Address validation using Google Maps API

阅读更多关于 Address validation using Google Maps API

I have a task to validate addresses entered into a system I am currently creating. The system requires that address entered are validated against a valid data source. In the UK the dataset comes from the Royal Mail and is expensive to access. The data needed is post code info for the whole of europe to start with accessed by an API into the web application. There are a number of companies that offer this service, QAS Capscan Postcode anywhere These all offer the service I require. However this is expensive and in some cases not a complete data set. e.g. not Ireland I was also wondering if

问题 From first glance, it would appear I have two basic choices for storing ZIP codes in a database table: Text (probably most common), i.e. char(5) or varchar(9) to support +4 extension Numeric, i.e. 32-bit integer Both would satisfy the requirements of the data, if we assume that there are no international concerns. In the past we've generally just gone the text route, but I was wondering if anyone does the opposite? Just from brief comparison it looks like the integer method has two clear

阅读更多关于 Best practices for storing postal addresses in a database (RDBMS)?

Are there any good references for best practices for storing postal addresses in an RDBMS? It seems there are lots of tradeoffs that can be made and lots of pros and cons to each to be evaluated -- surely this has been done time and time again? Maybe someone has at least written done some lessons learned somewhere? Examples of the tradeoffs I am talking about are storing the zipcode as an integer vs a char field, should house number be stored as a separate field or part of address line 1, should suite/apartment/etc numbers be normalized or just stored as a chunk of text in address line 2, how

What is the ultimate postal code and zip regex?

阅读更多关于 What is the ultimate postal code and zip regex?

问题 I\'m looking for the ultimate postal code and zip code regex. I\'m looking for something that will cover most (hopefully all) of the world. 回答1: There is none. Postal/zip codes around the world don't follow a common pattern. In some countries they are made up by numbers, in others they can be combinations of numbers an letters, some can contain spaces, others dots, the number of characters can vary from two to at least six... What you could do (theoretically) is create a seperate regex for

问题 I\'m after a regex that will validate a full complex UK postcode only within an input string. All of the uncommon postcode forms must be covered as well as the usual.

There is a brief description about the data and the attached
