Trends: REST to over take SOAP?
Not too long ago I took a class for developing web services. The content of the class focused almost exclusively on developing SOAP based web services. While there is nothing particularly difficult about SOAP, it seemed to require a lot of steps; defining your data elements, creating a wsdl, and all the tools you had to use. While having a contract can be beneficial when the web service will be facing external clients, it seemed to be a lot of steps to go through to get a web service going and also heavy-weight.
Trends: Should developers know SQL?
I recently have been involved in a lot of refactoring work at my company. One issue we ran into was our usage of SQL in our applications, we had a habit of including a lot of business logic in SQL. To make the applications more maintainable we moved a lot of our business logic from SQL to Java. While I believe we made the right decision to remove the business logic from SQL I don't think it would be in all scenarios.
Trends: Getters and Setters, going the way of the dinosaur?
Like all developers I was always taught to use getter and setters to access the internal members of an external class, and up until recently I accepted this idiom blindly. Not too long ago I was on a discussion board when a young developer asked what the getters and setters were doing in a snippet of code.
