As the name suggests, data lake is a large reservoir of data – structured or unstructured, fed through disparate channels. The data is fed through channels in anad-hoc manner into these data lakes, however, owing to the predefined set of rules orschema, correlation between the database is established automatically to help with the extraction of meaningful information.

2. INTRODUCTION
The volume, variety, velocity and veracity of big data are getting increasingly complex
each passing day. The way the data is stored, processed, managed and shared with
decision-makers is getting impacted by this complexity and to tackle the same, a
revolutionary approach to data management has come into picture. A data lake.

WHAT IS A
DATA LAKE?

4. ©Denave
As the name suggests, data lake is a large reservoir of data – structured or
unstructured, fed through disparate channels. The data is fed through channels in an
ad-hoc manner into these data lakes, however, owing to the predefined set of rules or
schema, correlation between the database is established automatically to help with
the extraction of meaningful information.
It provides high level of flexibility in terms of interaction with and leverage of the data.
In general, data lakes are used to store data when you’ve a constant stream of
unstructured data coming into, such as, web interactions, product logs, IoT sensors,
app usage etc.
Simply put, along with the on-premises data, it is the real-time data which fills up the
data lake, upon which are then used the principles of machine learning and analytics
to make it relational.
The global data lakes market is expected to grow at a CAGR of
approximately 28% during the forecast period 2017-2023, to
touch $12.01 billion by 2024 & $+14.01 billion by 2026. 1,2&3

DATA LAKES &
SALES ECOSYSTEM
UNDERSTANDING
THE CORRELATION

6. Sales is no more just about the product alone. Rather, it is more about getting
connected to the customer – at a deeper level. In order to do so, organisations are
becoming data-driven in every sense and they rely heavily on agile technologies to
help them with the analysis and management of data.
With a large wealth of customer data at their disposal, it is that data analysis backed
sales action which acts as a game-changer for organisations. To get the differentiating
edge, firms need to use the customer data in the best possible manner to make
hyper-impactful outreach and better sales interactions.
Following elucidates some of the challenges of sales ecosystem which are solved
by Data lakes:
Need for the Data in Native Format
It may be difficult to believe but since the amount of data being generated by
enterprises is extremely huge, a major portion of that data is discarded. Remaining
small portion is then stored in the data warehouse – for a few years. This happens
owing to the storage capacity, structure restriction, associated costs etc. and most of
the time it happens because enterprises don’t know what to be done with that data,
esp. machine-generated or historical data. Hence, it is dumped away, thus putting a
limitation on the extent of analytics application that can happen.
With data lakes, enterprises save the data without fretting about the structure,
intended use etc. Simply put, you may not know why you are saving the data, but
you’d still do so with the thought that you may need that data someday – thus,
getting as much data as possible in its native format.

intended use etc. Simply put, you may not know why you are saving the data, but

Quashing Data Silos
With data, the case is such that the number of teams or departments you have, that
much variety of data would be there. That database is not centralised and instead
remain in silos because it turns out to be expensive as well as time consuming to
share that data with one another. Consider the case where a department may need
the data from another department – their requirement would be a specific segment of
data in a particular format, Therefore, the department which owns the data will be
conducting all ETL exercises to be able to extract and package the data in line with
the requirement. Extra work equals to extra time and also extra expenses and hence
the delivery team would want to shy away from getting any data request in the first
place or to delay and excuse any request which has already been made, resulting in
data silos.
It is like having an immense wealth with you but not being able to use it owing to the
labours it is going to take to spend it.
This issue is tackled head on with data lakes because there the data ingestion is
almost frictionless since it accepts data without any processing, thus allows for a
deeper data leverage to all with a centralised and transparent access process. Data
ownership doesn’t remain a barrier any more with data lakes.

ADVANTAGES OF
DATA LAKES

9. The acceptance of need for data lakes itself makes visible a lot of benefits which
salespeople can accrue, let’s dig deeper and see what all as an organisation are you
set to gain if your database strategies include leveraging data lakes:
Say good-bye to silos and fragmentation
With data lakes, you get a unified view of everything which comprises the customer
experience – all the data from all the platforms, departments, teams, delivery
channels.
Better preparedness for the customer journey
Since you’ve better knowledge about the customer buying cycle, the high or low
points of his journey, quite naturally the decision-making process is much more
impactful than before.
High yielding campaigns
You’re better equipped than before for generating and assessing campaigns. The
agility and autonomy are rendered by the tools which not only helps you to measure
but also to optimise your marketing investments in real time.
Power to predict
Sitting on the historical data which you’d have otherwise dumped or would have
never been able to analyse, provides you with the power to analyse and establish
predictive models for customer behaviour.

