The Logical Data Fabric: A Single Place for Data Integration

Published

on

The ability to provide a
single place for instantaneous data access can mean business continuity or
closure. Many nations found this out during the recent global crisis, as countries
needed to know the number of tests taken and the infection rate in order to
determine both the virus’ spread and who to quarantine. Unfortunately, the
required data did not become available in time to prevent a widespread
lockdown, shuttering many businesses. Simultaneously, demands for immediate integrated
critical data only increased.

Getting high-quality data now,
for discovery and solutions, is a top priortiy for Ravi Shankar, the Senior
Vice President and Chief Marketing Officer for Denodo. In a recent DATAVERSITY®
interview, Shankar explained how data virtualization technologies are evolving and
creating a logical data fabric, putting data all into one place and enabling
better and faster business decisions.

He described past attempts to do this physically and the resulting challenges. Shankar advised the necessary characteristics for a logical data fabric and how data virtualization delivers, weaving data together into one place and advancing the future.

Data Integration and the Physical Platform

Ravi Shankar has seen the data market come a long way in the last thirty years, by improving on the physical platforms, starting with databases. Shankar noted:

“People needed to analyze and make sense of data in one place. The database became a popular solution to store and find all this information, rather than dealing with data spread out across different locations.”

As the drive for databases gained momentum, multiple databases and vendors emerged to solve different kinds of business problems. Companies like Microsoft and Oracle sold database products at a low cost, overtaking older solutions. Fast forward to the 1990s. Business required integrating all the data from transactional and operational databases into one location, said Shankar. Companies that wished to consolidate data spurred the data warehouse concept. He remarked, “Once again, we tried to get a single source of information, where we could do our analysis.”

Data warehouses became widespread and diverse. As a result, many companies ended up with several data warehouses. Data marts (subject-oriented repositories that pipe information from the data warehouse for specific business services) emerged, adding to the data warehouse glut. To solve this problem, data warehousing vendors promoted one single enterprise data warehouse, which received some adoption. So, data warehouses solved the problem of housing all data in one location for analytical purposes, but they were limited only to structured data.

However, around the turn of the millennium, unstructured data grew from social media and started to appear also in the cloud. The data warehouse technology could not handle this unstructured data. So, “data lakes grew as desired repositories that could store any data type in its raw format and leave the normalization of the data to the time of access,” explained Shankar. Well, companies ended up with multiple data lakes (one for marketing, one for sales, etc.). But today, the preference remains to centralize all data. Shankar said:

“There has always been a need to have data in a single place because it is easy to find and use. But data gravity pulls the data back to different sources, since the data is continuously updated there as the business operates. I hypothesize that the rate of change of data in the sources, as well as invention of new data types, far exceeds the human capacity to physically pull them all to one focal point.”

Having one physical data repository has not been working. He advocates instead for a data view through a logical data fabric. He added:

“A logical data fabric is becoming more popular in knitting all the disparate data together. Leave the data where it is stored and give the business a unified view. If you try to replicate and bring that data together in a repository, moving that data takes time and costs more to store. In the meantime, the data gets out of synch, needs to be fixed and accessible to use. This approach, a physical data fabric, does not provide information immediately. A logical data fabric makes sense, providing real time access to the source much faster.”

Data Virtualization and The
Logical Data Fabric

The logical data fabric, according
to Shankar, relies on three characteristics:

  • Physical Location Should Not Matter: Logical
    data fabric can connect multiple sources in different places. Whether that data
    lives in the cloud, a corporate data center, or with a third-party entity
    (e.g., a supplier or vendor), logical data fabric can link all this data
    together.
  • Data Format Should Not Matter: A logical
    data fabric solution focuses on joining data in one view, whether structured,
    unstructured, or semi-structured. Picture data in data warehouses, XML
    documents, email, Word documents, and Hadoop all sewn together.
  • Latency Should Not Matter: Data may be
    static, as in the records sitting in a data warehouse, or in motion, as it
    streams from instant messaging or live video. A logical data fabric needs to
    handle both types of data in whatever timeframe generated.

