So now that we have understood what the main questions, what the main concerns are when we do an architecture, we go into these things that have called architectural patterns or styles. It's used interchangeably, so you can say either architectural styles is maybe more common. And what they are, is essentially good practice. So it's some kind of practice that has been used in different contexts. We know that it works in certain ways. We know what the trade-offs are. For example, if it gives us more performance or more security, we of course also know what the disadvantages are, but essentially it's a record of what is good practice. And we go into five of them and the first one we look into is called the model view controller style, which you have probably already heard of. And as the name says, we have three elements. We have the controller. We have the model. We have the view. So this is the model view controller or MVC pattern. There are variants of this nowadays. This one has a couple of disadvantages, but it has evolved a bit. So you might hear other things like MVVP or so, but they are related at least. Now, what we do in the model view controller is essentially we try to have the data, the state of our data, which is here in the model, independent from the view of the representation of it and the way we control it as well. So for example, you might have a certain data here. I mentioned the web shop earlier. So you might have a shop where you buy different things. And you could have a website for that, but you could also have a mobile application. And depending on which one you use, you might have different views. It might look differently. And this means you don't have to somehow copy everything, but as a central, for example, one or many databases where the data, the actual state of your shop is, but you have multiple of these views and you can later on add a new one or remove it. So this is very flexible in the sense that the data stays the same, but you can evolve the rest independently. And essentially, you have the data. The view queries it. So it somehow gets the data from a database, for example, and represented in a certain way, for example, a table on a website. The model, if something changes in the data, might also notify the view. So say, listen, my data has changed. Please reload the website, for example. The view is often an event-based thing. So there might be a user event, like a user is buying something. And the view that informs the controller is something that happened. And depending on what has happened, the controller updates the model. So this is usually how it is. The controller might, of course, also trigger an update in the view itself without changing the data. So in general, this is a very common pattern. For example, for websites, for mobile applications, this is extremely common to do. And the advantage here is exactly this separation that you can have the data very differently from how it is represented to the user. And that's not only useful if you have multiple views, like the mobile client and the web client. It's also useful if, for example, the view is developed by a different organization. So you don't really have control over this. Or when you design the model and the controller, you don't really know yet how this will look like. So it might change later. So that's why the Model View Controller is a very nice pattern for this case. Good. So much for MVC. I just wanted to mention it shortly, since many people might have already seen this. The next one we'll go into is another very popular one, it's the layered architecture.

I was a Wally yesterday I was terrible and tomorrow is going to be a better day so I'm going to vlog tomorrow I'm going to tell you all about it I'm going to tell you how amazing my day is going to be and how much knowledge I'm going to bring to that ward because I feel like I've got so much more to bring to this ward and bring out the best in myself and let them see that because yesterday was a let down I'm very disappointed in myself so tomorrow I'm going to bring it I'm going to hopefully have an amazing day and just really redeem myself this is day two of my placement I have just parked in the most dodgy place ever because my usual space was taken which is very bizarre because the spot I always have is always free so I've parked down this road it's a little bit dodgy I don't feel comfortable leaving my car there mainly because the back end of it is just touching double yellow lines um I'm hoping no one's going to check and I'm not going to get a ticket for that fingers crossed but yes I am early it's quarter past six I'm looking forward to hopefully redeeming myself today so yeah so let's go smash today and let's redeem myself so that's it I'm home it's like half past nine now you'll have to excuse this because I had to take my hair out because it was just really hurting my head um so I'm back a little bit later because my fob watch decided to stop the batteries ran out and we had a patient that was on literally five minute obs so it was really hard to try and look at the clock on the walls and try and calculate the respiratory rate so I've had to go to Sainsbury's I've got my new fob watch which is working it's the exact same one as I had before it's working so I'm going to use that tomorrow so today has been a little bit better I've slightly redeemed myself because I pretty much saved a life may as well have so what happened I can't go into too much detail because of confidentiality but basically if anybody knows much about morphine morphine has the risk of giving you respiratory depression so if a patient is on morphine you have to give two litres of oxygen and monitor the observation a little bit closely because if they go into respiratory depression they can pass away so we