« Explorer le Paradigme du Data Lakehouse: Une Solution Prometteuse pour les Décisions Basées sur les Données »

Dans l’ère de la prise de décision basée sur les données, le paradigme du Data Lakehouse est apparu comme une solution prometteuse, réunissant le meilleur des data lakes et des data warehouses. En combinant la scalabilité des data lakes avec les fonctionnalités de gestion des données des entrepôts, les Data Lakehouses offrent une infrastructure de données hautement scalable, agile et rentable. Ils fournissent un support robuste pour les charges de travail analytiques et opérationnelles, permettant aux organisations d’extraire plus de valeur de leurs données.

Dans nos articles précédents, nous avons exploré en profondeur le concept des Data Lakehouses. Data Lakehouses: The Future of Scalable, Agile, and Cost-Effective Data Infrastructure a posé les bases en mettant en évidence les principaux avantages commerciaux des lakehouses. A New Era of Data Analytics: Exploring the Innovative World of Data Lakehouse Architectures a examiné de plus près les aspects architecturaux des lakehouses, tandis que Delta, Hudi et Iceberg: The Data Lakehouse Trifecta se sont concentrés sur les trois principales solutions lakehouse: Delta Lake, Hudi et Iceberg.

Afin de mieux comprendre comment le Data Lakehouse peut être mis en œuvre dans un environnement d’entreprise, nous allons maintenant examiner le processus de testing. Le testing est un élément essentiel du développement logiciel et est également très important pour l’implémentation réussie des Data Lakehouses. Le processus de testing permet aux organisations de s’assurer que leurs systèmes sont conformes aux exigences et aux spécifications fonctionnelles et techniques. Il permet également de vérifier que le système est prêt à être mis en production et qu’il fonctionne correctement.

Le testing des Data Lakehouses peut être divisé en trois étapes principales : la vérification des fonctionnalités, la validation des performances et la validation des données. La vérification des fonctionnalités consiste à vérifier que toutes les fonctionnalités du système sont correctement implémentées et qu’elles répondent aux exigences et aux spécifications fonctionnelles. La validation des performances consiste à vérifier que le système est capable de gérer le volume et la variété des données et qu’il est capable de fournir les résultats attendus dans les délais impartis. Enfin, la validation des données consiste à vérifier que les données sont correctement stockées et accessibles dans le système.

Le processus de testing des Data Lakehouses est essentiel pour s’assurer que le système est conforme aux exigences et qu’il fonctionne correctement. Il permet aux organisations d’identifier et de résoudre rapidement tout problème avant la mise en production, ce qui permet d’améliorer la qualité du système et d’accroître sa fiabilité. En outre, le testing permet aux organisations de s’assurer que leurs systèmes sont prêts à être mis en production et qu’ils sont capables de fournir les résultats attendus.

Construire le prochain Data Lakehouse : 10X Performance

Construire le prochain Data Lakehouse pour obtenir une performance 10X plus rapide est un défi passionnant. Nous devons trouver des moyens innovants pour exploiter les technologies de données modernes.

Unification: La Nouvelle Paradigme du Data Lakehouse

unifying data, unifying analytics, and unifying governance.

En tant que scientifique informatique enthousiaste, je peux dire que le concept de data lakehouse est un paradigme révolutionnaire. Il a été défini par Bill Inmon il y a plus de 30 ans comme « une collection intégrée, non volatile et à temps variable de données à des fins de prise de décision ». Cependant, les premiers data warehouses étaient incapables de stocker des données hétérogènes massives, ce qui a conduit à la création des data lakes.

Aujourd’hui, le data lakehouse est une architecture de gestion de données ouverte dotée de puissantes capacités d’analyse et de gouvernance des données, d’une grande flexibilité et d’un stockage ouvert. Si je devais utiliser un seul mot pour décrire le data lakehouse de nouvelle génération, ce serait unification : unifier les données, unifier l’analyse et unifier la gouvernance.

Le data lakehouse est une solution idéale pour les entreprises qui souhaitent tirer parti de leurs données. Il permet aux entreprises d’accéder à des informations précieuses et d’utiliser des outils d’analyse avancés pour prendre des décisions plus éclairées. Grâce au data lakehouse, les entreprises peuvent facilement intégrer des données hétérogènes et obtenir des informations exploitables pour leurs activités. De plus, le data lakehouse offre une meilleure visibilité sur les données et une meilleure sécurité grâce à des fonctionnalités de codage avancées.

En conclusion, le data lakehouse est une solution innovante qui offre aux entreprises une meilleure gestion et une meilleure analyse des données. Il permet aux entreprises de tirer parti de leurs données pour prendre des décisions plus éclairées et améliorer leurs activités. Le data lakehouse est une solution idéale pour les entreprises qui cherchent à intégrer des données hétérogènes et à utiliser des outils d’analyse avancés pour améliorer leurs performances.

