Mohd Sohel Ather

With data being a valuable instrument in a modern approach to business, its impact on logistics and supply chain management can hardly be overestimated. As enterprises are trying hard to earn more customers and hence gain a competitive edge over their rivals, the need to stay current with global changes causes massive adoption of high technologies within the industry.

In this way, logistics companies are transforming their traditional approach to supply chain management (SCM) based on the power of data. As the supply system is a set of complex stages from the purchase of initial material to delivering a ready-made product to final consumers, it requires effective management and control.

Hence, by integrating data analytics in SCM, companies can analyze figures and make informed business decisions. This leads to optimization and boosting efficiency of crucial supply chain operations and enhanced customer experience.

Besides, data analytics solutions contribute to increased cost effectiveness which is proved by the following estimates: businesses with optimized supply chains reduce supply chain expenditures by 15% and make cash-to-cash cycles 3 times faster. In this event, 79% of companies with effective supply chains have reported above-average revenue growth, as a 2023 survey by Deloitte states.

Thus, this article explains the role of data analytics in optimizing supply chain logistics.


Here’s your roadmap to Data Analysis 101


Data analytics basics for logistics and supply chain management

Analytics, being a core component of supply chain management, processes and assesses vast amounts of data generated within the frames of the entire supply cycle. It collects information from suppliers, dealers, deliverers, warehouses, etc.

As a result of such an analysis, companies gain relevant information and leverage it for making more informed decisions.  The function of real-time performance monitoring allows companies to get insights into order processing time, delivery, and inventory.

The opportunity to observe the relations between these processes helps to identify inefficiencies, detect or foresee any risks, and then take measures for their troubleshooting. 

In this way, one of the most obvious benefits of analytics is its ability to furnish personnel with information that can be applied to optimizing operations, reducing costs, and streamlining the supply network.

Predictive analytics for demand forecasting

Smart analytics tools leveraged in SCM are capable of predicting customer demand based on previous sales data, seasonality, market trends, various economic factors, and others. Estimating future demand for a product or service helps companies regulate procurement, production, and inventories.

Enabling industries with more accurate planning and predictive analytics contributes to risk mitigation and reduction of inventory costs. In this way, AI-powered forecasting offers a way to minimize the need for manual labor and maximize the operational efficiency of business. 

Optimization of inventory management

The ability to respond to ever-changing consumer demands requires having the right products in the right quantity at the right time. Thus, data analytics give insights into the amount of inventory necessary to satisfy the demand without overstocking, outstocking, and product recalling which contributes to reduced operational costs. 

What’s more, smart tools integrated into the supply chain identify the most suitable locations and facilities for storing products. With their help, orders can be filled much more quickly as the goods are sent to the customer’s address from the closest warehouse.

Supplier Relationship Management (SRM)

Well-established cooperation with vendors and suppliers is crucial for the seamless operation of a supply chain. For this reason, businesses adopt SRM models which include a variety of processes from selecting vendors to their performance management and aim at fostering mutually beneficial relationships with them.

Applying analytics in SRM, businesses obtain data that allows assessing the performance and reliability of their suppliers as well as tracing potential risks. The above capabilities of analytics give a detailed overview of all activities associated with SRM and help to identify problem zones to be improved. 

Enhancing customer experience through analytics

Understanding the buying patterns and preferences of customers helps businesses in the choice of their marketing strategies and product offerings. When applied correctly, consumer experience analytics indicate any signals of dissatisfaction and help businesses take necessary steps to minimize buyer churn.

It reflects the way customers interact with products or services and therefore allows for building the right strategy to ensure a personalized experience for buying individuals. Knowledge of customer behavior obtained through smart analysis helps to increase customer loyalty and satisfaction, boost repurchasing rates, and as a result, generate revenue growth. 

Data security and privacy in supply chain analytics

Growing reliance on a data-driven approach to SCM has caused the necessity to enhance the security and protection of sensitive information. Cyber threats and risks of data breaches represent a serious danger for supply chains that contain customer details, product information, pricing, intellectual property, and other confidential data.

To avoid any intervention and unauthorized exploitation of this data, one should implement security measures (encryption, access controls) and maintain their SCM software regularly.




With high technologies evolving day by day, data analytics will become even more important in optimizing supply chain logistics. As seen from the above, integrating this solution in SCM opens up a new way for businesses to perform in the global market. Companies leveraging the power of data in basic and complex operations enhance their efficiency, reduce costs, minimize risks, and ensure an exceptional quality of service to their customers.

