When was a beautician first invented?

You can't invent a "beautician". That is an occupation. Perhaps you should rephrase your question to something like, "When did someone first solely devote their timie to the beautification of another person?"

When it comes to processor speed what is the best advice you would give someone?

Get the fastest processor available to them in their price range.

With the cost of dual core CPU's coming down literally on a daily basis, these are what I recommend to all of my customers now.

Then from finding out what they want the PC / CPU to do, be it normal internet, office applications or games etc, then you choose the best CPU for their needs.

IE no need for a quad core 3.0 ghz, CPU for a woman who occasionally uses the net to surf, and does the odd letter..

In this case, id opt for a simple P4, 2.0Ghz onwards etc..

Hope this helps

be safe

Who decides size of data types in a language?

The people who create the language take the liberty of deciding the size of data types in a programming lanauage.

If you (as a programmer) create your own custom data type, for example by defining a class, then you decide what goes into it - for example, in Java, if one of the pieces of data requires an integer, you have the choice of storing it as an int, which uses 4 bytes, or as a long, which uses 8 bytes (and permits larger numbers).

How do you explain in detail the role of dba also explain oracle tools available?

The database administrator performs a critical role within an organization and is an important and key role in Database Management Systems. The major responsibility of a database administrator is to handle the process of developing the database and maintaining the database of an organization. The database administrator is responsible for defining the internal layout of the database and ensuring the internal layout optimizes system performance.

The database administrator has full access over all type of important data of an organization. The database administrator decides what data will be stored in the database and how to organize data in database so that it can be access easily on requirement or need of an organization. To design the database of an organization, the database administrator must have a meeting with users and determine their requirements.

What does the term primary key mean?

The primary key refers to the field in a database that would contain only unique values. For every row in the table, the value in this field would definitely be unique.

for example in an employee table, the employee number field would be the primary key. no two employees would have the same employee number.

What are the advantages of spreadsheet?

A spreadsheet is, in it's most basic form, a large calculator. It's purpose is to perform both simple & complex mathematical calculations. Spreadsheets are extremely powerful and are used for 'number crunching' - (calculations on lots of figures) and also allow mathematical formulae to be applied. A good example of spreadsheet use would be to calculate sales profits for the current year which need to be presented in a graph. The range of formulae that can be applied is vast and ranging from the most basic (adding two numbers together) to complex calculations such as applying 'what if' scenarios. The spreadsheet should not be confused with a database (although it has limited database functionality) and should not be used to store mailing lists or other data records - this is a common mistake (see above the reference to somebody using a spreadsheet to create a resume). The sheet itself is comprised of columns (vertical) and rows (horizontal) which are in turn, made up of cells. It can be used for keeping small business accounting records if the company does not generate enough revenue to warrant the cost of accounting software. In short: the main advantage of a spreadsheet is when complex mathematical calculations need to be carried out on large amounts of numerical data. It's a powerful, complex calculator.

Where can you get a database?

You can get many free database applications, like Open Office Base. You may already have an application to create databases, like Microsoft Access. Once you have such an application, you can then create your own databases. If you are looking to get an actual database with data in it, then it would depend on what kind of data you are looking. A lot of data is private and so if someone has a database, they are often legally not allowed to share it with you, like if it was storing personal data.

What is the best source to create form should it from query or table?

There is no definitive answer to that, as it depends what you want on the form. Ultimately all data comes from tables. If you just want to show all the records as they are you could base the form on the table. However if you want to display only selected records or certain calculations, you might create a query to do those operations and then base the form on the query.