Successful data-driven companies like Uber, Facebook, and Amazon rely on real-time analytics. Personalizing customer experiences for e-commerce, managing fleets and supply chains, and automating internal operations require instant insights into the freshest data.

To deliver real-time analytics, companies need a modern technology infrastructure that includes three things:

Data is becoming increasingly crucial for success in the digital economy. You might ask, why do organizations rely so much on data? Well, a majority of organizations rely on data for multiple processes, from product management and fraud detection to HR, finance, and manufacturing. Data analytics allow users to use pre-made reports to track performance metrics on demand. Research shows that 94% of organizations believe that data and analytics solutions are critical for growth. Not a surprising statistic since it offers several benefits, including an increase in productivity and efficiency, faster and more effective decision making, and financial gains!  

Before we dive into the ins and outs of data analytics, it is important to understand the two terms, namely ‘data science’ and ‘data analytics. Data science lays emphasis on finding meaningful correlations between large datasets, while data analytics is a branch of data science designed to uncover specifics of extracted insights

MySQL is the most popular open source cloud database in the world, and for good reason. It’s powerful, flexible, and extremely reliable. Tens of thousands of companies use MySQL to power their web-based applications and services every day.

But when it comes to data analytics, it’s a different story. MySQL is quickly bogged down by even the smallest analytical queries, putting your entire application at risk of crashing. As one FlyData customer said to us, “I have nightmares about our MySQL production database going down.”

The Background

At the base of Carbon’s real-time, first-party data platform is our analytics component, which combines a range of behavioral, contextual, and revenue data, which is then displayed within a dashboard in a series of charts, graphs, and breakdowns to give a visual representation of the most important actionable data. Whilst we pre-calculate as much of the information as possible, there are different filters that allow users to drill deeper into the data, which makes querying critical.

Gartner predicts that by 2023, over 50% of medium to large enterprises will have adopted a Low-code/No-code application as part of their platform development.
The proliferation of Low-code/No-code tooling can be partially attributed to the COVID-19 pandemic, which has put pressure on businesses around the world to rapidly implement digital solutions. However, adoption of these tools — while indeed accelerated by the pandemic — would have occurred either way.
Even before the pandemic, the largest, richest companies had already formed an oligopsony around the best tech talent and most advanced development tools. Low-Code/No-code, therefore, is an attractive solution for small and mid-sized organizations to level the playing field, and it does so by giving these smaller players the power to do more with their existing resources.
While these benefits are often realized in the short term, the long-term effect of these tools is often shockingly different. The promise of faster and cheaper delivery is the catch — or lure — inside this organizational mousetrap, whereas backlogs, vendor contracts, technical debts, and constant updates are the hammer.
So, what exactly is the No-Code trap, and how can we avoid it?

What is a No-Code Tool?

First, let’s make sure we clear up any confusion regarding naming. So far I have referred Low-Code and No-Code as if they were one term. It’s certainly easy to confuse them — even large analyst firms seem to have a hard time differentiating between the two — and in the broader context of this article, both can lead to the same set of development pitfalls.
Under the magnifying glass, however, there are lots of small details and capabilities that differentiate Low-code and No-code solutions. Most of them aren’t apparent at the UI level, leading to much of the confusion between where the two come from.
In this section, I will spend a little bit of time exploring the important differences between those two, but only to show that when it comes to the central premise of this article they are virtually equivalent.

Low-Code vs. No-Code Tools

The goal behind Low-Code is to minimize the amount of coding necessary for complex tasks through a visual interface (such as Drag ‘N’ Drop) that integrates existing blocks of code into a workflow.
Skilled professionals have the potential to work smarter and faster with Low-Code tools because repetitive coding or duplicating work is streamlined. Through this, they can spend less time on the 80% of work that builds the foundation and focuses more on optimizing the 20% that makes it different. It, therefore, takes on the role of an entry-level employee doing the grunt work for more senior developers/engineers.
No-Code has a very similar look and feel to Low-Code, but is different in one very important dimension. Where Low-Code is meant to optimize the productivity of developers or engineers that already know how to code (even if just a little), No-Code is built for business and product managers that may not know any actual programming languages. It is meant to equip non-technical workers with the tools they need to create applications without formal development training.
No-Code applications need to be self-contained and everything the No-Code vendor thinks the user may need is already built into the tool.
As a result, No-Code applications create a lot of restrictions for the long-term in exchange for quick results in the short-term. This is a great example of a ‘deliberate-prudent’ scenario in the context of the Technical Debt Quadrant, but more on this later.

