Yes, that is what data integrity is all about.
What are the disadvantages of Microsoft PowerPoint to Microsoft Access?
SQL - Structure Query Language for MS Access is not as robust as you get on some other RBMS like MS SQL Server, Oracle etc. SQL gives you the flexibility of of data definition and manipulation using script. Pelumi (Nigeria)
What is autonumber field in access?
Automatically stores a number that is one greater than the last number used. It is used to identify a record by acting as a Primary Key. A Primary Key is unique and cannot be left blank. Even if a number is deleted, that number will never be used again, ensuring that each record can be uniquely identified. You do not have to enter the value. It will automatically enter itself. You also cannot change it.
What are the different relationships in Access table?
One-to-many Relationship
This kind of relationship allows one field to be related to many separate fields. For instance, one customer in a database may have multiple orders. Therefore, one field, the customer, will be related to multiple fields, the orders.
Many-to-many Relationship
This kind of relationships allows many fields to be related to many other fields. For instance, an order can contain many products. Also, a single product may be on multiple different orders. In this case, you would have to use a many-to-many relationship.
One-to-one Relationship
In this relationship, one entry in a given field is can only have one related entry in the second field. This can be used for matching customers to other information about that customer, such as phone numbers and mailing information.
What is blank database in MS Access?
When you create a new database it is blank or based on a template. You can choose to base one on a template in which case there will already be some things in it, like tables that are in the database that you can use as a starting point. You may want to do this sometimes for a standard kind of a database. Other times the database you are creating is not like any other, so you would start with a blank one and create all the elements yourself.
How to create a relationship in access?
Creating a relationship in MS Access can be done in more than one way, but the most popular way is by using the Relationships screen. In MS Access 2010, to open the Relationships screen go to the Database Tools tab and then click the Relationships button on the ribbon.
On opening the Relationships screen Access will show you the Show Table window. In this window you can select the tables that you want to create relationships for. You can add more tables to the Relationships screen later by dragging them onto the screen from the list on the left.
In order to create a one-to-many relationship select and drag the primary key of a table over a field in another table and release the mouse button. This will open the Edit Relationships panel, which allows you to set the properties of the relationship.
How do you called a row from excel in Access?
In Access, a row from a spreadsheet is normally a record.
Forms within Access can be either bound or unbound. A bound form means that the form and your data table are connected and that they depend on each other. Information entered into a bound form changes the cell within the spreadsheet that has the same label. For instance, when you put an age into an "Age" field in a form, it also updates the "Age" cell in that row or column on the spreadsheet. Unbound forms have no relationship with the data in your database, but they have several other uses.
Switchboards are a type of unbound form that you can use to create menus for your database. Since a switchboard is not related to the actual data, manipulating a switchboard form does not alter your data within the cells. Utilize switchboards to create menus to open and close databases or to create a menu that enables you to create and access different forms. Think of a switchboard as a form that gives the end user options for actions.
Another unbound form is a dialog box. These forms are not connected to data in the spreadsheet, so data can't be changed when using dialog boxes. Choose a dialog box when you want to create dialog after a user action. For example, use dialog boxes when creating prompts or results from a search that the user performed. Think of dialog boxes as forms that result from a user taking a particular action.
A data entry form is a bound form that affects the data within a spreadsheet. You can customize these forms to include different fields that relate to cells within the database, and you can further enhance the form by adding tabs to organize the form. When a user enters data into a data entry form, the database is updated with the new or changed information. Data entry forms may also be used to view related sets of data that you choose, such as a customer's name and address or phone number.
Is there a database program similar to Microsoft Access for Linux?
They also have a developer version that you can create databases to give to anyone that will work without them having to purchase the full version. The version it creates to give away has some limitations, but it works great.
I use it for some pretty sophisticated stuff.
What do you mean by metadata in MS Access?
Metadata is data about data. MS Access is a database. Most of the time we are interested in the data in the database tables. For example the database could have tables that store information about orders and order items. So typical queries would be for the number of orders per day or from some location. Metadata would tell us things like the names of the tables and the names of the columns in those tables.
What is the purpose of generating Reports?
If you want a report to only use certain fields, and particularly if you want it to work with only some records that meet a criteria, it is better to create a query to extract what you want first and base the report on that. You can also include multiple tables and calculated fields in a query easier than trying to do it in a report. It is better to get a query to do the work of extracting fields, records and using criteria than trying to do it in a report. So it is a common thing to create queries for the purpose of extracting the data you want for a report.

How do you create a parameter query?
Open a new query in Design view and add the table you want. Add the fields you want into the design grid. Under the field you want to be able to have a parameter for, in the Criteria row enter a meaningful message inside square brackets. So if you were looking for the user to enter a department that would then be used as the criteria, you could have something like the following in the Criteria row under that field:
[Enter a department]
When the query is run, it will prompt you with whatever has been typed into the square brackets and you can then type in what you want into the dialog box that pops up. Whatever you type will be used as the criteria. It is not important what exactly is typed into the square brackets. It is the square brackets themselves that are important. Without them, what you type in the criteria could be treated as text and have quotes put around it, or as a number or whatever the data type of the field is. Access does not know what the text in the square bracket means and it is asking you for something, which is how a parameter query works. You can also use some operators with it. So if you wanted to only show values above a certain level, you could put the greater than sign before the parameter, like this:
>[Enter a value]
What you seem to be describing is a Query. Databases run queries when the humans want information out of the database. Microsoft Access has a separate Table structure for creating and running Query. The correct answer is called a Run.

What is the difference between database and table?
A table is an object inside a database. A database has tables of data, views, indexes and programs. A database can have 10 or thousands of tables.
More specifically, a table is a collection (rows) of data on a single related topic. For example, the Employees table would have employee data, each row being a different employee, but it would not have Inventory data. That would be in the Inventory table.
A database is a collection of objects, primarily tables, but also indexes to help search the tables, views that filter, select and combine the data in the tables, and stored procedures (pre-defined programs that perform specific actions on the database).
