SSIS MatchUp Component is Amazing

- Scalability is a limitation as it is single threaded. You can bypass this limitation by partitioning your data (say by alphabetic ranges) into multiple dataflows but even within a single dataflow the tool starts to really bog down if you are doing survivorship on a lot of columns. It's just very old technology written that's starting to show its age since it's been fundamentally the same for many years. To stay relavent they will need to replace it with either ADF or SSIS-IR compliant version. - Licensing could be greatly simplified. As soon as a license expires (which is specific to each server) the product stops functioning without prior notice and requires a new license by contacting the vendor. And updating the license is overly complicated. - The tool needs to provide resizable forms/windows like all other SSIS windows. Vendor claims its an SSIS limitation but that isn't true since pretty much all SSIS components are resizable except theirs! This is just an annoyance but needless impact on productivity when developing new data flows. - The tool needs to provide for incremental matching using the MatchUp for SSIS tool (they provide this for other solutions such as standalone tool and MatchUp web service). We had to code our own incremental logic to work around this. - Tool needs ability to sort mapped columns in the GUI when using advanced survivorship (only allowed when not using column-level survivorship). - It should provide an option for a procedural language (such as C# or VB) for survivor-ship expressions rather than relying on SSIS expression language. - It should provide a more sophisticated ability to concatenate groups of data fields into common blocks of data for advanced survivor-ship prioritization (we do most of this in SQL prior to feeding the data to the tool). - It should provide the ability to only do survivor-ship with no matching (matching is currently required when running data through the tool). - Tool should provide a component similar to BDD to enable the ability to split into multiple thread matches based on data partitions for matching and survivor-ship rather than requiring custom coding a parallel capable solution. We broke down customer data by first letter of last name into ranges of last names so we could run parallel data flows. - Documentation needs to be provided that is specific to MatchUp for SSIS. Most of their wiki pages were written for the web service API MatchUp Object rather than the SSIS component. - They need to update their wiki site documentation as much of it is not kept current. Its also very very basic offering very little in terms of guidelines. For example, the tool is single-threaded so getting great performance requires running multiple parallel data flows or BDD in a data flow which you can figure out on your own but many SSIS practitioners aren't familiar with those techniques. - The tool can hang or crash on rare occasions for unknown reason. Restarting the package resolves the problem. I suspect they have something to do with running on VM (vendor doesn't recommend running on VM) but have no evidence to support it. When it crashes it creates dump file with just vague message saying the executable stopped running.

Automated data monitors have reduced noise initially but have greatly boosted data trust

I love the end-to-end lineage, which I rely on most because when an alert fires, I can trace it from the downstream table back through the dbt models to the exact upstream source in a couple of clicks, which has helped cut our root cause investigation time from hours to minutes. I also love the automated monitors which help us instead of handwriting freshness and volume checks for hundreds of Snowflake tables, the machine learning-based detectors learn normal patterns and alert us on anomalies automatically.On the user interface and user experience, the incident view and Slack alerting keep the whole data team in the loop without anyone having to log in and dig around. The user interface is very good, which Monte Carlo is always known for. Integrations are good, at least for the options we use in our organization. Performance is good. The pricing is a little expensive compared to other alternatives like DataDog, but it is manageable for a product-based company like us. Support has always been proactive and very responsive. Auto intelligence helps detect the right frequency for data refresh. Overall, the customer support is very responsive and helpful 24/7.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Melissa Data is cost effective and efficient."

"Initial setup was fairly straightforward. The documentation was very good in terms of how to integrate and consume the service(s) that we use. It did not take an abundance of time to set up things on our side to use the service."

"Be confident that the scalability and load are not going to be an issue with the services. "

"I believe the Melissa Data products are very good."

"We ran a standard name, address, and zip code, internal dedupe between the different files we had purchased, and we were able to quickly notify our vendor that they had tens of thousands of duplications that they were not even aware of."

"We handle large amounts of data, in the terabytes, and it's important to be able to have a program that can handle that large amount of data at one time and effectively do internal dedupes of the data itself."

"I was able to dedupe millions of records in the past, and append the most recent email."

"Personator application was able to append emails, new address if moved, phone number, geocode, and also standardizes existing customer information."