MySQL is a popular database management system that is used globally and across different domains. In this article, you will learn more about how it works, where it is used, and how to work with MySQL.

What is MySQL?

MySQL is widely used by web developers and large companies for storing and managing data. It is one of the most popular database management systems (DBMS) globally that supports all major operating systems: Linux, macOS, and Windows.

Databases are stored on a server, which is typically a remote computer or a cloud server. When you need data, you send a query to the server using your computer, or client, and you receive the information. To manage queries, a special language called Structured Query Language (SQL) is used.


Large language model bootcamp

Imagine you have an online clothing store. You need to keep track of all your products, customers, and sales. MySQL can be used for this purpose.

In the DBMS, separate tables are created for products, customers, and sales. The first table stores information about each product, such as its name, price, and available quantity. The second table contains names, contact information, and payment details. The third table holds information about customers who purchased the product, sale dates, and purchased item names.

If you want to know how many sales occurred and who bought products last month, you write a query, send it to the server, and get a list of the relevant data.


Understand the database dilemma of SQL vs NoSQL


MySQL enables storing and processing information, especially crucial when dealing with large amounts of data. A small store with one seller may record everything in an Excel spreadsheet. Still, for a large network with hundreds of daily purchases, this approach becomes inconvenient.

However, MySQL is not only used in retail but in any context where data is involved.

What is SQL?

To communicate with a database, you need to know its language – SQL, which stands for Structured Query Language. Each query must follow a specific structure for the database to understand you.

At the beginning of the query, there is an action – delete, select, add, followed by a keyword indicating from which table to extract information. Further, there is a statement explaining which details and from which cell of the table to retrieve. The query may also include a condition at the end: for example, the action will be performed only under specific circumstances.


Understanding the general query structure for a database management system
Understanding the general query structure for a database management system


Queries are entered through the terminal – for this, you need to download a specific program. With its help, you can create and modify tables, link them, add and delete data, and find what you need.

Here’s an SQL crash course for a beginner to explore.



What is MySQL used for?

With MySQL, you can store any type of data: text, numbers, images, audio and video files, and graphics. Thanks to the system’s performance, even very large volumes of data can be stored, and everything will still function normally. Obtaining the required information can be quick if you know how to use SQL.

MySQL addresses the issue of multiple users when several users are modifying data in the database simultaneously, and only one version is saved. When a user connects to MySQL, the server creates a new entry for them in the metadata table, containing information about the connection state, including the current transaction, if any. This ensures that the data is kept up-to-date.


Here’s a guide to understanding different types of databases


Additionally, MySQL uses a system of locks to control access to data. When a user tries to access a table, MySQL checks if the table is locked by another user. If the table is locked, the user must wait until the lock is released. This prevents data from being overwritten, and nothing is lost.

Different permissions allow server administrators to manage users’ access to various functions and data. For example, access can be granted only to the data necessary for work, enhancing data storage security.

Who uses MySQL?

Here are a few examples of how large companies use MySQL:

Tesla uses MySQL to store and process data about its cars, including battery status, mileage, speed, and other parameters. MySQL allows Tesla to quickly access this data and analyze it to improve the performance and safety of their cars.

Netflix stores data about its users, such as viewing history, preferences, and recommendations, using a DBMS. This tool helps the company improve its recommendations and personalize content.

PayPal utilizes MySQL to collect and store transaction information, using this data to enhance the security and efficiency of payments.

Essentially, MySQL can be applied in any application or web service, be it an online cinema, a store, a blog, or social network.

Advantages of MySQL

These advantages make MySQL one of the most popular and widely used database management systems in the world:

  • It is free to use; MySQL has open-source code.
  • No need to worry about performance; MySQL is optimized to handle a large number of queries.
  • No need to worry about data; MySQL supports backup and restoration mechanisms that ensure data integrity.
  • Applications are easily expandable; MySQL supports various data storage types, table engines (such as InnoDB, and MyISAM), and other features that enable developers to create complex applications.

How is the MySQL database management system structured?

MySQL consists of several components, each serving specific functions:

  • The main component manages all database operations. The MySQL server receives requests from clients, processes them, performs necessary data operations, and returns the results to clients.
  • Mysqld Service. A process running on the server responsible for managing databases. It accepts requests from clients, processes them, performs read and write data operations, manages transactions, and ensures data security.
  • Data Storage. MySQL uses various types of data storage, such as InnoDB, MyISAM, MEMORY, and others, each with specific features designed for certain data types or tasks.
  • Client Applications. Various client applications, such as MySQL Workbench, phpMyAdmin, the MySQL command-line interface, and others, are used to work with MySQL. These applications allow administrators and developers to create, modify, and manage databases through graphical or text interfaces, such as the terminal.

