What are the Access data types and how they are used?
In Access and in databases in general each field in a database table is of a certain data type. The data type determines what type of data a field can hold. A field of the text data type can hold text, a field of the number data type can hold numbers and a field of the data/time data type can hold date and time values.Access actively checks what type of data is entered into a field and Access will disallow the entry of data into a field that doesn't conform to the field's data type. Access won't allow you to put text into a field of the Number data type, for example.So, data types are a way to restrict the entry of data into a field. Internally, the database uses different strategies for the storage and retrieval of different data types.

What type of data is access best at handling?
Databases are used to hold many kinds of data. You could not say that Access, or any other database, is best at handling any particular one. Commonly, text data is a regular data type used, such as in details about people. If you are doing a lot of calculations a spreadsheet may sometimes be better than a database for numbers, but a database can do lots of calculations too. Databases can store dates, logical values (Yes/No), pictures and so on. A database such as Access is designed to deal with data, so it is often what you want to do with that data that may influence how you store and process it and what application to use, rather than the data type itself.
What is a field length check in a database?
Most database field types have an inherent data length limit, however the business rules of the application may require a lower maximum limit on the field.

Why YOU choose database system instead of simply storing data in OS?
Operating System (OS) files do NOT hold data for your personal use. Any data in an OS file is used STRICTLY by the OS. A database system is used for storing data of any kind. A text file is not stored data, so you wouldn't use a database for THAT. But a dictionary of words used in the text file, along with their definitions, could use a database. Even pics can be stored in a database, and even a list of other files can be stored in a database. by:Mohammed Abu Lamdy
