Very simply, Microsoft Access is an information management tool that helps you store information for reference, reporting, and analysis. Microsoft Access can help you overcome the limitations found when trying to manage large amounts of information in Microsoft Excel or other spreadsheet applications. |

| The value any database can provide is to store related information in one place, and then let you connect various different things together (sometimes called "entities" in database speak). You store one version of the truth for any given thing, like a client, a DVD, or an order. Some of the major benefits to using a database are: | |

Microsoft Access works in the same manner any database does, by storing related information together, and letting you create connections (commonly called relationships) between different things. The relationships between two different things can be very simple (such as a contact at a customer and the customer itself) or complex. In the example below, the blue boxes represent the major things we're tracking in our MS Access database tables, and the reports at right show how you can join the related information for analysis and reporting.
Data is stored in Microsoft Access tables (think of them as mini-spreadsheets that store only one type of thing). A table can have many fields (think of them as columns in your spreadsheet). Each field in a table can be set up to allow or prevent users from entering certain information (for example, you could say one field only accepts dates, another can only allow a user to enter a numeric value, while another lets them enter anything they want).
Once you have your MS Access tables, fields, and relationships set up, you can create data entry forms that use those tables to store your information and later create reports with the data. Microsoft Access forms are incredibly easy (and fun) to design with a wysiwyg form design tool. And you can use MS Access forms to simplify data entry for users by grouping related fields together, and hiding fields they don't need to enter. The Microsoft Access Command Button Wizard even helps you to create simple buttons for your forms without understanding how to create macros and Visual Basic.We've put together the following comparison table to help you decide whether Microsoft Access may be the right solution for you.
| Use | Spreadsheet (Excel) | Desktop Database (MS Access) | SQL Server or MySQL with Access as the user interface |
| Validate basic user input (e.g., for a single field/cell | Yes | Yes | Yes |
| Complex user input validation or events (if field X = Y, and field Z is empty, perform some action) | Challenging to accomplish | Yes | Yes |
| Data arranged in a few columns without much repetition | Yes | Yes | Yes |
| More than 65,535 rows/records | No | Yes | Yes |
| Simple cross-references | Yes (vlookup and hlookup) | Yes | Yes |
| Complex data analysis/queries | Limited | Yes | Yes |
| Events based on user actions (when user exits a field/cell do X, when they mouse over a field/cell do Y) | No | Yes | Yes |
| Multiple users, but generally accessing data at different times | No | Yes | Yes |
| Multiple users, accessing data at the same time | No | Yes (but can be slow depending on network speed) | Yes |
| Frequent mass-update operations | Challenging to accomplish, time intensive | Yes | Yes |
| Multiple data entry forms | No | Yes | Yes |
| Mail Merge with Word | Yes | Yes | Yes |
| Reporting | Challenging to accomplish | Yes | Yes |
| Automated backups | Challenging to accomplish | Possible with VB coding or backup software | Yes |
| Record-level auditing | No | Possible with VB coding or UI Builder for Microsoft Access | Yes |
| Ability to hide the inner workings of your project from the user | Challenging to accomplish | Yes (MDE files) | Yes |
| Expertise Required | Low | For simple databases: Low/Moderate For complex requirements: Moderate-to-High | High |
