Sql Index

Indexes help us retrieve data from tables quicker. Let's use an example to illustrate this point: Say we are interested in reading about how to grow peppers in a gardening book. Instead of reading the book from the beginning until we find a section on peppers, it is much quicker for us to go to the index section at the end of the book, locate which pages contain information on peppers, and then go to these pages directly. Going to the index first saves us time and is by far a more efficient method for locating the information we need. The same principle applies for retrieving data from a database table. Without an index, the database system reads through the entire table (this process is called a 'table scan') to locate the desired information. With the proper index in place, the database system can then first go through the index to find out where to retrieve the data, and then go to these locations directly to get the needed data. This is much faster. ...

Soundex Limitations

Names that sound alike do not always have the same soundex code. For example, Lee (L000) and Leigh (L200) are pronounced identically, but have different soundex codes because the silent g in Leigh is given a code. Names that sound alike but start with a different first letter will always have a different soundex code. Thus, names such as Carr (C600) and Karr (K600) have different soundex codes even though they sound alike. Name that sound alike but have different first letters should have each name calculated and searched for separately. Since the soundex system is based on English pronunciationn, some European names may not soundex correctly. For example, some French surnames with silent last letters will not code according to pronunciation. An example is the French name such as Beaux - where the x is silent. While Beau (B000) is pronounced identically to Beaux (B200), they will have different soundex codes. This could be true of any surname that does no...
