New adventures are around the corner. Wishing you and all of your loved one\’s health and happiness in the new year. May you have a year filled with health and prosperity in every aspect. 

For those of you new here, this is Jordan from SnapStack Solutions, and every Friday I am coming forward with an interesting article coming from the wondrous world of IT. 

This week, as the topic suggests, we will be talking about databases. 

It\’s not always straightforward to pick the best database for storing your data. In reality, while using a relational database may appear more intuitive at first, it may not be the best option in some circumstances.

In this article, I\’ll try to explain the distinctions between relational and non-relational databases, as well as their benefits and drawbacks.

Information maintained by businesses and organizations is not retained in a disorganized and unstructured manner. Organizational data, on the other hand, almost usually follows a set of rules that dictate how information is categorized, how new data received into the system interacts with old data, and how information is retrieved when it is needed in another system.

A database is a technology that handles the functions of storing information and serving it up when needed. Databases are an important part of any information ecosystem.

Relational Databases

A Relational Database is a collection of elements that have pre-defined relationships between them. All of the objects are arranged in tables, with columns representing the qualities of each item. A single data item is represented by each row in a table.

A primary key should be established for each table in order to uniquely identify each item in the table. One or more table columns might be included in a primary key. Different foreign keys might link many tables together.

Without changing the table architecture, a Relational Database might be queried in a variety of ways. The most well-known interface for communicating with a Relational Database is the Structured Query Language (SQL).

Here are some examples of relational databases: MySQL, Postgres, Microsoft SQL Server, SQLite.

To summarize, all information in a Relational Database is structured, i.e. it is organized in tables.

The Benefits of Relational Databases

– Ideal for structured data.

– Utilization of a pre-existing query language (SQL)

– Excellent for more complicated inquiries.

– Data navigation is simple.

– Due to linkages and restrictions across tables, there is a high level of data integration.

– The transactions are safe.

– Exceptional reliability

The Drawbacks of Relational Databases

– Schema definition upfront

– No adaptability to changing requirements: dynamic changes to one item have an impact on all other items in the table.

– It\’s possible that data processing will be sluggish. With pricey gear, high performance is feasible.

When should a relational database be used?

Data with a rather solid structure that lends itself to rows and columns are best stored in relational databases. Data points having a consistent meaning, that can be simply classified, and that have easily defined connections are ideal candidates for storing in a relational database.

The following are some examples of data models that are well suited for relational databases:

– Internal records and employee data

– History of purchases

– Analytical tools for websites and apps

– Individual user events 

– Financial records

Non Relational Databases

A non-relational database is a collection of unstructured, structured, or semi-structured elements that are often represented as key-value pairs. Every item in the collection may be a document, a table, or something else.

Distinct objects in the same or different collections are usually unrelated, however, a reference (such as an identifier) can be added to one to refer to another.

The following are some examples of non-relational database engines: Apache, Cassandra, Redis, Couchbase, Apache, HBase, MongoDB. To summarize, non-tabular databases store data in a non-table format.

The Advantages of Non-Relational Databases

– Adaptable Data model

– Rapid response to changing requirements: dynamic adjustments to one item have no impact on the other.

– Massive amounts of data are stored with little organization.

– Exceptional performance

The Drawbacks of Relational Databases

  • Schema definition upfront
  • No adaptability to changing requirements: dynamic changes to one item have an impact on all other items in the table.
  • It\’s possible that data processing will be sluggish.

With pricey gear, high performance is feasible.

When is a non-relational database appropriate?

Because they can store a broad variety of data types, including big texts, non-relational databases are seen to be more versatile than relational databases. They are particularly suited to use scenarios when you have a big amount of data linked to a specific issue that you expect to develop in size and complexity due to their flexibility. These may include the following:

– Customer profiles that are all the same

– Segments of the audience

– Databases for applications

– Text, photos, and other material in large collections

– Data on industry trends

Summary

I\’ve discussed the advantages and disadvantages of relational and non-relational databases in this post. If your ultimate objective is to identify patterns and significance in various types of data, a non-relational database might be advantageous in analytics use cases. Because new data does not have to correspond to the data types of existing data, NoSQL databases allow for more flexible expansion than relational databases. 

