Hi,
"Data AAccess Objects" often time refers to objects at the 3rd tier. Their objective is to connect to the data source, which can be database engine like sql, file type doc like xml...etc


"Businss (logic) objects are refers to objects that handle logics at the 2-tier. Their objective is to process information you recieved from the first tier. Do the nesscary process to ensure certain logic (policy) applied. Then pass the value to 3-tier and write to the database...etc

They are all objects with diff objective.