Shankar sees data virtualization as a data abstraction layer knitting together “disparate data in real time.” Data virtualization keeps the integrated data up-to-date in this data layer and accessible to the user in real-time as data updates or changes in the sources. It provides a “universal semantic layer across multiple consuming applications,” and:

“The data virtualization layer knows what data resides and where. The technology brings them all together immediately into a coherent view (e.g., a chart, a table, or a report). The moment the business user receives the information, he or she can take action, just in time, say to contact the most profitable customers and upsell and improve those users’ experience.”

Data virtualization underpins the
logical data fabric, independent of data placement, type, and lag between
inputs and outputs. Shankar says (and Gartner affirms) that data virtualization
represents one of the more stable technologies and the fastest-growing data
integration style. Many companies leverage data virtualization. But what data
virtualization solution merges data fast enough for a business to chart a
course of action and implement it successfully?

A Data Virtualization Product that
Performs Promptly

Denodo provides data virtualization that performs promptly. The company’s experience goes back about twenty years when the CEO along with the CTO published a research paper leading the way. Gartner featured Denodo as the top fastest-growing data integration center. Shankar explained that the company has grown, “fifty percent year over year,” due to increasing data virtualization usage. But Shankar and Denodo are not resting on its laurels, especially with the rapidly escalating Coronavirus pandemic situation.

The company has launched an initiative called Coronavirus Data Portal which is an open, collaborative platform that uses the power of data virtualization to integrate various COVID-19 datasets from across the world and make the combined data available to researchers to help accelerate solutions to this deadly disease.

He stressed:

“Speed remains key to delivering data, especially in real-time. The person who has 1 billion records of data in Hadoop and 200 million records in a customer relationship management (CRM) database needs to have it all combined in real time. Denodo has three or four layers of performance optimization techniques to address this need and make data more quickly accessible.”

Shankar and Denodo have a number
of functionalities currently in their product, including:

  • Dynamic Query Optimization: They
    innovated and implemented dynamic query optimization. According to Shankar, this
    feature, “figures the computing load on the systems during runtime, and then shifts
    the work to a system less burdened, to search the data much faster.” When most
    other data virtualization engines could do static optimization, Denodo could
    implement this function in real time.
  • MPP Engine: Denodo’s product leverages in-memory processing — engineering making algorithms more efficient by requiring fewer central processing units (CPU). Since Hadoop systems became more popular, requiring more memory, Denodo can handle this.

Shankar said:

“In the case that computing needs to pull tons of data, we put the data to an in-memory system and process it on the spot. Denodo returns the data much faster. Furthermore, a cache in our system accelerates queries.”

Other features include:

  • Summarizing information: They embrace
    getting aggregated information fast, through summary tables, thus speeding up
    queries.
  • Automation Through AI and Machine Learning:
    AI and ML capabilities automate some manual functions and repetitive tasks.
    “The system learns and proposes resources needed for more efficient processing,”
    said Shankar.
  • Adding a Data Catalog: Customers have
    self-serving access to do data analysis, search it, and understand the meaning,
    through a data catalog.

Enabling analytic use cases with big data, where data scientists can search data at once, is a key necessity. Shankar said:

“We bring data together so that data scientists build models required for cost and price optimization, and salespeople can leverage this information immediately when pricing to their customers.”

In a world where crisis events can
unfold rapidly, business functioning means everything. People need data now.
Shankar stated, “We provide abstraction. We have the location-agnostic
capability to take care of data from on-premises to the cloud. We provide
translation for our business users.” Most of all, it’s important to get data
promptly to the user for just-in-time action.

Synthetic gene circuits as tools for drug discovery

Published

on

Within mammalian systems, there exists enormous opportunity to use synthetic gene circuits to enhance phenotype-based drug discovery, to map the molecular origins of disease, and to validate therapeutics in complex cellular systems. While drug discovery has relied on marker staining and high-content imaging in cell-based assays, synthetic gene circuits expand the potential for precision and speed. Here we present a vision of how circuits can improve the speed and accuracy of drug discovery by enhancing the efficiency of hit triage, capturing disease-relevant dynamics in cell-based assays, and simplifying validation and readouts from organoids and microphysiological systems (MPS).

