Microsoft Access is a database tool that helps you understand your information and provide a easy way to access, enter, and navigate your data. One of the tool that I have problem understanding in Microsoft Access is the "Queries". What is queries? Queries allow the user to ask questions and being able to answer these questions. For example, if you have a data file with all the cell phone numbers you have on your phone. Input the criteria you want, for example female. All the cell phone numbers belong to a female friends will be listed.
Now my second question is when should I use Microsoft Access or Microsoft Excel since they share so many similarities. To decide which is the best program to use, we all need to answer this question first: is the data relational or not? Data that can fit into a single table of worksheet is called nonrelational data or flat. For example, if you are creating a list with data that can fit into a worksheet, then Excel is the right program. If you are creating a more complex list, then Access is a better choice.
