In everyday life, an object is an entity that displays or provides some characteristics that set it apart. These characteristics are used to describe the object. For example, an object called Car has such characteristics as its make, model, color, year made, price, and mileage, etc. When put together, these aspects can be used to get good knowledge of what the object looks like and perhaps how it functions. The same concept is used in computer programming, in database development, and in Microsoft Access.

	Introduction to Data Analysis Microsoft Access / Data Manipulation Data analysis provides the user with the ability to examine a database's records and the overall behavior of its objects. Data analysis is performed on tables, queries, and/or forms.
