If you're getting heavy-duty with the math in a script, you may need to take advantage of some of VBScript's advanced math functions These include Atn(): Arctangent Cos(): Cosine Sin(): Sine Tan(): Tangent Log(): Logarithm Sqr(): Square root Exp(): Returns e (the base of natural logarithm) raised to a power Randomize: Randomizes the system's random number generator Rnd(): Generates a random number This random number business in particular deserves some explanation, because you may think that'd be a much better way to come up with values for a password It can be, provided you thoroughly understand how randomness works inside a computer First, never forget that computers are giant calculating devices There's nothing remotely random about anything that goes on inside a computer As a result, no computer can generate a truly random number without special hardware that's designed to do so The Rnd() function returns a value less than 1, but greater than or equal to zero You can pass a parameter to Rnd() to control its behavior A number less than zero, such as Rnd(-2), will return the exact same number every time, using the number you supply as the seed This isn't random at all A number greater than zero, such as Rnd(2), will return the next "random" number in the computer's sequence Zero, or Rnd(0), will return the most recently generated random number again and again VBScript's random number generator uses a seed as its initial value, and then calculates pseudorandom numbers

This allows your customer service employees to see the data they are meant to see In addition, what if you need to add a sensitive piece of information to a table that not everyone needs to see For example, suppose you need to start storing all your customers social security numbers; you add a new column to tbl_customer called SSN Any users who currently have read access to the table can now see this new SSN column, whether or not you want them to have that access Extra steps need to be taken to prevent them from seeing the new data But when you use an abstraction layer, this problem ceases to exist Adding a column to a table does not automatically add it to your view, provided you didn t create your view using the SELECT * syntax Now the extra steps would be required to expose the data, and not to hide it To expose the information, you would need to modify any views you want this new column to appear in, or create new views

Boolean math is a special kind of logical math If you know how to subnet TCP/IP addresses, you already know Boolean math, although you may not realize it First, here are the basic Boolean operators that VBScript supports: NOT: Reverses a value from 0 to 1 (or False to True) or vice versa AND: Returns a True if both values are True OR: Returns a True if either value is True XOR: Returns a True if one, but not both, values are True In VBScript, the value zero represents False; all other values represent True Internally, VBScript generally uses -1 to represent True To demonstrate Boolean math, try the following examples:

The Display class provides methods to query the color capability of the client device The methods isColor, numColors, and numAlphaLevels provide information about whether the device has a color or monochrome display, the number of colors (or gray levels), and the number of supported alpha-channel levels in off-screen images, respectively

Extensibility refers to the ease with which you can modify your data model as your future needs change By change, we mean adding columns to hold new pieces of information, modifying existing columns to change the way data is stored, or even adding or removing whole tables It s hard to predict what our future needs will be, so it is our job to make the database as extensible as possible so that we can react to future needs as they arise We also want our models to be flexible Although it s similar to extensibility, flexibility refers to how much of your model you can change without causing significant or any impact It is true that flexible models will likely also be extensible, but this isn t always the case In either event, an abstraction layer is your best friend when it comes to extensibility Your abstraction layer allows you to make almost any change you can imagine to the physical tables and not affect a single piece of application code If all your applications and users are reading data from views and manipulating data using stored procedures, you simply need to update these items as appropriate to prevent problems How many times have you wanted to make a change to a database, such as splitting one table into two tables, but have not been able to because it would require code to be reviewed, changed, and recompiled We have been in this boat more times than we care to remember The problem stems from the lack of an ab-
