Sentiment score
6.7
erwin Data Modeler excels in scalability and flexibility, but complex schemas may impact performance; licensing supports user expansion.

Segment is highly scalable for events and integrations, but data changes and licensing costs can limit flexibility.
I would rate it probably a nine, making it a leader in data modeling.

Stability Issues

Sentiment score
6.5
Erwin Data Modeler is reliable with stability issues mainly in large models, lacking auto-save, but updates improve performance.

Room For Improvement

Erwin Data Modeler needs UI, collaboration, NoSQL support, integration, and performance improvements for large models and impact analysis.
Segment faces challenges with complex integrations, SDK flexibility, identity management, scalability, learning curve, and AI-driven marketing automation.
The previous version of erwin Data Modeler used to crash unaccountably, but this one hasn't ever crashed on me, so it's been a lot more stable than the previous version that we had.
Data Warehouse Architect at a healthcare company with 10,001+ employees
There is room for improvement in its AI capabilities, such as automatically suggesting normalization or identifying primary, foreign, or surrogate keys to make modeling more efficient.
Data Specialist at TCS
There are many features, and I would expect good documentation detailing each feature, including when and how to use it, to be very useful because data modeling is not very popular in the data area and there aren't many educational videos regarding erwin Data Modeler.
Senior Data Scientist at a consultancy with 10,001+ employees
More flexibility in pricing models or clear scaling options would make it easier for mid-sized companies to expand usage without significant budget concerns.

Setup Cost

Erwin Data Modeler offers flexible licenses and robust features, though pricing and management complexity may require third-party help.
Segment pricing is high but justified by value, offering savings and scalability for growing enterprises, less so for small businesses.
For a cloud or SaaS standard edition, it typically runs around two hundred to two hundred ninety-nine US dollars per month.
Snowflake Data Engineer| Senior PLSQL Developer |Data Modeler|Assitant Vice Pre at Jp Morgan Chase & Co.
The experience with pricing, setup cost, and licensing is that the licensing process is painful and quite onerous.
Contract Data Architect at a financial services firm with 10,001+ employees
It is more targeted toward an enterprise level since organizations looking to store business information and relationship values may consider the pricing.
Data Modeler at Capgemini
revealing that Segment is much cheaper, particularly regarding premium licensing.
Data Manager API at a tech vendor with 51-200 employees
It is relatively cheap and very useful at that price point.

The cost is very high, but it is worth it.

Valuable Features

Erwin Data Modeler offers visual data representation, collaborative centralized models, integration, and efficient data management for compliance and communication.
Segment offers streamlined data integration, AI-driven automation, audience building, and enhanced data management for improved decision-making and engagement.
One of the key aspects of data governance is defining the data dictionary and clearly identifying which data is accessible by whom and what is not accessible, particularly regarding PII-related data.
SPM at Infosys
The way the data is organized and you have a visual of that organization helps a great deal in terms of trying to remember what you did and trying to retrieve the information.
Data Metrics Engineer at a financial services firm with 10,001+ employees
Migrating DDLs using erwin Data Modeler is easy because I just connect to the database and generate the data model from what is already implemented, making the process straightforward.
Data Modeler at FNB Mozambique
I think predictive audiences require a 360 view of the customer in order to create these types of AI audiences because they use a lot of different data points.
Web and marketing automation specialist at a logistics company with 5,001-10,000 employees
Segment has improved our data quality and our ease of collection, and most importantly, it has saved us time by not having to maintain a custom tool for server-side tracking.

Sushree Panigrahi - PeerSpot reviewer
Snowflake Data Engineer| Senior PLSQL Developer |Data Modeler|Assitant Vice Pre at Jp Morgan Chase & Co.
Data modeling has transformed regulatory reporting and collaboration across cloud environments
In erwin Data Modeler, areas that have room for improvement include performance improvements. I see that large models sometimes cause it to be slow when opening. Impact analysis can lag as well. Version control is another aspect. If we have developed a current version, it is not integrated with Git where we can easily compare different versions. UI modernization is also something we cannot utilize as it is primarily for development. Additionally, cloud-specific optimizations are needed when it comes to Snowflake or Databricks. When it comes to AI aspects, auto-suggestions for normalization or identifying primary, foreign, or surrogate keys are areas that can be improved.

Behavioral insights have powered personalized investor journeys and data-driven campaigns
I have not used Segment for more than a year, so I am not aware of its current evolution, but I know there was a migration from Segment to Adobe as a strategic decision by XP bank, which pointed out unified databases as an improvement area compared to Segment, where they effectively utilized AI for creative marketing campaign generation. The necessary improvements in Segment based on my experience focus on providing more tools for the marketing team, particularly using AI to create campaigns through images and short videos, enhancing communication with end customers via offer banners in a more automated and effective manner.