don't want that so we had a patient that was on morphine and I did our observations and a respiratory rate was really low and I was like oh that's not good so I went and I got my mentor and I just said this patient's respiratory rates really low it's such and such what do we do basically because I've never had this happen to me before so I was like what do I do so she monitored it again and the respiratory rate was going down down like really critically low and I was just like oh my god so there's something called naloxone which is a reversal drug which is a reversal drug of morphine basically so if somebody overdoses on a drug if somebody has really bad side effects like this and goes into respiratory depression this drug is given to reverse it basically and bring the patient back now I've been taught this drug in university and we've been told about this drug but I've never seen this drug in action so today literally when when my mentor and another nurse gave this reversal drug it literally worked less than a minute it must have been about 30 seconds because I mean my patient was like she was really drowsy she was almost unconscious she wasn't responding and as soon as they gave it she was like hello I was like oh my god that is fast acting oh my god so I've never seen that before so that was I mean it wasn't good for the patient but for me and learning from that just because we've had the theory behind it and then to see it in practice was actually amazing but what I didn't know was after you've given the reversal drug then you have to monitor the patient every five minutes because the the effects of morphine outweighs the drug the reversal drug so basically morphine is a longer acting and naproxone is literally just a fast acting so you have to keep monitoring for respiratory depression because she can go back into respiratory depression even though you've given the reversal drug does that make sense um am I speaking too fast it's really late so basically I had to keep an eye on these observations I'm hoping that she's going to be okay tonight because I just I don't know what's going to happen um I've never seen this happen and it does make you worry and you sort of worry about your patient when you're home so I'm hoping when I get there tomorrow morning again she's going to be all right and that she's going to be a lot better so fingers crossed all in all it's been a really good day to be honest it's been all right it's been absolutely manic I've been rushed up my feet I'm really tired I'm going to now shower because oh my god let me tell you this let me tell you this so the reason why I have to shower is one I smell but two I was dealing with a patient in the morning and how do I say this in a polite way so basically she leaked feces onto my trousers and down my leg so I was there and I was like oh what is she just doing so in my head I was like oh my god on the outside I was like okay let's just sit you in the chair get you sorted blah blah so I helped the patient first obviously and then afterwards I had to go and wash my leg I had to wash my trousers down um I washed it with soap and then I washed it with hand gel anything that I could possibly think of it went on my trousers so that was a little bit awkward and this is what you're going to have to deal with guys if you've not done wards before you're going to have to deal with feces you're going to have to deal with urine you're going to have to deal with blood vomit sputum you name it you're going to get it on your uniform you're going to get it on your shoes so make sure your shoes are leather and they are wipeable top tip there you go so yes so I got feces on me I literally had a poo day so I'm going to go shower and scrub my body now this uniform is going on a boil wash and hopefully tomorrow's going to be another great day for learning I'm hoping my patient's going to be okay I also find out that we because I'm coming to the end of year two going into the year three I can be trained to do the blood glucose monitoring the finger brick so tomorrow there is a training session on that so I'm going to go over to that and experience that so that'll be really good it's really nice to do training and do a little bit extra on the wards I find like I like to do more and get those skills in where I can so tomorrow should be a really good day I'll update you how my day goes and then after tomorrow I've got three days off I know although technically I've only got one day off I've got Friday off then Saturday I'm at the uni for open day I'm going to work and then Sunday I'm climbing Snowden if you don't already know I am climbing Snowden so I'm going to vlog this I'm climbing Snowden for charity it's for the Cavaltrust charity I'm going to put the links below and the Cavaltrust are an amazing charity that raise money to help healthcare professionals in financial difficulty so they're an amazing charity and I'm obviously raising money for you so I'm going to put the link below if anyone has any spare change or pennies anything you've got wants to donate for this amazing charity I'm going to leave the link below to the just given page this is a practice run just to make sure that we're all okay going up Snowden and then the real run is the 13th of October so you've all got that to look forward to I'm going to vlog about it if I can I'm probably going to be dying up Snowden not going to lie I'm really unfit so that being experience so I'll see you all tomorrow because as always I've raffertyd on about nothing so I'll see you tomorrow and good night for now it's so early I'm awake but it's the last day of my last placement for week one and I've got to get free today and then I've got three days off c'mon let's remind myself this so I'm awake I've just had a wash I've done my face I need to do this hair