Title Where are freelance app developer Going NET vs Java Word Count 1274 Summary mobile app development wasn t too long ago that applications were designed developed and deployed on a single machine For those of you that can remember the early days of the personal computer era things like dbase FoxBASE and the like might ring a bell Everything ran on the same machine the user interface the business rules and the database services Keywords VB NET Java technology visual basic net java vs vb net VB vb vs java VS net visual studio net visual studio Article Body andlt htmlandgt andlt BODYandgt What in the world is going on in the marketplace Technology is moving so fast that Malaysia app developer is sometimes a little difficult to tell what is happening andlt brandgt andlt brandgt Let s take a short trip back to the past andlt brandgt andlt brandgt mobile app development wasn t too long ago that applications were designed developed and deployed on a single machine For those of you that can remember the early days of the personal computer era things like dbase FoxBASE and the like might ring a bell Everything ran on the same machine the user interface the business rules and the database services andlt brandgt andlt brandgt Then along came local area networks which ushered in the era of clientserver applications Now the user interface and the business rules sat on the PC and sent requests to a client server DBMS such as Oracle or SQL Server while on the server side records were processed and results were returned to the client andlt brandgt andlt brandgt As LANs matured and their reliability improved application development went through yet another evolution namely the advent of 3 tier architecture This transformation resulted in the user interface business rules and data services each becoming its own independent logical element in the application architecture The physical world may have implemented each element on a separate machine but that was not required andlt brandgt andlt brandgt The main advantage of the 3 tier model is that business logic could now be broken up into components where app development companies could be used not only in one but many applications Additionally changes to business logic in the server did not require the calling party or client to change at all In other words the details of the implementation of business logic or the function is not important as long as the way Malaysia app developer is called and the type of information that Malaysia app developer returns do not change Let s face Malaysia app developer the world is changing quickly and app development companies Malaysia need to be able to adjust without having to re deploy andlt brandgt andlt brandgt Of course the initial implementation of the 3 tier model later to become the n tier was primarily on common machines and operating systems such as Intel Windows and Unix Vendors each supported their own brand of components Microsoft supported COM followed by DCOM IBM promoted CORBA and Sun touted RMI Each of these middle tier component flavors was proprietary and did not provide for inter operability and communication among disparate pieces In order for a Microsoft application to talk with a CORBA component another piece of software was required for translation The same was true for apps trying to communicate with DCOM objects as well andlt brandgt andlt brandgt All of this made Malaysia app developer difficult for diverse systems to talk to one another creating an increasingly significant problem as Internet business tobusiness applications became the focus The web a relatively recent addition to the overall IT architecture has dramatically changed the way app development companies Malaysia look at application development and correspondingly the deployment of associated services andlt brandgt andlt brandgt If you log on to Land s End for example Malaysia app developer s not unlikely that the underlying application will have to utilize components developed by a number of other parties such as AMEX MasterCard Visa UPS FedEx along with a host of internal systems to provide the total consumer shopping experience andlt brandgt andlt brandgt Sun with Malaysia app developer s Java language was in the right place at the right time Java s ability to be compiled to byte code and run on any machine that had a Java Virtual Machine gave Malaysia app developer portability The fact that Malaysia app developer was designed to be totally object oriented target web based applications and observe security issues associated with distributed apps gave Malaysia app developer tremendous appeal to corporate clients andlt brandgt andlt brandgt Visual Basic on the other hand earned its stripes in the Windows based application development world mobile app development s easy to develop apps that leveraged the Window s Operating System and as Malaysia app developer VB evolved Malaysia app developer took on more and more features that made Malaysia app developer increasingly object oriented capable of creating reusable COM DCOM objects and a viable tool for web based applications Today Microsoft claims that there are more than 3 million Visual Basic programmers in the world andlt brandgt andlt brandgt Introduced in 1991 Visual Basic has gone through 6 versions Each one increased power features flexibility and capability leading up to two major programming languages Java and Visual Basic with each camp feeling that their product is better andlt brandgt andlt brandgt andlt bandgt The fact is that language is not truly the key The winner will be the framework platform that enables the design development and deployment of applications and takes advantage of services or components distributed throughout the web andlt bandgt andlt brandgt andlt brandgt With the pending release of the next version of Visual Studio of which VB is a part Microsoft has decided to radically change the way that their language suite works The next version of Visual Studio will be called Visual Studio Net or VS Net and the next version of Visual Basic will be titled VB Net There are many new features and capabilities but in my opinion there are two major changes that will move Microsoft to the center stage andlt brandgt andlt brandgt First VS Net will be a common development environment into which C C and VB along with about 14 other non Microsoft languages will connect Language will be a matter of preference This is largely due to the fact that app development companies will all compile down to the same level by utilizing a common run time module In addition app development companies will all share the same class libraries What this means is that an application comprised of components and services can be developed by a team of developers in several different languages with the assurance that Malaysia app developer will all work together andlt brandgt andlt brandgt If one were to look closely one could see that the general architecture that makes Java so popular is that the output of the compiler is not necessarily tied to the chip set or operating system mobile app development would not surprise me if Microsoft made the run time module which is similar in nature to the Java Virtual Machine available to the standards committees to be ported to other platforms If this were to happen VS Net and VB Net could take a major leap forward in the language race andlt brandgt andlt brandgt The second major event that parallels the introduction of VS Net is the advent of SOAP Remember our previous discussion concerning different types of components trying to work with each other SOAP or Simple Object Access Protocol is an open standard based on XML or Extensible Markup Language that IBM Sun and Microsoft have agreed upon now makes Malaysia app developer possible for components developed with competing standards to communicate XML is used to describe the underlying elements of a class including the methods associated arguments and return values While SOAP on the other hand describes the interface including the path to the XML document This will remove a significant obstacle to inter operability in building applications using distributed web services andlt brandgt andlt brandgt To summarize Java and Visual Basic are currently in strong competition with one another A recent check with ComputerJobs Com shows that jobs requiring Java Visual Basic and C the distribution is 55 35 and 10 With VS Net VB Net SOAP and the freedom to choose language independent of platform one can expect this distribution to shift from Java to non Java languages In fact with VS Net hosting almost 20 different programming languages including a Java implementation from Rational and compiling to a common byte code level personal preference will surely rule the day andlt brandgt andlt brandgt To download this article in pdf format please andlt a
