Microsoft Excel is a phenomenally powerful calculator. You can create spreadsheets with 10,000 lines of data and calculate subtotals instantly. Indeed, if you change your data, any totals will get automatically updated. Arguably that‘s not too impressive. If we have quarterly revenues of \$1m, and we secure another \$20k, we can update our subtotal without summing revenues from scratch. So it‘s more impressive that Excel can do the same thing with statistical functions. If you‘ve ever plotted a chart on Excel, you may be aware that you can add a best fit line. These best fit lines are calculated using a method known as regression. Basically, you have to calculate the distance of every single point from the line, and minimise the sum. The maths is a little more sophisticated but the key point is that, every time you change the data, you need to perform the analysis all over again.

Structured Query Language, often referred to as SQL, is a grammar of instructions that allows us to tell a relational database to add, modify or delete data. The key benefit, pardon the pun, of SQL is that it allows us to craft instructions relating large sets of data together. In this way SQL is the natural complement to the single cell and formula based interface of spreadsheets like Microsoft Excel. Imagine you had five hundred appointments from your business calendar laid out in a table. Each appointment might have a day, time, location and description. Now imagine you also had five hundred appointments from your partners business calendar, also each having a day, time, location and description.

One of the topics I cover on my Advanced Excel courses is hardly ‘advanced‘ at all, but it is a very useful and popular technique with my students. It makes use of the OLE capability to create invoices by embedding Excel data. First you need to create an Excel spreadsheet and format it in an appropriate manner, keeping in mind that this will form the basic structure of your invoice and will eventually be seen by your clients. You don‘t include any Company contact details or logos in the spreadsheet though as these will be incorporated into the Word document. The next step is to lay out the invoice itself in a Word document, based upon your normal Company letterhead. Leave the main body of the document empty as this is where the Excel spreadsheet will be embedded. All you need in this master Word document is your usual Company branding and contact information.

Additionally, it would prevent pirating software and Microsoft would be able to have a steady stream of income and continually upgrade their software without having to worry about people stealing their software code. Google of course is beta testing their similar project in order to head Microsoft off at the pass and compete with them for the new paradigm of computing on the Internet. If all your data was stored you would never have to worry about your computer crashing because everything is backed up somewhere else and safe.

The former hangs like a transparent curtain four feet above the floor and shrink-wraps itself to anyone bold enough to attempt passing through. The latter represents a fragrant blend of beer, cheap cologne, and unkempt toilets, and assaults an unsuspecting visitor‘s nose like an aggressive index finger. By Saturday, the fragrance would be pungent enough to cause mere mortals to speak in tongues. Lance led the way with Lester in tow, dodging around dark figures that emerged from the nicotine and odoriferous fog. Lester had difficulty keeping up, licking the lenses of his glasses and tie-drying them as they wove their ways toward diffused light they assumed was the bar area where lusty women awaited.

Oh my goodness, it‘s not surprising that so many couples who want to get divorced just stay separated for years. The process is daunting, expensive and, frankly, ridiculous. Basically I had to stop communicating with my husband immediately. Going forward all communication would be between my lawyer and his lawyer. We would turn in all of our financial documents and her paralegals would put them into spreadsheet form and then we would go about dividing everything up. We would have to come up with a parenting plan, my husband and I, with these two lawyers translating for us. We would have to get employment contracts from his employers so I knew that I was getting a fair share of all of his assets. It was going to be long and drawn out and messy. And the cost, somewhere between \$15,000-\$100,000, minimum.
