In a database a field with a formula is called a calculated field. A calculated field should actually be in a table, as it can be calculated from data in other fields in the table, so it normally only appears in queries, reports and forms. In a spreadsheet it would just be a calculation.
They are under the category of Logical Functions.
Database Functions can and so can Statistical Functions. It depends on what it is you want to do.
Functions are basically built-in formulas in Excel. They are used extensively in Excel, so it is very important to know how to use them.
No. Excel is a spreadsheet package, not a file. You can use some basic database functions within Excel and you can also use Excel to store database information. However, in this respect, Excel is better for databases that are essentially flat files - Excel is not best suited for complex database structures.

There are thousands of formulas and more than a hundred functions used in Excel.
You could not really classify formulas into types as the amount of formulas are infinite and you can have a variety of things happening in a formula. Functions come in categories, and that is maybe what you mean. It will depend on which version of Excel you have, but these are the categories available in later versions: Cube functions Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions
All formulas recalculate when Excel opens, so if a database in Excel has formulas in it, it will be recalibrated. It could also be linked to another file or external source which may make it change when it is opened.
Excel is not a database itself, but a lot of spreadsheets by their nature are databases in their structure if laid out like a table. Excel also provides a range of database facilities and inbuilt database functions. Amongst the facilities are the ability to sort and to apply filters and use forms to enter data. The inbuilt functions mainly correspond to other functions in Excel, except that they can be done with criteria applied to the database. So like the SUM, MIN and MAX for example, there are functions called DSUM, DMIN and DMAX, amongst others.
Built-in formulas in Excel are known as functions. Here are five common ones: SUM AVERAGE COUNT MIN MAX