However, accessing non-relational databases has a steeper learning curve and sometimes necessitates a greater commitment of technical resources than querying relational databases. Having a big internal semi- or non-structured NoSQL database will almost certainly need the hiring of a data science team to maintain, query, and analyze it.

Speaking of hiring a team, or getting the fit resources, at SnapStack Solutions we have the right capacities available and ready to take upon a new challenge. Reach us out on social media, or write us at contact@snapstack.com and we would be more than happy to assist you.

Have a good one! Jordan

The shift towards skills-based hiring: A new era of talent acquisition

In today’s fast-evolving job market, there’s a growing trend towards skills-based hiring, which places a stronger focus on a candidate’s practical abilities rather than traditional qualifications like degrees or titles. This shift is fundamentally changing how companies approach recruitment, resulting in more dynamic and diverse workforces.

Organizations are increasingly recognizing that skills-based hiring can lead to better job performance, role fit, and inclusivity, which is driving widespread adoption of this model.

What is skills-based hiring?

Skills-based hiring is a recruitment strategy where employers focus on a candidate’s specific skills and competencies rather than their formal education or past job titles. For instance, companies may prioritize technical skills, such as proficiency in certain programming languages or software, or soft skills like communication and problem-solving, over traditional criteria like a four-year degree. As noted by SHL, this approach allows companies to uncover hidden talent and focus on candidates’ potential, helping organizations foster diversity, equity, and inclusion.

Why skills-based hiring is gaining popularity

  1. Access to a wider talent pool
    Traditional hiring methods often exclude individuals who may not have formal degrees but possess valuable skills. By adopting skills-based hiring, companies can tap into non-traditional talent pools, including self-taught professionals and those from different socio-economic backgrounds. As Workable reports, nearly 45% of companies in 2024 are expected to drop degree requirements for many roles.
  2. Improved role fit and performance
    Skills-based hiring often leads to a better match between the candidate and the job. Focusing on specific, measurable skills means that employees are more likely to succeed in their roles from day one. According to BCG, hiring based on skills is five times more likely to predict job performance than hiring based solely on degrees. By assessing candidates based on real-world competencies, employers can ensure a higher level of job readiness and productivity.
  3. Fostering lifelong learning and agility
    As companies face rapid technological changes, employees need to continuously upskill to remain relevant. A skills-based approach promotes a culture of lifelong learning, encouraging employees to focus on acquiring new competencies rather than relying on outdated credentials. This mindset aligns with the needs of industries such as IT and digital marketing, where practical skills and staying current with trends are crucial .
  4. Reducing bias and increasing diversity
    Traditional hiring processes can unintentionally reinforce biases related to education or socio-economic background. By shifting the focus to skills, companies can reduce these biases, offering more opportunities to underrepresented groups. According to SHL, a skills-based model promotes inclusivity by leveling the playing field, making it easier for companies to create a diverse workforce.

The challenges of implementing skills-based hiring

While the benefits of this approach are clear, there are several challenges that companies must navigate when adopting skills-based hiring practices.

  1. Defining clear skills criteria
    One of the main challenges is defining the precise skills required for each role. Companies must shift from focusing on traditional job descriptions to crafting skills-based profiles that clearly outline the necessary competencies.
  2. Effective skills assessment
    Assessing a candidate’s skills is often more complex than verifying their educational background. Companies must rely on practical assessments, such as tests or simulations, to evaluate real-world capabilities. For example, Boeing created an apprenticeship program for cybersecurity roles that doesn’t require a degree but emphasizes hands-on learning and skill development (
    McKinsey & Company) (BCG Global).
  3. Cultural change within organizations
    Shifting from a qualifications-based hiring approach to one focused on skills may require a significant cultural change. Long-standing hiring practices can be difficult to overhaul, and companies must invest in training hiring managers and redesigning recruitment processes to fully embrace skills-based assessments.