In this blog, we’re diving into a new approach called rank-based encoding that promises not just to shake things up but to guarantee top-notch results.


Rank-based encoding – a breakthrough?


Say hello to rank-based encoding – a technique you probably haven’t heard much about yet, but one that’s about to change the game.


rank-based encoding
An example illustrating rank-based encoding – Source: ResearchGate


In the vast world of machine learning, getting your data ready is like laying the groundwork for success. One key step in this process is encoding – a way of turning non-numeric information into something our machine models can understand. This is particularly important for categorical features – data that is not in numbers.


Join us as we explore the tricky parts of dealing with non-numeric features, and how rank-based encoding steps in as a unique and effective solution. Get ready for a breakthrough that could redefine your machine-learning adventures – making them not just smoother but significantly more impactful.


Problem under consideration


In our blog, we’re utilizing a dataset focused on House Price Prediction to illustrate various encoding techniques with examples. In this context, we’re treating the city categorical feature as our input, while the output feature is represented by the price.


Large language model bootcamp


Some common techniques


The following section will cover some of the commonly used techniques and their challenges. We will conclude by digging deeper into rank-based encoding and how it overcomes these challenges.


  • One-hot encoding  


In One-hot encoding, each category value is represented as an n-dimensional, sparse vector with zero entries except for one of the dimensions. For example, if there are three values for the categorical feature City, i.e. Chicago, Boston, Washington DC, the one-hot encoded version of the city will be as depicted in Table 1.


If there is a wide range of categories present in a categorical feature, one-hot encoding increases the number of columns(features) linearly which requires high computational power during the training phase.  


City  City Chicago  City Boston  Washington DC 
Chicago  1  0  0 
Boston  0  1  0 
Washington DC  0  0  1 

  Table 1 


  • Label encoding  


This technique assigns a label to each value of a categorical column based on alphabetical order. For example, if there are three values for the categorical feature City, i.e. Chicago, Boston, Washington DC, the label encoded version will be as depicted in Table 2.


Since B comes first in alphabetical order, this technique assigns Boston the label 0, which leads to meaningless learning of parameters.  


City  City Label Encoding 
Chicago  1 
Boston  0 
Washington DC  2 

Table 2 


  • Binary encoding  


It involves converting each category into a binary code and then splitting the resulting binary string into columns. For example, if there are three values for the categorical feature City, i.e. Chicago, Boston, Washington DC, the binary encoded version of a city can be observed from Table 3.


Since there are 3 cities, two bits would be enough to uniquely represent each category. Therefore, two columns will be constructed which increases dimensions. However, this is not meaningful learning as we are assigning more weightage to one category than others.


Chicago is assigned 00, so our model would give it less weightage during the learning phase. If any categorical column has a wide range of unique values, this technique requires a large amount of computational power, as an increase in the number of bits results in an increase in the number of dimensions (features) significantly. 


City  City 0  City 1 
Chicago  0  0 
Boston  0  1 
Washington DC  1  0 

  Table 3 


  • Hash encoding  


It uses the hashing function to convert category data into numerical values. Using hashed functions solves the problem of a high number of columns if the categorical feature has a large number of categories. We can define how many numerical columns we want to encode our feature into.


However, in the case of high cardinality of a categorical feature, while mapping it into a lower number of numerical columns, loss of information is inevitable. If we use a hash function with one-to-one mapping, the result would be the same as one-hot encoding. 


  • Rank-based Encoding: 


In this blog, we propose rank-based encoding which aims to encode the data in a meaningful manner with no increase in dimensions. Thus, eliminating the increased computational complexity of the algorithm as well as preserving all the information of the feature.


Rank-based encoding works by computing the average of the target variable against each category of the feature under consideration. This average is then sorted in decreasing order from high to low and each category is assigned a rank based on the corresponding average of a target variable. An example is illustrated in Table 4 which is explained below:


The average price of Washington DC = (60 + 55)/2 = 57.5 Million 

The average price of Boston = (20 +12+18)/3 = 16.666 Million 

The average price of Chicago = (40 + 35)/2 = 37.5 Million


In the rank-based encoding process, each average value is assigned a rank in descending order.


