Takeaway: Even
as new tech drives IT forward, certain systems and languages keep the
past alive. Here are 10 technologies that will be with us for a while.
The world of software development has a strange
irony to it. On the one hand, technology is changing so quickly that
developers are forced to constantly learn new tricks to stay current. On
the other hand, existing projects and code are so hard to replace,
systems can stay in maintenance mode for decades, slowly being
significantly rewritten but never actually replaced. These 10
technologies are ones that software developers will be using for a long,
long time, even if some are past their heyday.
1: COBOL
COBOL is all over the place and probably always will be. There are
millions of lines of COBOL code out there powering banks and insurance
companies and other mission-critical systems that handle massive amounts
of data. Many of these systems will be in services for decades if not
centuries without replacement.
2: VBA
A lot of systems that use VBA, VBScript, or VB6 (all related
technologies) are outdated. But VBA is still the macro language for
Microsoft Office, and plenty of people depend upon it to do their jobs.
As miserable as it is to work in VBA (it has collections but does not
allow you to check if a value exists in them?), it will be around for
quite a while unless Microsoft somehow comes up with a suitable
alternative.
3: .NET WinForms
When Microsoft came out with .NET, developers used WinForms to make
Windows applications with it. WinForms was a thin veneer on top of the
Win32 API, and for VB6 and MFC developers, it felt very comfortable. For
better or worse, Microsoft is replacing WinForms with XAML; first in
Silverlight and WPF, and now with Metro. All the same, the fast rise of
.NET meant that tons of WinForms applications were built — and they will
be maintained for a long time, just like the VB6 applications out
there.
4: Flash
A few short years ago, it was impossible to even imagine a Web
without Flash. It was everywhere. While Flash still is everywhere, HTML5
threatens to push it out of its spot for rich Web development. Even so,
there will be existing Flash work out there for ages, and it will be
maintained and extended. HTML5 still can’t replace Flash for some
things, either.
5: C
Until fairly recently, C was enjoying a graceful, slow drift away
from actual application development and being relegated to the roles of
hardware driver and operating system development. And then the iPhone
(and later, iPad) were released, causing a massive surge in use of
Objective-C, which is a superset of C. Now, thousands upon thousands of
developers have learned C in the last few years and used it to write
hundreds of thousands of cutting-edge applications. Talk about a
comeback! The popularity of iOS will ensure that C will be used for
application development for some time to come.
6: FORTRAN
If languages were people, FORTRAN would be regarded as COBOL’s fuddy-duddy spinster aunt. But like COBOL, FORTRAN was
the
language of choice for certain industries and sectors, a pile of code
got written in it, and replacing that code is basically impossible.
Where COBOL runs the banks, FORTRAN runs things like weather prediction.
7: SQL
SQL is a strange case. On the one hand, databases that use SQL are
still all over the place, and SQL is often the only way to work with
them. So it is no surprise that the SQL language itself is out there in
spades. What
is a surprise is how many developers are still
writing a lot of SQL code. With all the various database abstraction
systems out there, such as the ORMs (Hibernate, Entity Framework, etc.)
and other systems (Active Records, LINQ), why in the world does anyone
actually write SQL into their applications? It should be the (very rare)
exception, not the norm, yet many developers find a need to write SQL.
Even if everyone stopped writing SQL by hand tomorrow, though, systems
would be automatically generating it anyway.
8: ASP.NET WebForms
When ASP.NET was first released, WebForms had the unenviable task of
trying to make Web development feel as familiar as possible to
traditional desktop application developers. To make it even more of a
challenge, it carried over and extended many of the technologies from
Classic ASP, while completely changing the overall model. WebForms
clearly suffered from serving too many masters, and less than 10 years
later, Microsoft was pushing ASP.NET MVC’s streamlined model in its
place. Like WinForms, the WebForms’ similarities to previous systems led
to rapid adoption, so WebForms Web applications will be around for
quite some time.
9: Java
Java is nowhere near being close to a decline. It is still a strong,
vibrant ecosystem. But if and when the day comes that people start
referring to it as “legacy,” it still will have many, many years left.
It is no surprise that Java is often called “the modern day COBOL” by
industry observers. It has a combination of traits (like running on *Nix
servers and mainframes) that makes it attractive to the same industries
that COBOL appeals to. Java has made impressive inroads into those
areas, and even if the flashier uses of Java (like Web development) go
away, it will still hold a prime spot in the world of Big Iron.
10: HTML
It is hard to believe, but at one point, the Web was little more than
a way of posting documents online so that you could easily access one
document from another. About 20 years later, and HTML is now a wildly
popular development system that has enabled an unimaginable revolution
in how computers are used. And the funny thing is, up until HTML5, it
was never deliberately designed to fulfill the role it was filling. It
is hard to imagine a computing world without HTML (or one of its
descendants) in the future.
