Great screencast and explanation! Just two questions. Inheriting interfaces would that not be a problem for classes that just needs to implement the query and save data methods? The queryreportdata method would be 'not implemented'. A class implementing an interface such as IDataAccess not violate the SRP? It is both responsible for querying data and saving data? |
Stephen: That's a great point -- my idea for inheriting IDataAccess from IReportDataAcccess was really to demonstrate that its possible to inherit Interfaces in the same way that people typically look at inheriting classes and that this represents a feasible way to both decompose FAT interfaces into smaller, more focused interfaces and at the same time ensure reverse-compatibility with any existing code rather than to ensure that the existing 'legacy' interface of IDataAccess adhered to to SRP in all apects of it. But, yes, absolutely a class that implemented the newly-refactored IDataAccess would nearly-certainly be in violation of SRP both in spirit and in practice :) -Steve B. |
Hi. I love this format. Quick and easy. Appreciate the effort. But I thought that ISP was from a consumer POV, not the implementer. That, if a set of components are only consuming a subset of the functions in an interface, then this subset should be its own interface. http://www.objectmentor.com/resources/articles/isp.pdf |

I have been studying English language most of the time. In my search for online tools about English grammar rule, I was brought this this page for unknown reasons. |
However, in view of my Philosophy class. This is also useful |
He might not go this week, but he's further proof sea dweller that being sea dweller adorable can get you into the semifinals but rolex submariner not much rolex submariner further. Urban is the weakest male link, so he might as well blast submariner off with a submariner submariner blaze of glory with something rolex yachtmaster ridiculous like rolex yachtmaster And I Am Telling You I'm Not yachtmaster Going. |
With yachtmaster rolex yacht master Jermaine Sellers rolex yacht master gone, dancer Hall remains as the loose cannon in the yacht master bunch. His yacht master confidence hasn't yet meshed with a breakout performance, and replica watches though his replica watches sedate take on Tina Turner's What's Love Got to Do With replica watch It was replica watch interesting, Hall has been the fake watches judges' punching fake watches bag to date. |
Unless he kills it, say with a seductive Usher throw-down, Hall could be rolex the next to rolex go. Speaking of cute, James is still trying to shake off the whole rolex watch cougar-bait rolex watch thing, but his limp rendition of the too-frequent Idol cover I Don't Want to Be didn't rolex watches exactly show rolex watches off his rock chops. Regardless, assuming he doesn't completely tank, Casey replica rolex will likely make the top 12. He should, however, soar by proving replica rolex his grit this week with something edgier. How about an unplugged rolex replica Kid Rock tune? He's the rolex replica token rocker, which is a good place to be this year, because he's got virtually no competition. |
Dewyze is on a hot streak, and he's got Simon tissot on his tissot side, so he should play it safe this armani watch week to ensure armani watch a top 12 berth. He's done well playing his acoustic armani watches guitar, so armani watches maybe a Kings of Leon song would work for him. What armani happened armani to you, man? Garcia seemed a shoo-in for audemars piguet watch the top audemars piguet watch three. |
But he's gotten steadily diminishing returns thanks audemars piguet watches to sleepy audemars piguet watches song choices, like James Morrison's You Give Me Something, which audemars piguet find him audemars piguet fading into the pack. He needs another Straight Up, pronto! Now's lv watch the best lv watch time to wow the judges again with a clever arrangement lv watches of a classic lv watches — perhaps a folky version of Jane's Addiction's Been lv Caught lv Stealing? |
He's not blowing anyone away, but movado watch slow-and-steady movado watch Lynche is getting it done every week. He's likeable, solid and very comfortable onstage. Big movado watches Mike is almost movado watches certainly going to advance, so a bit more of what the movado judges already movado like, perhaps a touch of Maxwell on parmigiani watch acoustic guitar, could parmigiani watch ensure his spot. Either Lambert is pulling a rope-a-dope and is planning to emerge parmigiani watches as a camera-ready parmigiani watches superstar from his mullet-duckling persona, or we're reading too much into his phoenix-like rise from the ashes of two twitchy weeks ago. |