How companies can make the shift

  1. Invest in skills assessment tools
    Organizations need reliable tools to accurately assess candidates’ skills. Platforms offering practical evaluations, coding challenges, or case studies can help measure relevant abilities in a fair and transparent manner. As SHL highlights, using data-driven assessments allows companies to objectively evaluate competencies, improving hiring outcomes.
  2. Promote upskilling and internal mobility
    Fostering a culture of continuous learning is essential for the future workforce. Companies that encourage employees to reskill and grow within the organization can fill talent gaps internally. BCG notes that employees hired through skills-based hiring often experience longer tenures and are promoted at rates similar to those hired based on degrees.

How do we see it?

The shift toward skills-based hiring is more than just a trend; it represents a fundamental change in how organizations view talent acquisition. As businesses prioritize practical skills and competencies over traditional qualifications, they can build more dynamic, diverse, and high-performing teams. While there are challenges, including defining clear skills criteria and developing effective assessments, the long-term benefits of this approach make it a valuable strategy for future-proofing the workforce.

This approach is not only more inclusive and adaptable but also positions companies to better meet the demands of a rapidly changing job market. As SHL, BCG, McKinsey&Company and other industry leaders have demonstrated, skills-based hiring is key to unlocking hidden talent and ensuring long-term organizational success (McKinsey & Company).

Streamline your recruitment efforts with RPO: The key to efficiency and cost-effectiveness

Are you struggling to manage your recruitment processes effectively? If so, Recruitment Process Outsourcing (RPO) could be the solution you need. RPO is a preferred method for many companies due to its numerous advantages in optimizing recruitment and enhancing efficiency. This approach not only helps in acquiring new employees but also offers a comprehensive understanding of your company's operations and builds strong relationships with hiring managers.

What is Recruitment Process Outsourcing (RPO)?

Recruitment Process Outsourcing (RPO) is a strategic partnership where an external provider manages part or all of the recruitment process for a company. Unlike traditional recruitment, RPO involves a deeper integration with the company's teams, leading to a more efficient and streamlined process. Here’s why RPO stands out:

Direct access and quick feedback

In a traditional recruitment setup, recruiters often face communication discrepancies and delays when dealing with multiple hiring managers. They might be dismissed with vague responses like "I don't have time now," which hampers their efficiency. With RPO, you'll have direct access to hiring teams and can address their needs promptly. This leads to:

  • Reduced delays in candidate evaluation.
  • Quick and precise feedback on potential hires.
  • Efficient recruitment process with fewer obstacles.

Added value and efficiency

One of the main advantages of RPO is the added value it provides. RPO recruiters work closely with hiring managers to understand their specific needs and requirements. This results in:

  • Reduced time-to-fill vacant positions.
  • Increased efficiency in candidate selection.
  • Improved accuracy in hiring decisions.

Financial benefits

From a financial perspective, RPO can be more cost-effective compared to traditional recruitment methods. The cost benefits include:

  • Reduced recruitment costs due to streamlined processes.
  • Lower time-to-hire, which saves money.
  • Cost comparison data in our presentation (see slide no. 4) illustrates the percentage by which RPO can be cheaper than traditional methods.

Additional benefits of Recruitment Process Outsourcing (RPO)

RPO offers several other benefits that contribute to overall recruitment success:

  • Saves time for your internal team by handling the recruitment process and communication.
  • Eliminates the need for an internal recruiter.
  • Assists in setting up efficient recruitment processes.
  • Trains team leaders to enhance recruitment practices.
  • High motivation from RPO recruiters to make successful placements.
  • Improved candidate experience, as candidates interact with a dedicated representative rather than multiple agencies.
  • Enhanced market impression with a single point of contact for candidates.

Conclusion

If you want to recruit efficiently, reduce costs, and enhance your company's competitive edge in the coming year, consider adopting Recruitment Process Outsourcing (RPO). This strategy not only streamlines the recruitment process but also brings significant financial and operational benefits.

Ready to transform your recruitment process? Explore the advantages of RPO and see how it can elevate your company's efficiency and effectiveness.
