management system (DBMS), a view is a virtual table derived from one or more base tables. It allows users to query or manipulate data without directly accessing the underlying tables, providing a layer of abstraction and security. Views can simplify complex queries, hide sensitive information, and provide a consistent interface to the data.
What is a database in which ALL the data is stored in a single table known as?
A database in which ALL the data is stored in a single table is known as a flat-file database. This type of database lacks the relational structure found in more traditional databases that use multiple tables to store and organize data. Flat-file databases are simple but may limit the ability to efficiently query and manage data.

What is the advantage of denormalization over normalization?
If you meant disadvantage of normalization then these are the answer for your query. More tables to join: By spreading out your data into more tables, you increase the need to join tables. Tables contain codes instead of real data: Repeated data is stored as codes rather than meaningful data. Therefore, there is always a need to go to the lookup table for the value. Data model is difficult to query against: The data model is optimized for applications, not for ad hoc querying.
What is an add query?
An add query, more commonly known as an Append query, allows you to add records to a table. It can combine data from two tables, reading data into one of the table. There must be compatibility between the tables, like having similar fields. You could have two tables with names and addresses and having corresponding fields. They could then be transferred into the corresponding field. If there are no compatible fields, then it can't be done.An add query, more commonly known as an Append query, allows you to add records to a table.

Does retrieving data from two related tables require the creation of a query for each table?
No. One query can take data from more than one table. You would just need to make sure that you have set up the relationship between the tables that you put into the query. You also need to be careful about how you choose the fields and how you set the property of the join between the tables. If you don't do it properly you can get unexpected results.
How do you make a query on Microsoft access?
Open a new query. Bring in the table you want to append records from and add in the fields you want to use. Click on the Query menu and pick Append Query. Choose the table that you want to append to from the drop down list. In the Append To line of the query design grid you can choose the corresponding fields you want to append to. When you have them chosen and applied any criteria, then you can run the query. Before changing to an Append query it is often best to first set it up as a Select query so that you can see what records and fields will be appended when it is run. You can be more certain then that the correct records will be added.
What is query in access?
The purpose of a query is to extract information from a table or tables, which can be based on some criteria. It can be something simple, like list all names in a table, or something a little more complex, like list all products that are priced over certain amount. A query can be very simple or very complex, depending on your requirements.
