The Importance of API “Transports”

SQL Databases are dead

There I said it. I jumped the NoSQL waggon and I refuse to use anything that is remotely uncool and old.

Of course the above is a lie. Well kind of. In reality I do think that the interface by which you communicate with a SQL database is dead (or rather should be, but so should FTP -- another story -- still there are a few people left using it).

I’m not really talking about the query language itself, I’m talking about the “transport” (lacking a better word).

So is (nearly) any other protocol

I’ll leave the kool new aid road now and talk about the transport stuff a bit.

My problem with API interfaces currently is that the usage of these interfaces is quite annoying. Let’s look at the products that people use all over the web.

Say you go to Facebook or Google and what to use their API to do something with the social networks represented by the data. On the API page of Facebook you’ll find some source package that implements a transport protocol, a domain specific language and to complicate things a bit further also a certain data representation.

Reality is that right now to use some service on the Internet there is only a single transport protocol. HTTP, maybe add SSL on top of that but the transport is HTTP. I’m not saying that the HTTP protocol is the ultimate protocol. It’s shortcomings are quite well known.

The point is that you can solve a whole set of problems all in one go and be done with it.

Back to the SQL Example

So you have this cool new project and decided to use some relational database system. Now you also decide to use a framework that relies on interactions with other systems being non-blocking. So you run around the web and look for some non-blocking driver for you RDBMS of choice.

Then you run around the web and look for some non-blocking driver for you storage part, then you run around the web...(you get the idea).

Now if all your satellite systems would be exposed oder HTTP you’ around the web and look for a non-blocking HTTP client and be done with this category of problems.

Just don’t use HTTP...please!

Please, please, please...don’t just use HTTP because I used it as an example here. A unified (or generalized) transport really needs some serious thinking.

Of course you can just run away now and scream what kind of idiot I am, but the next time you run around the web and and look for a driver because the transport of services isn’t generalized enough to be reusable.

Also please don’t confuse the transport with the represenation -- which should be considered equally important and would solve another stack of problems.

And if you go that last route, that still doesn’t say that should be only a single language per domain, having a single language per domain would be not that good without wasting further thoughts about those last two statements.