I don't even know if I'm ready for today and I've arrived so I've just put my badges on I've filled my pockets up what do I have in my pockets actually so I keep a notepad and a pen in my pocket and the handover sheet in my pocket so yeah so hopefully today's going to be good I'm just going to go and make a cup of tea because it's 20 past six I'm 40 minutes early today and yes I'm going to chill out check social media and get started I shall see you all later it's Friday which means I'm off I'm so off it's so lovely but you know what why is it anybody who's in nursing or healthcare profession that knows this that does shift work why do we wake up so early on our days off it's driving me crazy I fully planned to sleep until lunch time today I mean I kind of knew it wouldn't happen but you know I had the hope of sleeping half the day away because I'm so tired I'm exhausted I've had really tough couple of days on the ward and I woke up before seven this morning I think it was about seven woke up because I was desperate for the toilet so I woke up got back into bed hoping to get back to sleep and then I just I was tossing and turning for the next hour so I actually properly come round and open my eyes about a quarter to eight so I suppose that's a lie in considering I've been getting up at half four in the world I'll take it back I'm moaning for nothing that's a lie in so yes today I'm off and I'm just going to talk to you about my day yesterday because I didn't get a chance to vlog by the time I got home I was so tired I had Chinese oh my god it was so good you know I finished my shift and you just by the time I get home it's nine o'clock at night there's literally no chance of cooking at that time at night by the time you've showered got into bed it's 10 o'clock no it's not happening so I went to the Chinese I got some chicken chow mein and some extra bean sprouts because I love bean sprouts so yeah it was amazing it was really good anyway yesterday it was manic it was so so busy and there was nothing in particular that went wrong all of my patients were amazing oh my god so the patient that was telling you about that was really deteriorating was amazing I got in I went over a straight way I checked it and I was like she's awake she's alert she's doing amazing she's eating oh my god fingers crossed when I go back on Monday she's gonna be amazing still let's hope she doesn't deteriorate while I'm not there because I'm just I'm gonna be panicked about this is what happens when you're working the wards you panic about your patients when you're not there so all in all yesterday was a really good day we had three patients being discharged and then we had three new patients come in we had pre-op checklists new risk assessment tools for the patients that have come onto the ward as a nurse or a student nurse if you're working on the ward as soon as you get a patient admitted to you you have to do all of the checks so you'll get this risk assessment book it'll be different across trusts and what they do but for the trust that I work out they have this risk assessment book they have to fill out and it's a few pages long it's all about the nutrition the weight the mobilisation how do they mobilise how are they planning to mobilise it's got manual handling it's got pain assessment it's got skin integrity so you have to do a head to toe assessment of their skin make sure they haven't got any pressure sores or cuts any unexplained wounds blisters moisture lesions all of that jazz obviously with consent of the patient some patients won't let you some patients like not a chance are you looking at my behind so just take that on the chin and don't be offended if they decline and it's their right to decline so that's fine so you just document patient decline skin inspection job done you cover yourself so what else can I tell you about yesterday it was just manic it I was rushed off my feet nothing went wrong so I'm not sure why it was manic but it was I think we were just short staffed on the ward all the wards are short staffed at the minute so you are completely rushed off your feet and you're trying to manage every single patient and do everything for every single patient and it's all at once and it's like ah so it was a bit of a manic day my bones my backs hurting my legs are hurting my feet are hurting my whole body aches today today I'm literally going to spend the day recharging these batteries ready for the weekend because I've got a couple of things planned for the weekend and then back to it on Monday I'm really looking forward to being back on Monday and learning some more so that's it everybody thank you so much for tuning in thanks for watching don't forget to subscribe if you haven't subscribed also if you hit the little bell button you'll get a

incredible and I'm so so excited for this it's the best news I've had all week honest to God so basically for third year at our university we can apply for something called the community rotation program I'm so excited I can't speak and um I got accepted yeah don't know what's wrong with me like I keep crying about things but these are happy tears I'm so chuffed that I've got my community placement I'm so so happy I wanted this so so bad you've got no idea you all saw me on my GP placement so to get the community rotation program for the whole of third year oh my god Birmingham City University you have just made my day this is literally live as it's just happened I've just read the email I had to share the news with you all I'm absolutely chuffed and it's just gonna make the end of second year these last seven weeks on the war just even better I'm so excited I'm gonna go and just chill out now because I've got so excited to make myself cry I'm so sorry I'm such a sap but yeah I'm just yeah see you all next week