More Melissa Data Quality pros

"Since using Monte Carlo, the freshness of our data has improved a lot from less than eighty percent to above ninety percent and there has been significant time saved, noting that while we do not keep a precise record of this, there is a steep decrease in time consumed on monitoring and related activities."

"Overall, Monte Carlo has had a very positive impact in terms of having healthier data and being able to trace through the data lineage to understand where exactly in the data life cycle things are going wrong."

"Monte Carlo monitors data quality issues and helps identify and fix those issues efficiently."

"My advice for others looking to use Monte Carlo is to definitely go for it because it is quite useful, accurate, and saves a significant number of hours."

"If a particular project's testing alone takes 120 hours, it is reduced by three-fourths most of the time, which is extremely useful for us."

"Monte Carlo saves me roughly 30% to 40% of my time in doing verifications or data quality checks."

"Monte Carlo has many advantages compared to other solutions, as it has a lot of machine learning functionality and excellent user friendliness, with a crisp interface and good appearance that allows you to onboard any user at any time, and they can easily understand how to use the tool."

"I have never noticed something which Monte Carlo flagged that was not relevant to the issue."

Cons

"An area for improvement is where an end customer's address is not found in the Melissa Data database, even though it is a valid address."

"One thing I would want to have, when you're doing a property search, you can do it either on the FIPS in the APN number or the address itself. For some entries, I'll have the APN number, and some I'll have the address. Apparently it cannot process something when both the FIPS-APN and the address are on there. I have to sort, once with one and once with the other, which is a little bit of a pain."

"Needs to validate more addresses accurately."

"MatchUp is a more complex product and I recommend a test area before upgrading to production. Performance can change from version to version."

"The use case I'm familiar with is for a merchant who was contrasting this technology with data from Dun and Bradstreet: so my recommendation is that Melissa Data purchase Dun and Bradstreet to combine their data breadth."

"There are some companies out there using Google or other sources to check / confirm if addresses are residential. If Melissa is not doing this, that could be an improvement."

"One of the problems that we ran into this year was we probably spent over 40 hours finding and trying to drill down to where specific bugs were in the program, which was a tremendous waste of time for us. There were a couple of updates to Windows this year, the program kept crashing. It happened on two different occasions over a period of a few months. Once we told them what the problem was - even though their tech support is great to work with - it literally took probably about two months to fix the issue where we could actually use the program the way we needed to use it."

"We have noticed that some of the emails and addresses return with confusing or incorrect codes, but for the most part, it is accurate."

More Melissa Data Quality cons

"Regarding Monte Carlo, I would say that currently we can have machine learning options. We might have to integrate MCP servers so that it can connect to multiple systems at once and we should have some kind of a placeholder for artificial intelligence integration."

"For anomaly detection, the product provides only the last three weeks of data, while some competitors can analyze a more extended data history."

"The biggest pain point with Monte Carlo is that we have created some rules, but those rules cannot judge everything, and I think the platform is a bit complex for someone new, so it can be more intuitive; a display adoption platform could guide the user on how to use this, like a DAP system."

"However, I still struggle a bit to find things in the current UI, so they can improve that aspect further."

"The automated monitors can also be noisy at first."

"Monte Carlo needs to stop their reliance on AI, as it is not going well and is degrading the entire product."

"Monte Carlo adopted AI just recently, so there is room for improvement in the accuracy of the AI."

"In some cases, with multiple tables, the UI sometimes crashes, but it is still the best I have seen so far, making it a great tool overall."

More Monte Carlo cons

Pricing and Cost Advice

"Pricing is very reasonable."

"You should have a good idea of the size of your data and the amount of cleansing you will be doing, so you will purchase the appropriate size bundle."

"I think it's worth the value for me to run it."

"This vendor has no equal in pricing for equivalent functionality."

"We are concerned that our own pricing is going up every year for Melissa Data products, but we highly recommend the services for people who are routinely sending out mailings."

"NCOA address verification was a requirement from USPS to send out the mailers. This was the only option that charged per address which was extremely helpful since we are a small non-profit school."

"Generally, the cost is ROI positive, depending on your shipping volume."

"The price for address validation is similar in all software. However, the price for geocoding decides the actual pricing. If you get their most accurate geocoding (called GeoPoints), then it will add about $10k+ per million requests."
