[0]

so you've heard of this thing called

[1]

table' you've seen a demo of it or

[4]

you've seen it in action but now you're

[6]

about to dive in for the first time but

[8]

before you do you're probably wondering

[10]

what all the hype is about what can it

[12]

do what can't it do or maybe even more

[15]

basic than that

[16]

what is table' well on all of those

[18]

that's where I get involved

[20]

I'm Tim aka Tablo Tim and in this video

[23]

I'm going to walk you through the

[25]

tableau platform in under 10 minutes in

[28]

fact if this is the first time you're

[30]

hearing about Tablo perfect a few house

[33]

rules for the video though be sure to

[35]

check the description for links to some

[36]

of the resources I mentioned and lastly

[39]

if he gets the end of the video and you

[40]

[42]

[44]

and enable alert so you don't miss out

[47]

on the videos like this that I'll be

[48]

releasing in the near future it really

[50]

helps my channel out ok enough begging

[53]

let's get stuck in Tablo was founded in

[55]

January 2003 it was an academic spin-off

[58]

by Chris Christian and Pat in an

[61]

academic paper way back in 2002 they had

[65]

a simple idea and it was this what if he

[67]

had a tool that allowed you to view your

[69]

business data in a visual way now if

[72]

you're hearing that you're probably

[73]

thinking well Excel existed slash

[76]

already does that

[77]

I can make charts tables and all sorts

[79]

in Excel or any other tour as a matter

[81]

of fact so what's different about table

[83]

or put simply one thing tableaus

[86]

innovation was entirely focused around

[88]

visual analysis what does that mean okay

[91]

let's take one step back and then visit

[93]

the typical workflow in every business

[95]

that collects and uses data to make

[97]

decisions let's say I run a superstore

[99]

we make sales every day and the data

[102]

from these cells is stored in a database

[103]

a small business might just record these

[106]

in a spreadsheet an excel file or if

[108]

your web first company like a tech

[110]

startup you might make it available via

[112]

the web or the cloud at the end of each

[115]

month quarter or even year you'll want

[118]

to review these cells to see how you're

[120]

doing in order to do that you need to

[122]

collect the data for the period you're

[124]

looking at make sure it's correct and is

[126]

make sure there's no mistakes in it then

[128]

hand it over to an analyst or a data

[130]

scientist to do their thing

[132]

they in turn take the data and start

[134]

exploring it to find insights this might

[137]

just mean they're looking for new trends

[139]

and patterns or they may already have

[141]

some questions that they want to answer

[143]

for example did they meet the target

[145]

this month once they have those

[147]

questions and answers

[149]

it's time to share those insights with

[151]

colleagues so decisions can be made

[152]

about what to do next they might build a

[155]

basic report or in large business a

[157]

dashboard with lots of perspectives

[159]

contained in one view in some really

[162]

old-school companies you might even get

[163]

packs with every report printed out for

[166]

every single aspect of the business

[167]

senior colleagues or decision makers

[169]

will then use these reports to reflect

[172]

on how the business is performed set new

[174]

targets or goals make changes to targets

[177]

and then share these decisions back out

[179]

to the business once these goals are

[181]

shared staff need to be able to monitor

[183]

what's going on so we end up going back

[186]

full circle to the beginning and the

[188]

cycle repeats this process is typically

[191]

termed as analytics or business

[193]

intelligence and whether you're a small

[195]

one-person outfit or a large corporate

[198]

business with hundreds of thousands of

[200]

employees you have the same need ok so

[204]

we now understand the analytical process

[205]

where does tableau come into all of this

[208]

well the short answer is all of it

[211]

let me explain let's take our cycle and

[214]

rearrange it a little and take it from

[216]

the top

[218]

tablo has six key products which aims to

[221]

solve some of the problems outlined in

[223]

is simple to use and connected platform

[226]

the first stage of this cycle where the

[228]

store collects the data and keeps it

[230]

safe is called transaction processing by

[233]

nerds like me it ensures the data from

[235]

each purchase is captured ship to the

[238]

customer and then stored in a database

[239]

at the time of this recording tablet

[242]

don't currently have a product that

[243]

meets this need no database as such but

[246]

you will often hear about a file type

[248]

called the tableau data extract TDE in

[251]

short or more recently hyper this is the

[254]

file format tableau likes to use to

[256]

store on process data and has some

[258]

smarts built into it check out my

[260]

podcast on this topic in the description

[262]

below ok next up the most important part

[265]

of the process connecting to your data

[267]

and analyzing it there's two steps here

[270]

firstly you see most of the time data is

[273]

stored correctly that's a good thing but

[275]

often you might look at data and spot a

[277]

mistake for example a transaction where

[279]

the wrong item was scanned or maybe a

[281]

missing category in order to handle this

[284]

you'll need to fix these mistakes either

[286]

manually or in bulk at scale in my field

[290]

that's called

[290]

either data prep data cleansing or if

[293]

you want to be a real consulting nerd

[295]

the process of handling this is called

[297]

ETL extract transform and load and for

[300]

this table' have a fairly new product in

[303]

tableau prep builder it allows you to

[305]

clean shape and transform your data by

[307]

making it really easy to do things like

[309]

pivoting your data removing empty fields

[312]

replacing fields or merging fields from

[314]

different data sources it does all of

[316]

this with a visual and easy to

[318]

understand interface again I've done

[320]

some basic intro videos on this channel

[322]

so check those out but I'll be doing
