Development Manager Computer Software Used the software for: 6-12 months ### "Great Connectivity....A Lifesaver!" April 28, 2026 5.0 I purchased UniDac for a personal project I am developing with TMS Web Core and XData. Migrating from FireDac to UniDac was problem free. But, I had a vexxing problem for work where we use Microsoft SQL Server. Unfortunately, Microsoft does not make a version compatible with Windows 11 ARM (let alone Management Studio) and made it difficult for me to perform Delphi dev even in a Parallels VM on my M4 Max MBP. I ended up having to install SQL Server in a Docker container. That could be accessed using FireDac. But, there was no easy way to perform backups or to switch databases. So, I wrote a utility using Delphi 12.3 and UniDac to perform database backups and restore. I am a user of dbForge for Postgres. At some point, I expect to purchase a license for MS SQL. Until then, I use BeeKeeper. But, in the end, UniDac has been a lifesaver for me. Pros Its ease of connecting to a variety of databases. I work with Microsoft SQL server by day and Postgres by night. Getting connected to the various instances is a piece of cake. Staying current with the updates - always easy to install. Cons Honestly, the cost for a subscription is a bit of hinderence for the individual developer. FireDac is free and comes with Delphi and the recurring cost for UniDac (like Delphi) can be a drag. Review Source DS David S. Consultant Computer Software Used the software for: 2+ years ### "I highly recommend Universal Data Access Components" August 4, 2025 5.0 Love it! I wish I would have started using it years earlier. Was very hesitant moving to a big boy database. Was used to dBase and the Absolute Database. Both worked but I needed to move to multi-million record tables. This does the job hands down. Pros Was able to get started and do basic functionality very quickly. With on-line searching I've been able to accomplish everything I've needed to do. Cons I wish there was more documentation. I see properties and procedures that I don't yet know what they do. I don't know if I even need them. Everything works as I think they should. Switched from [dBASE Plus](https://www.capterra.com/p/80138/dBASE-Plus/)[Absolute](https://www.capterra.com/p/115949/Absolute-Manage-MDM/) Needed a big boy database that could handle more users and bigger datasets Review Source Response from Devart October 15, 2025 Thank you for sharing your experience with us. Your feedback helps us to improve the product for everyone. TH Thomas H. CEO Food & Beverages Used the software for: 6-12 months ### "Easy and fast to use" July 27, 2022 5.0 Pros one of the few software solutions on the market that has done what it was designed to do without any problems and without errors right from the start. Microsft should take a look here ;-) Cons TPgDump component does not provide functionality to backup only some columns/datafields of a table (postgres) and then to only restore these values without restoring all the other existing and possible newer and essential content. Review Source Response from Devart July 10, 2023 Thank you so much for your feedback! We do really appreciate it. Marian S. Software Developer Computer Software Used the software for: 2+ years ### "The fast, the reliable and the universal database access components for Delphi/Lazarus" March 25, 2026 5.0 I have used UniDAC components in several applications and have gained experience accessing Firebird, Oracle, and Microsoft SQL Server databases. And what can I say: I’m a big fan of UniDAC. These days, one might well wonder whether you have to pay to establish a connection to a database system. In the Java environment, however, hardly anyone would do this or even need to. In the Delphi or Lazarus development environments, however, the situation is different. Yes, there are free solutions, but UniDAC still offers me added value, so — provided I’m not completely broke — I’ve decided to treat myself to a UniDAC license even as a hobbyist developer, rather than struggling with alternatives. And if, as a hobbyist developer, I already consider the advantages of UniDAC over other solutions is worth the money, then in a commercial software development context, I wouldn't even have to think twice about it. Pros UniDAC gives me the freedom to develop Delphi applications that can connect to a wide variety of databases—and for some DB systems, this can even be done without installing additional database drivers. UniDAC offers excellent compatibility (from legacy versions like Delphi 7 to the latest release) and performance. Whenever a new major version of Delphi is released, a corresponding updated version of UniDAC is released shortly thereafter. The most compelling advantages for me compared to other solutions were the ease of setup, the broad support for IDEs and databases, the ability to access the database systems I use directly (without additional drivers)—and the speed of database access. Cons I can’t really think of a direct downside. Of course, there’s the price... For someone who distributes software for free—whether out of enjoyment, for personal use, or simply to share their creations—the price is certainly a hurdle. Especially since there are free alternatives like ZeosLib. Review Source RS Rainer S. CEO Information Technology and Services Used the software for: 2+ years ### "Unbeatably good components" March 26, 2025 5.0 The components are easy to deploy, allowing our software to be used with Firebird, Oracle, or MS-SQL without any programming changes. The