For instance, Washington DC is given rank 1, Chicago gets rank 2, and Boston is assigned rank 3. This technique significantly enhances the correlation between the city (input feature) and price variable (output feature), ensuring more efficient model learning.


Learn to build LLM applications


In my evaluation, I assessed model metrics such as R2 and RMSE. The results demonstrated significantly lower values compared to other techniques discussed earlier, affirming the effectiveness of this approach in improving overall model performance. 


City  Price  City Rank 
Washington DC  60 Million  1 
Boston  20 Million  3 
Chicago  40 Million  2 
Chicago  35 Million  2 
Boston  12 Million  3 
Washington DC  55 Million  1 
Boston  18 Million  3 

Table 4 




We summarize the pros and cons of each technique in Table 5. Rank-based encoding emerges to be the best in all aspects. Effective data preprocessing is crucial for the optimal performance of machine learning models. Among the various techniques, rank-based encoding is a powerful method that contributes to enhanced model learning.


Rank-based encoding technique facilitates a stronger correlation between input and output variables, leading to improved model performance. The positive impact is evident when evaluating the model using metrics like RMSE and R2 etc. In our case, these enhancements reflect a notable boost in overall model performance.

Are Data Analysts in demand in 2023?  

The world is generating more data than ever before. In fact, it is estimated that by 2025, the global datasphere will be 175 zettabytes in size. This data is being generated by everything from our smartphones to our smart homes to our cars 

As the amount of data grows, so does the need for data analysts. Data analysts are responsible for collecting, cleaning, and analyzing data to extract insights. These insights can then be used to improve business decisions, optimize operations, and develop new products and services.  

The demand for data analysts is expected to continue to grow in the years to come. In fact, a recent report by the World Economic Forum found that data and AI is one of the seven high-growth emerging professions.

Types of data in marketing 

Data is like the language your customers use to speak to you, and there are different ‘dialects you need to be fluent in. Here are the primary types of data used in marketing: 

  • Demographic data: This type of data includes basic information about your customers such as age, gender, location, income, and occupation. It helps businesses understand who their customers are.
  • Psychographic data: This is a step deeper. It involves understanding your customers’ attitudes, interests, lifestyles, and values. It paints a picture of why your customers behave the way they do.
  • Behavioral data: This includes purchasing behaviors, product usage, and interactions with your brand. It gives you a peek into what your customers do.
  • Feedback data: This comes directly from your customers via reviews, surveys, and social media. It shows how your customers perceive your brand.

All these types of data, when analyzed and understood, provide rich, nuanced insights about your customer base. It’s like assembling a jigsaw puzzle where every piece of data adds more detail to the picture.   

Techniques in data analysis 

Now, let’s get our hands a little dirty and dig into some common techniques used in data analysis: 

  • Descriptive Analysis: This involves understanding past trends and behaviors. It answers the question, “What happened?”
  • Diagnostic Analysis: This dives deeper into why something happened. It’s like a post-mortem that helps identify the causes of a particular outcome.
  • Predictive Analysis: As the name suggests, this technique is all about forecasting future trends and behaviors based on past data.
  • Prescriptive Analysis: This is the most advanced form of data analysis. It suggests courses of action to take for future outcomes.

Using these techniques, marketers can transform raw data into actionable insights. It’s quite similar to a cook turning raw ingredients into a delicious meal!

Data analysis tools: The magic wand for marketers 

In our data-driven world, numerous tools help marketers analyze and interpret data. These tools are like magic wands, transforming data into visually appealing and easily understandable formats. 

  • Google Analytics: It provides insights into website traffic, user behaviors, and the performance of online marketing campaigns.

The Power of A/B Testing 

Now, here’s something particularly exciting! Have you ever found yourself torn between two options, unable to decide which is better? Well, in marketing, there’s a fantastic way to make that decision – A/B testing! 

A/B testing, also known as split testing, is a method to compare two versions of a web page, email, or other marketing asset to see which performs better. It’s a practical, straightforward way to test changes to your marketing campaigns before implementing them. 

For instance, if you’re not sure whether a green or a red button will drive more clicks on your website, simply test both versions. The one that garners more clicks wins! It’s that simple, and it’s all thanks to the science of data analysis. 

Bringing it all together 

So, there you have it! We’ve taken a whirlwind tour through the fascinating world of data-driven marketing. But, as they say, the proof of the pudding is in the eating.

Remember, in our digital age, data isn’t just a byproduct; it’s a vital strategic asset. So, here’s to harnessing the power of data analysis for more effective, efficient, and successful marketing campaigns. Cheers!
