When we first thought about a tagline for lakeFS, our recently released OSS project, we instinctively used terms such as “Data versioning”, “Manage data the way you manage code”, “It’s git for data”, and any random variation of the three that is a grammatically correct sentence in english. We were very pleased with ourselves for 5 minutes, maybe 7, before realizing these phrases don’t really mean anything, or mean too many things to properly describe what value we bring. It is also commonly used by other players in the domain that address completely different use cases.
We decided to map the world of projects declaring “Data Versioning”, “Manage data the way you manage code”, and “It’s Git for Data” according to use cases.
The pain: Data analysts and data scientists using many data sets, external and internal, that change over time. Managing access to data sets, and the different versions of each data set over time, is hard and error prone.
The solution: An interface that allows collaboration over the data and version management o. The actual repository may be a proprietary database (e.g. DoltHub), or providing efficient access to data distributed within your systems (e.g. Quilt or Splitgraph). These interfaces grant easy access and management of different versions of the same data set. Most players in this category also provide collaboration of other aspects of the workflow. Most popular is the ability to collaborate over ML models. In this category you can find the likes of DAGsHub, DoltHub, data.world, Kaggle, Splitgraph, Quilt, FloydHub and DataLad.
The pain: Running ML pipelines, from input data to tagged data, validation, modeling, optimizing hyperparameters, and introducing the models to production. There’s no simple way to manage this pipeline, and the very many tools used in the process.
** The solution**: MLOps tools. At this point you might be asking yourself, why would Ops tools be mentioned in the context of the “Data Versioning”? Well, it’s because managing data pipelines is a major challenge in ML application life cycle. Since ML is a scientific work, it requires reproducibility, and reproducibility means data + code. There are a few MLOps tools that enable data versioning, and they include: DVC, Pachyderm and MLflow.

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

The opportunities big data offers also come with very real challenges that many organizations are facing today. Often, it’s finding the most cost-effective, scalable way to store and process boundless volumes of data in multiple formats that come from a growing number of sources. Then organizations need the analytical capabilities and flexibility to turn this data into insights that can meet their specific business objectives.
This Refcard dives into how a data lake helps tackle these challenges at both ends — from its enhanced architecture that’s designed for efficient data ingestion, storage, and management to its advanced analytics functionality and performance flexibility. You’ll also explore key benefits and common use cases.
As technology continues to evolve with new data sources, such as IoT sensors and social media churning out large volumes of data, there has never been a better time to discuss the possibilities and challenges of managing such data for varying analytical insights. In this Refcard, we dig deep into how data lakes solve the problem of storing and processing enormous amounts of data. While doing so, we also explore the benefits of data lakes, their use cases, and how they differ from data warehouses (DWHs).

The COVID-19 pandemic disrupted supply chains and brought economies around the world to a standstill. In turn, businesses need access to accurate, timely data more than ever before. As a result, the demand for data analytics is skyrocketing as businesses try to navigate an uncertain future. However, the sudden surge in demand comes with its own set of challenges.
Here is how the COVID-19 pandemic is affecting the data industry and how enterprises can prepare for the data challenges to come in 2021 and beyond.

CVDC 2020, the Computer Vision conference of the year, is scheduled for 13th and 14th of August to bring together the leading experts on Computer Vision from around the world. Organised by the Association of Data Scientists (ADaSCi), the premier global professional body of data science and machine learning professionals, it is a first-of-its-kind virtual conference on Computer Vision.
The second day of the conference started with quite an informative talk on the current pandemic situation. Speaking of talks, the second session “Application of Data Science Algorithms on 3D Imagery Data” was presented by Ramana M, who is the Principal Data Scientist in Analytics at Cyient Ltd.
Ramana talked about one of the most important assets of organisations, data and how the digital world is moving from using 2D data to 3D data for highly accurate information along with realistic user experiences.
The agenda of the talk included an introduction to 3D data, its applications and case studies, 3D data alignment, 3D data for object detection and two general case studies, which are-
This talk discussed the recent advances in 3D data processing, feature extraction methods, object type detection, object segmentation, and object measurements in different body cross-sections. It also covered the 3D imagery concepts, the various algorithms for faster data processing on the GPU environment, and the application of deep learning techniques for object detection and segmentation.

Data integration solutions typically advocate that one approach – either ETL or ELT – is better than the other. In reality, both ETL (extract, transform, load) and ELT (extract, load, transform) serve indispensable roles in the data integration space:
Because ETL and ELT present different strengths and weaknesses, many organizations are using a hybrid “ETLT” approach to get the best of both worlds. In this guide, we’ll help you understand the “why, what, and how” of ETLT, so you can determine if it’s right for your use-case.