components have functioned reliably even across multiple versions. Pros I've been using the components for many years. They're very stable and performant. New Delphi versions are also supported immediately. Customer service responds quickly and competently to any questions. Cons I didn't notice anything that wasn't good. Alternatives considered [Firebird](https://www.capterra.com/p/165772/Firebird/) Reason for choosing Universal Data Access Components The components work with the simple Delphi version and save a lot of money with each release. Review Source Response from Devart April 15, 2025 Thank you so much for your feedback! We do really appreciate it. MD Marek D. developer Medical Practice Used the software for: 1-2 years ### "UniDAC is feasible upgrade option from older DB components" October 23, 2025 5.0 We use UniDAC for large business app with MsSQL and Firebird databases. UniDAC is highly advanced database component set for Delphi. Pros UniDAC provides native driver for MsSQL - no need for Microsoft OLE DB drivers, wide variety of useful properties and events and good recovery after connection breakdown and reconnect. Cons Fetch records management is hard to use with MsSQL. Opening query with unfetched records leads to "New transaction is not allowed because there are other threads running in the session" when another transaction tries to access same records. We programmed own requery management when user needs more records than initial load (similar to MaxRecords in ADO and client side cursor). Review Source Response from Devart December 17, 2025 Thanks a lot. Your feedback is valuable to us. SZ Solon Z. Software developer Accounting Used the software for: 1-2 years ### "Reliable Database Connection with UniDAC and Delphi" September 24, 2025 5.0 We use UniDAC in our company’s EMDI business management software. It has been reliable, fast, and makes it simple to connect with both Firebird and MySQL. I also really like the included dbMonitor tool, which makes it much easier to debug and trace database activity during development. Pros Works great with Firebird, which is our main database, and also with MySQL for our web apps. Easy to use and very stable. Cons Error handling could be improved. In some cases the feedback is not detailed enough, which makes debugging harder and less efficient. Review Source Response from Devart October 15, 2025 Thank you for your feedback. We are always looking for ways to improve. AH Attila H. Developer Computer Software Used the software for: 1-2 years ### "A useful component package" September 24, 2025 5.0 We are a small company and we mainly work with Firebird and MSSQL databases. We recently started using PostgreSQL and the conversion was surprisingly easy with UniDac. Pros \- easy install and use - excellent performance (Firebird, MSSQL) - easy to learn, simple development Cons \- nothing - Updates arrive relatively often, and we always wonder if they are necessary. We usually wait for less busy days and install them then, so far we have not had any compatibility issues. Review Source Response from Devart October 15, 2025 Thank you for your feedback. We really appreciate it! CB Chris B. Technical Director and Lead Developer Restaurants Used the software for: 1-2 years ### "Best Database Compoonents for Delphi" June 24, 2025 5.0 We've been using it for more than 10 years. Awesome product, and will probably keep on using it for the foreseeable future. Pros Ease of use and the myriad of databases to connect to instantly. Easy to install and almost no learning curve coming from a Delphi background using their components. Cons Nothing. Everything is just fantastic! Like I said, if you are a Delphi programmer coming from the Borland BDE days and working with the standard database components, you'll find these extremely easy to integrate with. Review Source Response from Devart October 15, 2025 We are so grateful for your review. Tim S. President Computer Software Used the software for: 2+ years ### "Using for 10 years and has been the most reliable data tier since BDE." May 11, 2022 5.0 We have been able to contact support and gotten a night build change to access Oracle when they changed to allow an off site redundant server configuration. Pros The software has built in code to access database servers directly. For example, you can write a single EXE that can access an Oracle database WITHOUT Oracle intalled. They have the code for OCI built in. Yes, you can use OCI and OLE DB and ODBC and hit 20 other databases with the same code. Of course you can access MsSql the same way. What does this give you?? You can make an Android app that connects direct to a Mssql database over the internet. Maybe you will do REST services later, but quickly make an awesome app. Cons I don't like that they didn't give me a job offer. Reason for choosing Universal Data Access Components Flexibility Review Source Response from Devart January 19, 2023 Thank you so much for your feedback! We do really appreciate it. RL RONALDO L. Eterno estudante Computer Software Used the software for: 1-2 years ### "O Universal Data Access Components é o melhor" June 25, 2025 5.0 Desenvolvo pequenos aplicativos em todos eu uso o unidac por gostar mesmo e pela simplicidade. O Universal Data Access Components são componentes sempre irei usar. Pros O que eu gosta é praticidade de não ficar preocupado em ficar colocando dll na pasta do exe, muito bom, eu recomendo. Cons Na minha opinião ainda não encontrei nada que não goste mais quando eu encontrar eu falo no suporte o que eles poderiam melhor.

