Advertisement Microsoft Access is arguably the most powerful tool in the entire Microsoft Office suite, yet it mystifies (and sometimes scares) Office power users. With a steeper learning curve than Word or Excel, how is anyone supposed to wrap their head around the use of this tool? This week, will look at some of the issues spurred by this question from one of our readers. A Reader asks: I’m having trouble writing a query in Microsoft Access. I’ve got a database with two product tables containing a common column with a numeric product code and an associated product name. I want to find out which products from Table A can be found in Table B. I want to add a column named Results which contains the product name from Table A if it exists, and the product name from Table B when it doesn’t exist in Table A.

The Microsoft Excel Viewer is the latest version of the viewer. It can read the file formats of all versions of Excel, and it replaces the Microsoft Excel Viewer 2003. For more information about opening a workbook, viewing a worksheet, working with data, and printing by using the Excel Viewer, see the following Help file.

There are other arcade emulators that emulate sub set of what MAME is doing. (on serious note: MAME is a name of program. Depending on what OS you are using and what some of arcade games that interest you particularly, there are other 'easier' to use software.) see this list. The biggest arcade emulator project.

Do you have any advice? Bruce’s Reply: Microsoft Access is a Database Management System (DBMS) designed for use on both Windows and Mac machines. It utilizes Microsoft’s Jet database engine for data processing and storage. It also provides a graphical interface for users which nearly eliminates the need to understand Structured Query Language (SQL). SQL is the command language used to add, delete, update, and return information stored in the database as well as modify core database components such as adding, deleting, or modifying tables or indices. Starting Point If you do not already have some familiarity with Access or another RDBMS, I would suggest you start with these resources before proceeding: • For a programmer or a technology enthusiast, the concept of a database is something that can really be taken for granted.

However, for many people the concept of a database itself is a bit foreign. where Ryan Dube uses Excel to show the basics of relational databases. • which is a high-level overview of Access and the components that comprise an Access database. • takes a look at creating your first database and tables to store your structured data. • looks at the means to return specific portions of the data stored in the database tables.

Having a basic understanding of the concepts provided in these articles will make the following a bit easier to digest. Database Relations and Normalization Imagine you are running a company selling 50 different types of widgets all over the world. You have a client base of 1,250 and in an average month sell 10,000 widgets to these clients. You are currently using a single spreadsheet to track all of these sales – effectively a single database table.

And every year adds thousands of rows to your spreadsheet. The above images are part of the order tracking spreadsheet you are using.

Now say both of these clients buy widgets from you several times a year so you have far more rows for both of them. If Joan Smith marries Ted Baines and takes his surname, every single row that contains her name now needs to be changed. The problem is compounded if you happen to have two different clients with the name ‘Joan Smith’. It has just become much harder to keep your sales data consistent due to a fairly common event. By using a database and normalizing the data, we can separate out items into multiple tables such as inventory, clients, and orders. Just looking at the client portion of our example, we would remove the columns for Client Name and Client Address and put them into a new table. In the image above, I have also broken things out better for more granular access to the data.
