Data has always been Centric to any decision making. Today's world runs completely on data and none of today's organizations would survive a day without bytes and megabytes. There are several roles in the industry today that deals with data and most people have several misconceptions about them. I am Aayushi from Edureka and let me welcome you to this video on the key differences between three of the leading roles in data management, that are data analyst, data engineer and data scientist. So let's move on and see what all we going to cover in this session first and foremost will be starting by getting a quick introduction about the roles as in who is a data analyst, data engineer and a data scientist, then we'll be going through the various skill sets that these professionals possess will also be looking at various roles and responsibilities. And finally, I'll conclude the session by telling you guys this is Leo what a data analyst a data engineer and a data scientist learn so let's begin the session and start with the very first topic who is a data analyst. Well a data analyst is the one who analyzed all the numeric and other kinds of data and translate it into the English language so that everyone can understand now this data is used by the upper management to make informed business decisions. Now the main responsibilities of a data analyst include data collection correlation analysis and Reporting next is data engineer
. So a data engineer is the one who is involved in preparing data for analytics calor operational users. So these are the ones who develops constructs test and maintain the complete architecture of the large scale processing system. Now a typical data ingenious, they include building data pipelines to put all the information together from different sources. They then integrated Consolidated for the clean and structure it for more analytic 6. So this probably varies from organization to organization. Next is a data scientist. A data scientist is a one who analyze and interpret complex Digital Data for instance statistics of a website. Now a data scientist is a professional who deals with your large amount of structured as well as unstructured data. They use their skills in statistics programming machine learning in order to create strategic plans now data scientist and data engineer job roles are quite similar but a data scientist is the one who has the upper hand or all the data editor activities when it comes to business related decision-making data scientist have the higher proficiency.
Now, let's look at the road map which correlate these three job roles to start off with most entry level professionals interested in getting into Data related jobs start off as data analyst. So qualifying for this role is as simple as it gets. All you need is a bachelor's degree and good statistical knowledge. Well strong technical skills would be a plus and can give you an edge over most other applicants other than this companies expect you to understand data handling modeling and Reporting. Along with the strong understanding of the business moving forward the transition between a data analyst role and a data engineer one is possible in multiple ways. You can either acquire a master's degree in a related field or gather amount of experience as a data analyst adding onto the skills of data analyst a data engineer needs to have a strong technical background with the ability to create an integrated API also need to understand data pipelining and performance optimization. The next milestone in data Engineers Courier is becoming a data scientist while there are several ways in which a data engineer can transition into a data scientist rule the most seamless one is by acquiring enough experience and learning the necessary skills. Now these skills include Advanced statistical analysis a complete understanding of machine learning and predictive algorithms and data conditioning next.
. Let us compare these different roles on the basis of their skills their roles and responsibilities in their day-to-day life and finally discuss the salary perspective first. Let us see what are the different skill sets required for data. Less data engineer and data scientists. So as discussed a data analyst primary skill sets revolves around data equation handling and processing now an ideal skill set for this profile would include data warehousing Adobe and Google analytics. Then you must have programming knowledge scripting and statistical skills reporting and data visualization using various tools database knowledge like SQL or anything and spreadsheet knowledge. Well a beginner's level programming experience would also Aid in building better statistical models as well. Now a data engineer on the other hand requires intermediate level understanding of programming to build our algorithms along with a Mastery of statistics and math most companies hiring for data Engineers. Look for skills, like data warehousing and ETL or you can say extract transform load then it has some Advanced programming knowledge. Also Hadoop based analytics plays a vital role then they must have in-depth knowledge of databases data architecture and various machine learning concept or you can say algorithms knowledge fine. Any a data scientist needs to be master of both the world's data starts and math along with in-depth programming knowledge of machine learning and deep learning. Well the job description for an ideal data scientist include statistical and analytical skills.
. Then you have various data mining activities machine learning and deep learning principles, or you can also add up to its various algorithms. Then a data scientist should also have in-depth programming knowledge or you can see such as in SAS are or python languages now that you have a complete understanding of what skill sets. You need to become a data analyst a data engineer or a scientist. Let's look at what are the typical roles and responsibilities of these professionals now the roles and responsibilities of a data analyst data engineer and the data scientists are quite similar as you can see from the slides now a typical data analyst is responsible for statistical analysis and data interpretation. They should also be well familiarized with various data reporting and visualization tools. For example, if I working on python, you should know the various python libraries like matplotlib see zbornak. Job, and similarly. If you are familiar with our language, then you should go for ggplot or any other visualization library. Then a data analyst should never compromise on the quality. This should also be very friendly with data. It works for example data equation maintenance pattern detection data cleaning and things like that.