Manager Information Technology and Services Used the software for: 2+ years ### "Very useful for various DB Architectures" April 27, 2022 5.0 We were able to easily migrate from our old Data Access software to UniDAC. Pros We especially like the ease of adapting our software to using the different database environments (Interbase/Firebird, Microsoft SQL, etc) that are used by our clients. Also the opportunity to purchase the source code is very helpful . Cons There is nothing I do not like. The Software does everything we need in our development environment. Review Source Response from Devart January 19, 2023 We are so grateful for your review. PT Peter T. Developer Education Management Used the software for: 2+ years ### "Easy access to all important datasources from Delphi-programs" May 14, 2022 5.0 Very good performance of the components, support for the current releases of the database software Pros direct access to Oracle and Sqlite and some other databases Cons the only feature i miss at Universal Data Access Components is a provider for Paradox-Tables Review Source Response from Devart January 19, 2023 Thanks a lot. Your feedback is valuable to us. ML Martin L. Manager ICT Judiciary Used the software for: 2+ years ### "Universal Data Access" October 5, 2023 5.0 Pros Pretty easy application development, reliability, excellent functionality. Cons I can't think of anything at the moment. Review Source Response from Devart January 11, 2024 Thank you so much for your feedback! AG Artur G. Application developer Broadcast Media Used the software for: 2+ years ### "I do not understand, what is this field for." October 5, 2023 5.0 I't hard for me to admit, that I still do not understand native methods for SQL databases connectivity in Delphi. I'm useing DAC components from very beginning. Pros Very easy to install, easy to use, reliable. Cons Problem with datetime2 field type in MSSQL, it should have automatic conversion to TDateTime. Problem with setting NULL values in INSERT or UPDATE query with params. Review Source Response from Devart January 11, 2024 We are so grateful for your review. aP alexandre P. Dev Computer Software Used the software for: 2+ years ### "Unidac Review" October 6, 2023 5.0 Pros Direct Acess to databases. Not needing drivers and concentrating all connection demands on the executable is what makes UNIDAC different for me. As far as I've seen, the native options for Delphi and C++ need drivers or libraries to work correctly Cons UNIDAC fully supports me and I would only consider a progressive, more aggressive discount percentage during renewal. Review Source Response from Devart January 11, 2024 Thank you for your feedback. We really appreciate it! NG Nihat G. develop Computer Software Used the software for: 1-2 years ### "Universal Data Access" July 27, 2022 5.0 Pros It's nice that it allows direct connection to the database. I found that they work faster in databases that connect, I don't know how much it can sell directly to the connection. Cons I had Interbase database connection problems on iOS version Review Source Response from Devart January 19, 2023 Thank you for your feedback. We are always looking for ways to improve. PB Peter B. DBA Computer Software Used the software for: 2+ years ### "Database access everywhere" July 28, 2022 5.0 I've been using it for years and it lnever let me down. Pros I need access to different types of databases from the same program. The transparency lets me do this without having to write a program for each database type. I love it. Cons No Cons for me. Everything I need is available, and the setup is easy Review Source Response from Devart January 19, 2023 We are so grateful for your review. MH Marko H. Developer Architecture & Planning Used the software for: Less than 6 months ### "Great product" May 10, 2022 4.0 Mostly positive. Have some reare random Access violation issues. Pros Multi database support and direct conenct without client. Cons Some bugs I reported to support. For example: - Some versions of MS Sql Server had some serious bugs (fixed already) - Locate for TDateTime doesn work correctly - Some Access violations on random occasions.

Softwareentwickler Computer Software Used the software for: 2+ years ### "Zeitersparnis und Stabilität top!" March 27, 2026 5.0 Pros Besonders beeindruckend ist die enorme Zeitersparnis durch die konsistente API: Einmal geschriebener Code funktioniert ohne große Anpassungen für unterschiedlichste Datenbanksysteme. Die Stabilität der Komponenten ist auch bei hohen Datenlasten hervorragend, und die Integration in die IDE (Delphi/C++Builder) fühlt sich sehr nativ und flüssig an. Man merkt einfach, dass hier jahrelange Erfahrung in der Datenbankentwicklung steckt, was das Vertrauen in die eigenen Anwendungen stärkt. Cons Gelegentlich wirken die Fehlermeldungen etwas generisch, was die Ursachenforschung bei Verbindungsproblemen manchmal zeitintensiver macht als nötig. Zudem wäre es wünschenswert, wenn neue Features oder Provider-Updates noch schneller in die Basis-Dokumentation einfließen würden. Review Source YR Yeoh R. Programmer Computer Software Used the software for: 2+ years ### "Great set of data access components" June 26, 2025 5.0 We have been using this library for almost 20 years now, and found it reliable, easy-to-use, and frequently updated to support new database versions. Pros Wide range of databases supported. Supports database-specific features. Good variety of components to support many use cases. Easy to use. Fantastic support. Cons Have not encountered any major issues in our almost 20 years using this set of data access components. Review Source Response from Devart October 15, 2025 Thanks a lot.

Director Computer Software Used the software for: 2+ years ### "Best for connecting to databases" March 26, 2025 5.0 I have been using Unidac for Delphi for over two decades to connect to Oracle, MySQL, NexusDB, SQL Server, PostgreSQL and Firebird databases. The product is stable, accesses databases with excellent performance and Devart's technical support is very good. Pros Excellent performance. Connection to multiple databases. Use of "macros" in SQL commands. Cons Since it has a lot of options/settings, it took me a while to get to know and use all of its features. Review Source Response from Devart April 15, 2025 We are so grateful for your review. JB Johan B. Owner Education Management Used the software for: 2+ years ### "Fast and reliable components" March 26, 2025 5.0 The product is reliable and fast - I have not suffered any loss of data while accessing my data is fast.
