In Microsoft Access, there are several number field types, including Byte, Integer, Long Integer, Single, and Double. The Byte type stores small integers (0 to 255), while Integer can hold values from -32,768 to 32,767. The Long Integer type accommodates larger whole numbers, ranging from -2,147,483,648 to 2,147,483,647. For decimal numbers, Single and Double types are used, with Single having less precision than Double.

Formula

Tables, as we have learnt, are the building blocks of a database. It is a complete collection of data represented or displayed in rows and colums. While a database wizard completes this job, you need to create and design tables when yor create a blank database. Tables can also be created using a Table wizard, or by importing them from other applications like Excel

It checks for a live Internet connection whenever the Help feature is activated.

a field that is the same as one in another table

No. It does not designate any field you put in. That is something you have to do yourself. If you don't designate one, then it will ask you if you want to or if Access can put one in for you. If you allow Access to put one in, then it will insert a nwe field which will be an Autonumber field and this will be inserted at the top and so it will be the first field. It makes sense to have the first field as a key field, which is why it inserts it at the top, before the first field you put in. If you are setting your own, you should put that field in first, though you do not have to.

Access automatically creates an index for the primary key field in a table. In addition, Access automatically creates an index for any field name that contains the following letter sequences: code, ID, key, or num.

In a comma delimited file, data is stored as free-form text with each value separated by a comma. Text data may or may not be quoted and numbers appear with signs and decimals as appropriate. Example:

"my data", 1, 2.5, 3

A fixed format file stores each value in a fixed position in the record. There are no delimiters in the record and you must know the format of the record and fields to properly interpret the information. Numeric fields usually do not contain decimal points (decimal position is implied by the column format) and the sign may be in a leading position or trailing position, or it may be 'zoned', meaning the sign is indicated by altering the lead bit in either the leading or trailing character. Negative digits would appear as a letter.

In the above example, if it was fixed format with 4 fields with the first being text of 10 characters followed by 3 numbers with 6 digits with 2 implied decimal places (i.e. 9999.99) the data would appear as:

my data 000100000250000300

Well difference between maintaining and generating fields is simple. Simple table

Qty Bought Price Total paid (Calculated field)

1 £3 £3

2 £4 £8

Total is calculated field so when we maintain it we use a lilttle bit of memory to save the value and it will be always there for us so anytime we need it we just look it up. This however causes some problems if say the price will change we will need to update the field or else the data would be wrong. So in a large database if you have a lot of these calculated fields besides using a lot of memory you will need to update them frequently.

If however we generate a calculted field to find out total paid it may take a little longer time for the calcultaion but it will be updated and the value will be correct. In large databases I think generating calculated fields is a much better way to get data as it will save memory and time updating them.

Just about anyone who will use access will need to use a query (interrogated the data) at some point

You can use them, but it is not a god idea. You should look for alternate names for the fields if you get a reserved word warning.

No. MS Access is an application which uses a (sort of) DBMS. The power of the DBMS it uses is limited which is why it is not used for larger applications.
