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 monitoring has reduced manual checks and flags data incidents with precise alerts

The most valuable aspect of Monte Carlo's observability feature is its automation of the monitoring processes, which eliminates the need for an individual to manually monitor numerous models or tables. It flags issues with precision and ensures proactive resolutions only on the affected components, thereby enhancing efficiency vastly. Monte Carlo's scalable nature further bolsters its value proposition. Once integrations are established, future model updates are automatically captured without additional setup costs or actions. Given that the data platform's needs perpetually grow, Monte Carlo provides seamless adaptability. The software manages data auditing and monitoring across platforms like Snowflake with its robust algorithms. By analyzing metadata over an extended period, Monte Carlo's flagging system, based on deviations from historical averages, ensures precise incident identification. Its ability to utilize custom monitors further extends its value, as users can implement logic-based rules and receive targeted alerts. The introduction of a performance tab greatly aids optimization, visually displaying runtime graphs to identify model issues quickly. Monte Carlo's near perfection in accuracy ensures every flag corresponds to a genuine issue, attested by its consistent performance over time. Monte Carlo's AI troubleshooting agent, which mimics human oversight through tiered analysis, provides ample support in incident resolution. This ensures incidents are well-documented, analyzed, and tackled despite limited access to all data layers.

Quotes from Members

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

Pros

"This serves our single need and we may utilize Melissa Data for other lookups, such as validate address lookup, in the future."

"Provides quality accurate data that our downstream solutions depend on."

"Ability to keep our data set clean and usable for our community searches."

"SSIS integration."

"We have only been using this for about two months, but it has sped up our processing significantly, making data mining easy and fast so we no longer have to spend an entire month gathering correct information on leads, as all we need is a list of home addresses and in minutes we have names and phone numbers to increase our chance of these leads becoming customers."

"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."

"Customer service was excellent, and their technical team provides top support for people wanting to use the technology."

"It has a straightforward, easy setup."

More Melissa Data Quality pros

"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."

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

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

"We found that Monte Carlo ended up being the best for us because it was able to do pretty much everything that the other competing tools were able to do for us, as well as being pretty entrenched already in our data architecture."

"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."

"It makes organizing work easier based on its relevance to specific projects and teams."

"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."

Cons

"Pricing is based on tiers, with each tier capped at a specified number of records processed. Once you go over the cap at one tier, you are automatically bumped to the next tier. However, they seem to count failed batch processes so it’s good to keep track of the number of records sent. They’ll fix the count when notified, but their system fails to detect actual successful processes versus failed processes."

"It will mix up family members at times, so we will change addresses at times that shouldn’t be changed."

"Address validation and parsing in a few countries have room for improvement."

"There are some hitches in setup, especially with the new encoding, but otherwise it’s relatively simple."

"Needs to provide more phone numbers, even cell numbers (scrubbed numbers)."

"The SSIS component setup seems a little klunky, but otherwise the product does what I expect."

"Overall there is a room for improvement in Customer Address Appends and Email Appends."

"Update feature"

More Melissa Data Quality cons

"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."

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

"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."

"Monte Carlo can be improved further by having much more AI integrated into it."

"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."

"While Monte Carlo frequently updates its UI platform, the changes might pose adaptation challenges for long-time users, as the continual evolution is not always intuitive."

More Monte Carlo cons

Pricing and Cost Advice

"Trial subscriptions (via cloud) are very cheap and easy to use. It’s a great way to test Listware to see if you want to go deeper with integration."

"Pricing is very reasonable."

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

"Pricing is very reasonable, no licensing required."

"Depends on situation. We prefer to have data onsite, but some might prefer web access."

"It is affordable."

"Fully understand your volume, both monthly and annually. Speak with a Melissa account manager, they will put together an effective solution to meet your needs."

"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."
