You're comparing apples and oranges here. RDP and RDi are products. You either can or could purchase them. They have part numbers. Other products include WDSC, RBD, RAD and RTC.

Meanwhile RSE is a perspective. It's not a product, you can't buy it. You only get it as part of something else.

This goes back to the early days of Eclipse. Eclipse is designed to allow developers to create views and perspectives, which are tools that let people do their jobs. Meanwhile Eclipse allows marketers to bundle those tools together in ways that make sense to sell them, and that becomes a product.

Us green screen dinosaurs are used to buying AS/400 tools as standalone, dedicated products. It's a tool, it works on the AS/400, and that's all it does. SEU, SDA, DFU. Because of that, we tend to think of RSE as an AS/400 tool, and sometimes we talk about it as a standalone tool, but it's not. It's just one small part of a tool suite which we can configure however we want. (And yes, I used AS/400 intentionally <grin>).

Specifically in this case, RSE was one perspective that was included in WDSC, RDi and now in one of the features of RDP. WDSC and RDi were both midrange-oriented bundled products. But IBM and more specifically Rational moved away from that, and continued to unbundle things. Now the only bundles they offer are "soft bundles" which are combinations of existing products.

RDP is the logical evolution of the unbundling process: the base RDP doesn't have platform-specific features, it's the base on which platform-specific features can be combined. Get just the RPG tools and you have the equivalent of RDi. Add in RBD and you have RDi-SOA. Take RDi and add RAD and you have what was originally included in WDSC. In all of these cases, RSE is still just one small part of the whole thing.

Even in RDi, RSE is not the entire product. RSE is not very useful without the debugging perspective, as one example. And of course the fact that you can use RDi to write Java applications is a very important feature, at least for those of us who like Java. :)

Anyway, long answer for a short question. I just wanted to point out that RSE is not a product, it's just a feature. RDP and RDi are like iPad and iPad2; RSE is like the GPS. It's part of both, but not a standalone product.


Is the RSE PC Software client just an older version of RDP, which is an older version of RDi (Rational Developer for i) ?