Advantages of No-Code Solutions

The appeal of both Low-Code and No-Code is pretty obvious. By removing code organizations can remove those that write it — developers — because they are expensive, in short supply, and fundamentally don’t produce things quickly.
The benefits of these two forms of applications in their best forms can be pretty substantial:
  • Resources: Human Capital is becoming increasingly scarce — and therefore expensive. This can stop a lot of ambitious projects dead in their tracks. Low-Code and No-Code tools minimize the amount of specialized technical skills needed to get an application of the ground, which means things can get done more quickly and at a lower cost.
  • Low Risk/High ROISecurity processes, data integrations, and cross-platform support are all built into Low-Code and No-Code tools, meaning less risk and more time to focus on your business goals.
  • Moving to Production: Similarly, for both types of tools a single click is all it takes to send or deploy a model or application you built to production.
Looking at these advantages, it is no wonder that both Low-Code and No-Code have been taking industries by storm recently. While being distinctly different in terms of users, they serve the same goal — that is to say, faster, safer and cheaper deployment. Given these similarities, both terms will be grouped together under the ‘No-Code’ term for the rest of this article unless otherwise specified.

List of No-Code Data Tools

So far, we have covered the applications of No-Code in a very general way, but for the rest of this article, I would like to focus on data modeling. No-Code tools are prevalent in software development, but have also, in particular, started to take hold in this space, and some applications even claim to be an alternative to SQL and other querying languages (crazy, right?!). My reasons for focusing on this are two-fold: 
Firstly, there is a lot of existing analysis around this problem for software development and very little for data modeling. Secondly, this is also the area in which I have the most expertise.
Now let’s take a look at some of the vendors that provide No-Code solutions in this space. These in no way constitute a complete list and are, for the most part, not exclusively built for data modeling. 

1. No-Code Data Modeling in Power BI

Power BI was created by Microsoft and aims to provide interactive visualizations and business intelligence capabilities to all types of business users. Their simple interface is meant to allow end-users to create their own reports and dashboards through a number of features, including data mapping, transformation, and visualization through dashboards. Power BI does support some R coding capabilities for visualization, but when it comes to data modeling, it is a true No-Code tool.

2. Alteryx as a Low-Code Alternative

Alteryx is meant to make advanced analytics accessible to any data worker. To achieve this, it offers several data analytics solutions. Alteryx specializes in self-service analytics with an intuitive UI. Their offerings can be used as Extract, Transform, Load (ETL) Tools within their own framework. Alteryx allows data workers to organize their data pipelines through their custom features and SQL code blocks. As such, they are easily identified as a Low-Code solution.

3. Is Tableau a No-Code Data Modeling Solution?

Tableau is a visual analytics platform and a direct competitor to Power BI. They were recently acquired by Salesforce which is now hoping to ‘transform the way we use data to solve problems—empowering people and organizations to make the most of their data.’ It is also a pretty obvious No-Code platform that is supposed to appeal to all types of end-users. As of now, it offers fewer tools for data modeling than Power BI, but that is likely to change in the future.

4. Looker is a No-Code Alternative to SQL

Looker is a business intelligence software and big data analytics platform that promises to help you explore, analyze, and share real-time business analytics easily. Very much in line with Tableau and Power BI, it aims to make non-technical end-users proficient in a variety of data tasks such as transformation, modeling, and visualization.

You might be wondering why I am including so many BI/Visualization platforms when talking about potential alternatives to SQL. After all, these tools are only set up to address an organization’s reporting needs, which constitute only one of the use cases for data queries and SQL. This is certainly a valid point, so allow me to clarify my reasoning a bit more.

While it is true that reporting is only one of many potential uses for SQL, it is nevertheless an extremely important one. There is a good reason why there are so many No-Code BI tools in the market—to address heightening demand from enterprises around the world — and therefore, it is worth taking a closer look at their almost inevitable shortcomings.

Facebook and Twitter have left most other companies around the world far behind when it comes to using machine learning to improve their business model. And while their practices haven’t always resulted in the best reactions from end-users, there’s much to be learned from these companies on what to do–and what not to do–when it comes to scaling and applying data analytics.

Get the Data You Need First

While Facebook seemingly uses machine learning for everything — it is used for content detection and content integrity, sentiment analysis, speech recognition, and fraudulent account detection, as well as operating functions like facial recognition, language translation, and content search functions. The Facebook algorithm manages all this while offloading some computation to edge devices in order to reduce latency.

The need for data engineers and analysts to run interactive, ad hoc analytics on large amounts of data continues to grow explosively. Data platform teams are increasingly using the federated SQL query engine PrestoDB to run such analytics for a variety of use cases across a wide range of data lakes and databases in-place, without the need to move data. PrestoDB is hosted by the Linux Foundation’s Presto Foundation and is the same project running at massive scale at Facebook, Uber and Twitter.

Let’s look at some important characteristics of Presto that account for its growing adoption.
