Integration improves accuracy and supports token-level embedding
The best features FAISS offers for my team include seamless integration with Colbert and the ability to use FAISS via the Ragatouille framework, which is tailor-made for using the Colbert model. Feature-wise, FAISS allows for more accurate result retrieval, and retrieval speed is also good when comparing the index size. Regarding features, I also emphasize that the usability of FAISS is very seamless, particularly its integration with Colbert and Ragatouille. FAISS has positively impacted my organization by helping us increase the accuracy of retrieval documents; when we store documents in token-level embedding, the accuracy will be high. Additionally, we do not need any external server to host FAISS, allowing us to integrate it with our backend framework, making it a very flexible framework.

An open-source database to hold customer data, but its performance should be improved
Firebird SQL significantly improved our data management in many parts of our self-developed ERP system. I rate the solution's performance and speed a six out of ten. Two or three database administrators are needed to maintain the solution. A few years ago, migrating data to or from Firebird SQL was a little bit difficult because the identifier names for tables or stored procedures were limited to 20 to 30 characters. Transferring the structure to Firebird SQL was difficult, but they fixed it in version 3, which was much easier. We are developing software with Delphi, and Delphi is also by Embarcadero. Using InterBase or Firebird SQL databases is very common, and you have some good tools for developing with Firebird SQL. Overall, I rate the solution a seven out of ten.

Quotes from Members

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

Pros

"The product has better performance and stability compared to one of its competitors."
"I used Faiss as a basic database."
"The most valuable feature of the solution is that it is reliable, offers good performance, and is easy to use."
"I like that we don't have to pay external fees to migrate this data. So, we are looking to relocate from Postgres or EDB."
"I appreciate the fact that, once the database is embedded, it doesn't need to be administered, and removes the requirement for a specific server."
"The reliability and ease of management are very valuable."
"The solution is very useful for stock management."
"Robustness is the absolutely main feature."
"I can deploy it on Linux, Mac OS, and Windows — it's very easy."
"The product was easy to use."
 

Cons

"One of the drawbacks of Faiss is that it works only in-memory. If it could provide separate persistent storage without relying on in-memory, it would reduce the overhead."
"It could be more accessible for handling larger data sets."
"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"We would like to improve the management of very large databases."
"The main feature I expect is to be able to work with different databases at the same time because that's a wishlist item for me."
"This solution isn't very user-friendly, or intuitive, which could be improved when it is developed."
"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"Technical support and performance could be better. We have some problems with this solution, but we don't know if the problem is with the database or the configuration. For example, sometimes, the users can't access the database."
"It would be nice to have a graphical user interface to handle the product."
"It would be interesting if they added functionality with redundancy, reputation, and variability."
 

Pricing and Cost Advice

"Faiss is an open-source solution."
"It is an open-source tool."
"We are using the free solution, so there is no cost involved."
"There is a yearly maintenance fee for the use of the solution."
"It's open-source and free."
"There is no licensing cost for this solution, as it is open-source."
"It is a public domain system as every customer can install it on their system without paying any license fee."
"Firebird SQL is an open-source solution, which means it is a free product."
"I was using the free version of Firebird SQL."
"The most valuable feature of the solution is that it is freely available."
