When Access first creates a database it automatically creates a table.?
Yes it does. However the table is blank and the user must then start to create the fields they want. So Access really only starts the process of creating a table and the user must do the rest.
In a database what is a field width?
It is the amount of space that you want to allow for some data. Different kinds of data will take more space than others, so you should define how much space is needed. So if you had a field for Gender, then the values would be Male or Female. So a maximum of 6 letters is needed, so you could specify that as the field width. If you set it larger than that you would be allocating space that was not needed, and you would be wasting space. For other things, like names or address lines, you would need more space than for your gender field, so you would set them to have more space. Some fields have their widths automatically set, like date fields, so you don't need to specify anything.
Field names can be a maximum of how many characters in length?
Field names can be a maximum of _____ characters in length
When you enter data into a form where does it go?
In Microsoft Excel, the data stays in the cell where it was entered. If that cell is referenced by an external source, it will also be copied to that external source. The location cannot be determined from Excel, only from the external source.
No, it does not appear on the datasheet or form. It is really just for design purposes to tell the designer and anyone else that may be changing the design, what the field is for. Sometimes it is very obvious, like Date of Birth or nationality, but sometimes a field may be more obscure, like if it is for some special codes that a company uses to designate products. If you want something on the form, you can use the caption option or type something into a text box beside the field to explain its purpose.
Why reports are important in access?
Reports can give you structured print-outs of your data. They can allow you to get different types of details, like grouping data and getting sub-totals and totals. They can allow you to pick just certain data and do things like present it in a sorted order. You can have different kinds of headings on a report, making it clearer what it is the report is showing. This can all make the data more meaningful and useful in presenting the data to people who need to analyse it or distribute it.
What does descending mean in Microsoft access?
Descending order is when you sort numbers from largest to smallest, or sort text from Z to A (in reverse alphabetical order), or dates from most recent to oldest. Usually we sort in ascending order, but sometimes we want to format in descending order.
How do you link two or more access table?
Creating Relationships between Tables Relationship is an association established between common fields (columns) in two tables. A relationship can be one-to-one, one-to-many, or many-to-many. When you create a relationship between tables, the related fields don't have to have the same names. However, related fields must have the same data type unless the primary key field is an AutoNumber field. You can match an AutoNumber field with a Number field only if the FieldSize property of both of the matching fields is the same. For example, you can match an AutoNumber field and a Number field if the FieldSize property of both fields is Long Integer. Even when both matching fields are Number fields, they must have the same FieldSize property setting. Opening the Relationship window 1. Click Tools Menu

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.
