Data Lake Fb

Do you like your data curated?

The key to understanding the distinction between lakes and warehouses for data storage is the notion of curated data.

Data lakes are typically not modelled (just files of data from disparate sources brought together in a file system), so data can be pulled together at the last moment to answer the question of the day. This is called ‘’late bind’’. It needs different technologies to work well together and can be difficult to guarantee good performance. However, it can be done with the right effort and investment.

By contrast, in warehouses the data is curated.

Rob Kellaway, Head of Data Design, explores which is better.

Functional Challenge

In fact, it's not possible to say whether lakes or warehouses are better. This is more a question of which is the most cost effective solution and how sure you are that you know the questions you need to ask. These considerations are the ones which will ultimately dictate the choice.

They are two specific methods of storing data for reporting purposes. The data lake is better suited to the needs of data scientists working on use cases in a lab environment. The multiple data sources and the ability to quickly prototype analysis is a natural fit for data scientists to gain insight by bringing them all together to make sense of what is being detailed.

On the other hand, a data lake is not effective for running operational reporting, due to the uncurated data. Data warehouses are usually populated with structured, good quality data, which has been verified at source.

Future Developments

Hybrid systems are being developed, which enable lakes and warehouses to work in tandem via the use of Cloud technology. Rather than always productionise in the data warehouse, we will see an eco-system of technologies emerge, and we will pick the right platform, for the right reason, at the right price point, and ensure consistent governance over our data.

Data Engineering

Data engineers will need to continue to work with data scientists to ensure that hybrid systems work well together.

At Nationwide, we are looking for data engineers and data scientists to take us further on a journey to provide legendary service and to continue to serve our members in the best way possible.

Clouds And Laptop

Cloud Busting

Traditionally, data storage has been the preserve of PC hard drive or the server rooms, originally located onsite at big organisations. Over time, data centres were moved away from the main administrative offices.

Today, more use is being made of cloud computing, where data/applications are held by online storage companies, who are responsible for the infrastructure, rather than the organisations who own the data. Cost efficiency is a major factor in this move, but what are the others?

Why move to Cloud?

Advocates of public and hybrid clouds argue that such computing allows organisations to avoid or minimise upfront infrastructure costs. They also claim that cloud computing allows enterprises to get their applications up and running faster.

  • The evolution has been supported by:
    the increasing number of high-capacity networks being available
  • the lowering cost of appropriate computers and storage devices, and
  • the widespread adoption of hardware virtualisation and service-oriented architecture.

Considering Cloud?

Organisations need to be aware of several factors before joining the cloud revolution, namely:

  • the pricing model, which can be far more complicated than expected
  • the security measures employed by the cloud provider
  • the latency or speed of traffic across the cloud network. In some parts of the United States, the distances mean it is quicker to physically carry the storage devices to the local data centres than wait for the uploads to complete over the internet.

Data Engineering and the Black Hole

There is a buzz around data engineering. Nationwide Building Society is recruiting a significant number of data engineers, and with good reason.

Data scientists have hit the headlines with the release of the picture of the Black Hole. However, a data scientist is only as good as the data they have access to. Rob Kellaway, Head of Design, explores the part Data Engineers play.

Mature organisations will store their data in variety of formats across a variety of platforms. This is where data engineers come to the fore. They are responsible for building processes that transform that data into formats that data scientists can use. Data engineers are as important as data scientists but tend to be less visible, largely because they are further from the end product, the analysis.

Boldly going where no data scientist has been before

Data engineers are a key component in any organisation’s drive for efficiency. They make the job of extracting value from multiple data sources possible. Data engineering is the foundation upon which silos of data can be networked together, ensuring that the quality, accessibility and timeliness of the resource is appropriate to convert into tangible value for the organisation. And greater automation of processes supports the work of data engineers, making pipelines of data sources more efficient for data scientists to use.

At Nationwide, we are investing significantly in people and technology to increase the value of our data. We recognise data engineering is a key component of our Data Strategy.

We are also looking at DataOps, which is the extension of DevOps values and practices into the analytics world. The DevOps philosophy is about seamless collaboration between developers, quality assurance teams and IT Operations. DataOps does the same for the admins and engineers who store, analyse, archive and deliver data.
