 students welcome to module 38 of your introduction to data science course in this module we will discuss some of the esquial commands one thing we discussed is like a chord operation that you have to create, delete, write but to do that you have to understand the command structure or it is called syntax, like any language, for example you write English, French, Spanish so when you talk and write it there is a difference when you write it has to be grammatically correct similarly in the esquial there is a command, there is a syntax, there is a way that every command is basically an instruction to the database where you as a human being, as a data scientist, as a data architect or data engineer, because this database, your rdbms is a software application like your front end application, similarly this database is an application and it is developed in a special way and then this capability is created in it that whatever it is called it understands it and performs it according to it but if you tell anyone something in English then it is necessary that that person should have English similarly if you know, similarly if you want French or any other language similarly the computer, the software program if you write Python then Python has its own syntax if you write in Scala then Scala has its own syntax similarly your esquial has its own syntax and there is a little difference in it like the different proprietary languages like myesquial or the esquial of Microsoft or Oracle there is a little difference in their esquial but in principle they are all the same there is a little difference in it just to keep the individuality just to claim that we are different in the market otherwise they are almost the same if you have developed your skills in a single esquial then you can easily develop your skills in another esquial and I have seen that a data scientist or a db developer he can work with a little bit of effort in 2-3 databases now you have to manage the data in a specific way if you have to read it, write it, make a summary, make a summary so whatever work you have to do if you have already designed the database in a certain way then accordingly you have to tell it that what you will do first in this as a database developer or data engineer you select the database the purpose of selecting the database is that you select the application that I have to access on which computer it is now we will keep one thing in mind that the world we are talking about in the 21st century mostly we are talking about an integrated environment where the whole world is integrated with each other so if you have or as a system administrator if you allow someone else to access their data that is a separate subject but just to develop your understanding that the environment we are living in and the environment we are going to be in that is going to be more and more integrated where the data can be somewhere the developer can be somewhere the data scientist can be somewhere he can be in a separate room or in a separate city or in a separate continent actually this is happening today that the people who work in Asia their clients they are in Europe and North America so this is how they work so just when we refer to these things then you will understand that we are an integrated or distributed but connected निन्का सद लेगार, जो व्रोंगा inverse is यह सब से पहले एक उस टेटाबेस में तो आप चलग, यह आप उस टेटाबाल का नाम लिखते हैं, उसके बाद आप कन्टिशन कोई लगातें के वेर, फर्ज गरें के मैं खेतां के सलेक्ट, वेर एज यह स्टुडन्ट का यह तुबारा से अप एकजमपले, अमारे पास वर्च्टिल यूनिवर्स्टी के पिछले बीस सालों के सारे स्टुडन्ट का देट हैं, तो गर में यह खेतां के सलेक्ट, वेर जो आप का जो कोर्ष है, वो डेटा सायंज तो शहाथ अपी शुरू होना है, यह तो नहीं मैंज्मेंच्चाइस, MSE मैंज्मेंच्चाइस, student with grade A from this year to this year, तो यह बैसिल्ग आपके वो सारे पेरमीटर्ज है, जो के आप ने उस में बताने हुते है, यह यस तरान से पेर्टा स्लेक्ट करते है, तो जब यह आप एक स्लेक्ट कमान लिख के अंटर करते है, तो फोरन नीचेवाला इस ता जो आपने पिषनी एक सलाइट में देखाता, तो उस में वो उसका देटा शूँ होना शूरू हो जाते है, तो आपको पताच यह जाते है, यह जो मैंने कमान लिख की ती वो थीख ती, उस में सम्टाएम यवन जु फेसन एरर, के अगर आपने कोमा गलत लगा दिया, कोई जिसे ग्रेमर के रूल होते है, अगर कही पे आप से कोई मिस्टेग होगी, आपको पताच यह जाते, अगर मेरे आररेडा है, अप उसको करकत गरते है, इस भर एजी फर यु, अप उसको अगर लोगिक फीट मैं फरी अगर प्रट खुर्ट कर से थे, इमीजेटली कोड रूलेंक बोग च्झारे फोरम्द होते है, अपके डिफरी बलौगs अते वाग की अपनी पूरन नहीं तो आपको अपनी प्रव्लम का रहा है वहुंग ते कुछ भी ब्लौग पे अपनी भी रहा है वहां से कोई तोई जो है देखें की अला की नेग बन दा पी help करेगा अपको आपनी प्रवोलम का जोया जोया सूलुचन उसमें मिल जाते तो ताटिस खो इप वगष इस में ये जो आप साझट के जो देखुएश में शक्रीन पे