10. All touch point control
You’re also able to trace the journey and behaviour specific to each customer
touchpoint which allows you to rank the point of conversions accurately. Accordingly,
you can adjust your focus on the touchpoints.
Fertile environment for new tools or methodologies
development
Since you own the storage of immense amount of data, you can generate your own
technological environment and a service-oriented architecture which can make the
development of new tools possible.
Intelligent and faster decisions
With dynamic dashboards which work upon varied kinds of data accumulated from
myriad number of sources – external or internal, you get an unmatched business
intelligence right at your tips and thus, decision-making in real-time becomes
possible.
If we put together all the benefits in one basket, the highlight of data lake adoption
would be the provision of an agile 360-degree view data-driven marketing
operations and a faster (and intelligent) response system to any business need.
These will automatically translate into improved customer interactions, enhanced
R&D innovation possibilities and augmented operational efficiencies.

GETTING THE
RIGHT FIT

12. Getting convinced of the immense advantages of data lakes is one thing but
understanding where it fits in your business needs and vision is another thing and
probably the more important one.
A quick assessment of the latter will help in getting the optimal resolution for
your business:
Understand your data type
What is the type of data which forms the majority of your data input/ accumulation? If
it is structured data in generality – traditional, tabular format – data being generated
by HR systems, traditional CRMs etc. then data warehouse is a good option.
Data lakes are beneficial in case if the data you have is unstructured or semi-
structured and it’s getting generated constantly (like a person crosses an in-store ad
and the data is captured by the intelligent display unit to get records of user views
and behaviour). In such a constant stream of data, hundreds of terabytes are
generated and occupy the storage in a matter of time.
In short, your structured data may be more suited for RDBMS while the sensor or
SAAS based data would be more suited for data lakes. If you would use a data lake for
the prior stated data variety then the costs would be exorbitant and unrequired.

13. Understand your data expectation
If the post storage needs from the data are fixed and you need it for specific use
cases, then you’d structure the data in advance for the requite processing. For such
kind of expectation from the data, a data warehouse is best suited, however,
structuring the data has its own costs attached and it certainly limits your ability to
repurpose the data for any other use later on.
With data lakes, comes in the flexibility. You can store now and decide later what you
really want to extract out of that data.
For a set of predefined reports, you may not bother having a data lake but to have
the freedom to analyse and accordingly scale up or innovate, data lakes would be the
best bet.
Understand your resources
While DB technicians or IT team would be able to get a database system in place and
then business analysts can leverage self-service to extract reports out of it, data lakes
would require a different level of expertise. Skilled big data engineers and data
scientists would have to be invested in along with sophisticated tools to form a data
puddle and then a data pond and finally a data lake.
Analyse your data acquisition process
If the data acquisition is happening from multiple sources and is a complex process in
itself -it would mean that you’d be spending a large overhead on ETL techniques in
order to render that data suitable for data warehouse. If you’re constantly spending a
fortune because of a complex data acquisition and thus a cost intensive process, then
it might be time to switch to data lake.
Once you take the plunge into data lakes based on your requirements, remember the
governance part as well and involve the legal & privacy team for required due
diligence.

USING IT
RIGHT

15. Getting the right platform and then getting the data loaded onto it are the first steps
but the real job begins post that.
The interface plays a critical role in adoption and usage of data lake. The scope of
data lake is huge enough that the normal IT function, which is adequate to manage a
data warehouse, can’t be expected to cater to such a wide variety of data as well as a
huge community of users.
Therefore, self service becomes an essential feature for the data lake interface.
It carries these two integral aspects:
• To ensure the access grant in accordance with the level of expertise
• To ensure that people are able to find the right data that they are looking for
For example – a business analysts would need a cooked form of data and a
completely raw data set would not make sense to him/ her, though getting the same
unprocessed data would be necessary for a data scientist. Hence, the interface will
have to have bifurcated zones for different data requirements of divergent set of
audience, such as, partially processed data, raw data etc.

16. CONCLUSION
The whole process of getting the infrastructure in place for the data lake, organising
the data lake (creating zones for various user communities as per their expertise
level), putting up the catalogue of data assets to enable self-service and eventually,
opening it for the users – this complete journey is like a success roadmap for data
lakes.
Such kind of centralisation of data allows for multiple forms of analysis such as
analysing the conversion funnel for improvement areas, creation of a precise
recommendation engine etc. – everything facilitating engaging customer experiences
and explosive business growth.