. Next comes to data engineer well adding onto the work of data analyst a data engineer also maintains the architecture the development of it and testing of that architecture. So it basically involves developing data sets using machine learning techniques, or you can say a data engineer should also know how to deploy these machine learning and deep learning models and all the other tasks assigned with them. So for example, predictive modeling searching for hidden patterns and similar tasks, then comes your data scientist. Now a data scientist on the other hand is responsible for a lot of tasks is responsible for mining of data then develop operational models. Then a data scientist should also be explored in machine learning and deep learning techniques. You should also be scale in data enhancement and sourcing method These another important aspect of being a data scientist strategy planning and data integration. Now a lesser-known task of a data scientist is impulsive or you can say or ad hoc analysis and finally a data scientist must be skilled at anomaly detection and performance tracking now after these two interested topics. Let's now look at how much you can earn by getting into a career in data analytics data engineering or data science. Now as you can see the typical salary of a data analyst is just under fifty nine thousand dollars per year there as a data engineer can earn up to ninety thousand eight hundred and thirty nine dollars per year. Whereas a data scientist can earn up to ninety one thousand four hundred seventy dollars per year
Who will give you your money at all? You will take them from parents, friends or crowdsourcing from strangers Typically, a start-up company issues around 100,000 shares that are equal pieces of property. You have to decide who gets how much from them. You agree to allocate 40% to each founder and 20% to a wealthy family friend who buys them for $ 50,000. This is called an investment, and at such an early stage in your startup it is called "Sowing Investment" -SEED Investment The money he pays now becomes the property of the company. If it fails in the near future, which statistically speaking is almost certain scenarios, he he probably won't see any more of them. $ 50k for 20% of the company makes your business worth $ 250,000, which estimates your 40% to 100 thousand. Not bad. Please sign here, here and here. Congratulations, you started your company and completed your first round of investment. It's been a year. You have passed a successful trial with your customers. It's time to hire more staff and rent not only a super, but a small office space. The 50 thousand dollars have only made you here. It's time to collect your first big cash round. You will do so in the so-called Series A Investment Round. Looking for a $ 1 million investment. This time you are contacting angel investors and venture capital funds, briefly referred to as VCs. VCs are people who work for venture capital firms that raise venture capital funds. They take money from other people by investing in new risky projects similar to yours. Angel investors are people who professionally invest their equity in young companies. Often, they are former entrepreneurs who successfully sold their own company years ago And now they are looking for startups to help. Contacts with several angels and VCs have already been made. Some you have found on the Internet, others through acquaintances and colleagues. You start sending emails. You send them a business plan. Usually, your business plan doesn't interest them much. The team is important to them. Is he competent? Is the idea special? They know it's not easy for you. What have you achieved here? Is it promising? What more could you have achieved? Do you set yourself big goals? You have several Skype conversations. A little general talk, a lot of business talk. Explain your idea? Piece of cake. You've done it many times before. They ask you difficult things like if you've heard of another startup similar to yours. How are you different? You're grabbing their interest. You get a second call. Third call. You meet in person. They may invest. It's time to talk about a company valuation. There are 2 types of appraisal - Before and after the investment money. The Pre-Money rating is how you value it right now. The After-Money score is the sum of the Pre-Money rating + the investment you want to take. This is the one you usually mention as you negotiate. Because the investment divided by the post-investment value is equal to the shares of the investors in your startup. Investors typically strive for a lower "After-Money" rating in order to obtain a higher return. You want the opposite. High score to keep a bigger share. You offer a $ 8 million "after money" rating. For the Investor who gave 1 million receives 12.5% of the shares. After a few weeks, you see 2 suggestions on your desk. One VC proposes to invest $ 1 million in a $ 6 million "after-money" valuation. The angel you spoke with suggests that you invest 500,000 at a "after money" valuation of 5 million.In its essence, it is just another type of raising capital. Here again your company issues new shares with the difference that this time the investor is neither angel nor VC, but the public. The day you are listed, your company issues a certain number of shares on the market and from there people can buy and sell each other. In addition, you own tradable securities that are almost as good as the cash. Their price varies every day. You can sell your shares in the stock market at a market price when you request, except for the so-called. IPO "locked periods" that are the topic of another lecture. You place the stock at a starting price of $ 64 and reach $ 70 as early as the first day of trading. Due to stock splits along the way, you now have 10 million shares in your company. Your personal wealth is over $ 700 million. You could cache them, but do you really want one? It was like yesterday when you two had only one dream. You are now one in a million. You have accomplished a great deal and still countless things to do. Although investors call it an exit, for many entrepreneurs this is only the beginning. Subtitles from the Amara.org community
So we have another question here-- this is a little more security-oriented-- about can we explain a little bit more about what ephemeral mode is? So we mentioned, in the deck, about a unique feature-- security feature-- called Ephemeral Mode. Ephemeral Mode is unique to Chrome OS, and it gives it the ability that every time a user enters and exits their session, that all the local data within their profile is white. So whether it's downloaded content that they put in their Downloads folder, cached data, passwords-- anything that may have been saved during their user session is wiped on the exit of their session, and every new session created is a blank profile. And no data is stored or captured, and is wiped clean every time. This is, as we referred to back in the deck, keeping a low data footprint. So it's a very popular method for organizations to employ Ephemeral Mode, because they can be ensured that there is no data left behind on the device. And our last question here is a little bit on networking and security tools. What networking and security tools are available for Chromebooks? Most of the major manufacturers of networking applications provide applications both in the Web Store-- the Chrome Web Store-- and on the Android market for networking applications. So whether it's VPN applications or proxy applications, most of the major manufacturers are available within the Google Web Store, and on the Android Play Store. I'd say the more popular ones are obviously Cisco and Palo Alto, but many others exist from the other network providers as well. So I think that wraps up our questions that we've gotten from our audience. I just want to thank everyone for tuning in, and to please visit Cloud OnAir to discover more content from Google Cloud experts.
. So isn't this amazing guys now looking at these figures of a data engineer and a data scientist, you might not see much difference at first but delving deeper into the numbers a data scientist can earn twenty to thirty percent more than an average data engineer. Also, it's been proven by various job posting from companies like Facebook IBM That basically coat salaries up to one thirty six thousand dollars per year now taking this into consideration. We also have an expert created data science master's program where you can find all the necessary details to become a radar scientist. It include 12 courses were 250 Plus hours of Interactive Learning along with the Capstone project. You can find out all the details curriculum that timings everything over here and let me also tell you one more thing guys. You will also be awarded with an industry-recognized certificate in the end. So do check out this page guys. I will drop the link in the description box below. Well, that's all for today. I hope you guys like this session have a lovely weekend.