Nokia lifts full-year forecast as turnaround takes root

Published

on

HELSINKI (Reuters) -Telecom equipment maker Nokia reported a stronger-than-expected second-quarter operating profit on Thursday and raised its full-year outlook as promised, thanks to a turnaround of its business.

The Finnish company’s April-June comparable operating profit rose to 682 million euros ($808.51 million) from 423 million euros a year earlier, beating the 408-million euro mean estimate in a Refinitiv poll of analysts.

Shifting geopolitics and a sharp round of cost cutting have put Nokia firmly back in the global 5G rollout race just a year after CEO Pekka Lundmark took the reins, allowing it to gain ground on Swedish arch-rival Ericsson.

“We have executed faster than planned on our strategy in the first half which provides us with a good foundation for the full year,” Lundmark said in a statement on Thursday, but added that Nokia still expects the 2021 second-half results to be less pronounced.

Nokia said it now expects full-year net sales of 21.7 billion-22.7 billion euros, up from its prior estimate of 20.6 billion-21.8 billion euros, with an operating profit margin of 10-12% instead of the 7% to 10% expected previously.

The company had announced on July 13 that it would raise its outlook, but did not provide any details.

Robinhood, gateway to ‘meme’ stocks, raises $2.1 billion in IPO

Published

on

By Echo Wang and David French

(Reuters) -Robinhood Markets Inc, the owner of the trading app which emerged as the go-to destination for retail investors speculating on this year’s “meme’ stock trading frenzy, raised $2.1 billion in its initial public offering on Wednesday.

The company was seeking to capitalize on individual investors’ fascination with cryptocurrencies and stocks such as GameStop Corp, which have seen wild swings after becoming the subject of trading speculation on social media sites such as Reddit. Robinhood’s monthly active users surged from 11.7 million at the end of December to 21.3 million as of the end of June.

The IPO valued Robinhood at $31.8 billion, making it greater as a function of its revenue than many of its traditional rivals such as Charles Schwab Corp, but the offering priced at the bottom of the company’s indicated range.

Some investors stayed on the sidelines, citing concerns over the frothy valuation, the risk of regulators cracking down on Robinhood’s business, and even lingering anger with the company’s imposition of trading curbs when the meme stock trading frenzy flared up at the end of January.

Robinhood said it sold 55 million shares in the IPO at $38 apiece, the low end of its $38 to $42 price range. This makes it one of the most valuable U.S. companies to have gone public year-to-date, amid a red-hot market for new listings.

In an unusual move, Robinhood had said it would reserve between 20% and 35% of its shares for its users.

Robinhood’s platform allows users to make unlimited commission-free trades in stocks, exchange-traded funds, options and cryptocurrencies. Its simple interface made it popular with young investors trading from home during the COVID-19 pandemic.

Robinhood enraged some investors and U.S. lawmakers earlier this year when it restricted trading in some popular stocks following a 10-fold rise in deposit requirements at its clearinghouse. It has been at the center of many regulatory probes.

The company disclosed this week that it has received inquiries from U.S. regulators looking into whether its employees traded shares of GameStop and AMC Entertainment Holdings, Inc before the trading curbs were placed at the end of January.

In June, Robinhood agreed to pay nearly $70 million to settle an investigation by Wall Street’s own regulator, the Financial Industry Regulatory Authority, for “systemic” failures, including systems outages, providing “false or misleading” information, and weak options trading controls.

The brokerage has also been criticized for relying on “payment for order flow” for most of its revenue, under which it receives fees from market makers for routing trades to them and does not charge users for individual trades.

Critics argue the practice, which is used by many other brokers, creates a conflict of interest, on the grounds that it incentivizes brokers to send orders to whoever pays the higher fees. Robinhood contends that it routes trades based on what is cheapest for its users, and that charging a commission would be more expensive. The U.S. Securities and Exchange Commission is examining the practice.

Robinhood was founded in 2013 by Stanford University roommates Vlad Tenev and Baiju Bhatt. They will hold a majority of the voting power after the offering, these filings showed, with Bhatt having around 39% of the voting power of outstanding stock while Tenev will hold about 26.2%.

The company’s shares are scheduled to start trading on Nasdaq on Thursday under the ticker “HOOD”

Goldman Sachs and J.P. Morgan were the lead underwriters in Robinhood’s IPO.
