So what determines whether two sets of rows can be compared using the set operations union, intersection, and difference Formally, the two sets must have the same number of columns, and each column must have the same domain Strictly speaking, a domain is a set of possible values However, in practice, the requirement for set operations is that the corresponding columns in each set of rows have the same types both character, both integer, and so on The names of the columns do not need to be the same Sets or tables that meet these requirements are referred to as being union compatible, although the requirement is necessary for the intersection and difference operations as well Figure 7-4 shows pairs of membership tables from different clubs The two tables on the left are union compatible. vb.net code 39 reader VB .

NET Code 39 barcode Reader Control is an advanced developer-library for . NET class ... NET Code 39 barcode scanner can read barcode images using VB . Having a simplified interface means that we could have all kinds of behavior happening behind the function calls to turn and move, but the caller can ignore all those details and concentrate on using the car instead of managing the car. As long as the method signatures don t change, the caller really doesn t need to care about any of that. Let s extend the class definition now to add persistence so we can save and load the car s state to disk. The goal here is to add it without breaking the existing interface to our class. First, pull in the pickle module. Pickle will let us convert Jython objects into byte strings that can be restored to full objects later. vb.net code 39 reader C# .

Even though the names of the columns are different, they have the same number of columns, and corresponding columns have the same types The two tables on the right are not union compatible Even though they have columns with the same names, the order is such that the fourth column has a character type in the top table and a number type in the bottom, and vice versa for the last column Different implementations of SQL may interpret the strictness of this sameness of domains or types differently Strictly speaking, two fields defined as CHAR(10) and CHAR(12) have different domains, but many implementations of SQL will allow these to be regarded as the same for the purposes of set operations Some implementations will also convert numbers into characters to enable set operations to be carried out. The dvdList.aspx page applies the transformation. This is a simple page written in VB .NET: <%@ Page Language="VB" %> <%@ Import Namespace="System.Xml" %> <html> <head> <title>DVD List</title> <link href="styles.css" type="text/css" rel="stylesheet" /> </head> <body> <h1>DVD Library</h1> <form runat=server> <asp:Xml id="dvdXML" DocumentSource="dvd.xml" TransformSource="dvdDetails.xsl" runat="server" /> </form> </body> </html> The code starts by declaring the page language and importing the System.Xml namespace: <%@ Page Language="VB" %> <%@ Import Namespace="System.Xml" %> Then it includes some XHTML tags to create the page and display a header: <html> <head> <title>DVD List</title> <link href="styles.css" type="text/css" rel="stylesheet" /> </head> <body> <h1>DVD Library</h1> Now, just add two new methods to load and save the state of the object. Listing 6-3. def save(self, filename): state = (self.direction, self.x, self.y) pickle.dump(state, open(filename,'wb')) def load(self, filename): state = pickle.load(open(filename,'rb')) (self.direction, self.x, self.y) = state Simply add calls to save() at the end of the turn and move methods and the object will automatically save all the relevant internal values to disk. There s a slight problem here: we need to have different files for each of our cars; our load and save methods have explicit filename arguments but our objects themselves don t have any notion of a name. Let s modify the intializer so that we always have a name bound into the object. Change __init__ to accept a name argument. Listing 6-4. def __init__(self, name, x=0, y=0): self.name = name self.x = x self.y = y self.direction = self.NORTH People who use the Car object don t even need to know that it s saving to disk, because the car object handles it behind the scenes. Listing 6-5. def turn_right(self): self.direction += 1 self.direction = self.direction % 4 self.save(self.name) def turn_left(self): self.direction -= 1 vb.net code 39 reader Visual Studio .
