Data modeling vs. data analysis: A breakdown of their differences


What’s the difference between data modeling and information analysis? Which is the ideal approach for your next project? This guide helps address those concerns.

Simply put, data analysis has to do with utilizing data and info to drive company decisions, while information modeling refers to the architecture that makes analysis possible. To put it simply, information modeling and information analysis work best when they are utilized together.

But how do organizations embed data into every choice and procedure? The answer starts with reliable data modeling and continues with data analysis. Let’s compare the two principles below and learn how overlapping them can benefit your company.

What is information modeling?

Data modeling is an information technique that concentrates on transforming raw data into structural, frequently graphes that help experts obtain more significant insights from the data.

Data modeling seeks to map out the types of data your organization uses and where it is kept within systems. Additionally, it shows relationships in between information types and discovers methods to group and organize information by establishing formats and characteristics.

“An information design can be compared to a roadmap, a designer’s plan or any formal diagram that facilitates a much deeper understanding of what is being developed,” analysts from IBM stated.

Companies need to construct models around organization requirements, equate business needs into data structures, develop concrete database styles and be prepared to evolve as businesses change.

Types of data modeling

These are the 3 most common data model types:

Must-read big information coverage

  • Relational model: Shops information in fixed-format records and sets up information in tables with rows and columns. Standard relational approaches define raw data as a step or a dimension.
  • Dimensional model: Less rigid and structured, the dimensional approach prefers a contextual data structure associated to organization use or context. This database structure is optimized for online questions and information warehousing tools.
  • Entity-rich model: These are formal diagrams that represent relationships in between entities in a database. IBM describes that information architects utilize a number of ER modeling tools to develop visual maps that communicate database style objectives.

The 3 levels of information abstraction

  • Conceptual information model: The vision or roadmap. This layer represents the general structure. This is where data modeling typically begins by recognizing information sets and data flow through the organization.
  • Logical data model: This is the second layer of abstraction and goes into more detail about the information design. It outlines information circulation and database content.
  • Physical data design: This layer defines how the logical model will be applied to the real data set. Utilizing this layer, IT groups develop the genuine database structure, as well as the software and hardware, to support the plan. Multiple physical designs can be derived from a single rational design if different database systems are used.

What is information analysis?

Information analysis is a holistic information method that includes examining, analyzing, cleaning, transforming, moving and modeling data to draw out beneficial details for internal and external service goals. While data modeling produces the architecture that helps data groups derive valuable data insights, data analysis actually puts the model in motion and leverages data to drive outcomes.

A few of the most common data analysis approaches consist of:

  • Analytical analysis
  • Inferential analysis
  • Diagnostic analysis
  • Data mining
  • Predictive analysis
  • Prescriptive analysis

The information analysis procedure

  • Setting concerns, goals and targets: Companies that are first starting their information analysis journeys normally begin by asking what issue they are attempting to fix. What are business objectives surrounding information analysis efforts?
  • Collecting raw information: Organizations relocate to collect raw data that might answer those questions or assistance progress towards conference data-driven targets.
  • Information cleansing: Information is cleaned up and looked for quality, guaranteeing the data is “fit for business use.” This suggests the data should have no duplicates, anomalies, or inconsistencies; be safe; and be properly formatted.
  • Information analysis: Once information is cleaned up, it is analyzed to try to find data patterns, trends and relationships. Analysts should try to find chances and threats in the data at this time. Information analysis tools consist of Excel, Python, R, Looker, Rapid Miner, Chartio, Metabase, Redash and Microsoft Power BI.
  • Information analysis: Data analysis outcomes are interpreted and presented to anybody working on data-driven jobs in the company. Results are likewise confirmed at this stage.
  • Information visualization: Data visualizations or presentations use charts, charts, maps, bullet points and a host of other techniques to deliver easy-to-understand insights to a range of company stakeholders.

The main differences in between data modeling and data analysis

Information modeling and analytics are both integral to information management and data-driven operations. Organizations on an information change journey can pass by one over the other but have to participate in both principles to totally establish data architectures and use their data to enhance their operations.

As mentioned, data modeling is the roadmap and blueprint that is utilized to construct the hardware and software where databases will be linked. Then, information analysis enters into play once the design is built and is strictly worried about using that data to enhance decision-making. It depends on the infrastructure that information modeling offers, but information analysis itself is not concerned with altering data infrastructure.

For efficient data-driven companies, data modeling and data analysis share a lot of common ground. They should both be lined up with business objectives and top priorities. Furthermore, both are part of a strong information culture. When they are utilized together, business can serve customers much better, boost sales, make much better decisions, meet governance and privacy standards, and ultimately back up all service choices with higher-quality information.
