Universal Data Access Components Reviews & Product Details

Fast and stable native-level SQL driver. We use it for our medical software products to ensure reliability and speed. Review collected by and hosted on G2.com.

Nothing! Works well and as expected and stable. Review collected by and hosted on G2.com.

Ease of use, connection to a wide range of database platforms, a vibrant and active user community and excellent technical support. There are also regular update releases. I have used the product for more years than I care to think about, with virtually every release of Delphi there is, and it has never let me down. Review collected by and hosted on G2.com.

There is little to dislike as compared to all the other equivalent component sets out there, it is the best by a long way, in my opinion of course ;) Review collected by and hosted on G2.com.

First of all, I like that all supported databases work in a universal way.

Second, that for each type of database you can work with specific parameters.

Third, the freedom and full control by the developer of the requests sent to the database.

Fourth, the lack of configurations in strange places and external INI files.

Last but not least, a good set of assistants for fast request writing, monitoring and debugging of SQL. Review collected by and hosted on G2.com.

I would like a slightly more detailed help system with more examples of the most common problems when working with different databases with these components. Review collected by and hosted on G2.com.

I've written a Delphi program, accessing a spatial Posgresql database where all the tables are spatially joined and the look ups are spatial queries using PostGIS sd-functions. With parallel processing on a i7 PC (4 core, 8 threads), I achieved reading 214 000 records per second to process 19 Billion seismic records in 4 hrs and 36 minutes.

I may be forced to use FireDAC. I hope I will achieve the same look up speed. Review collected by and hosted on G2.com.

There are two things that I like the most with UniDAC. The first is the compatibility with the existing controls. Aside from some minor differences that are well documented, using these controls is just as easy as using the existing connectors.

I use the Professional Version of Delphi, which doesn't contain connectors to MS-SQL, as that is part of the Enterprise version which is vastly more expensive. The UniDAC components bring that functionality, without the obscene price. Review collected by and hosted on G2.com.

I can honestly say that there isn't anything I really dislike about this product. It does what it says, and does it quickly. Review collected by and hosted on G2.com.

The components are very easy to use, and it's simple to get data they way you need it. Once it's clear which elements to add, connecting to database servers is problem free. It's excellent that no external DLLs are needed when connecting to databases. Review collected by and hosted on G2.com.

The documentation could be improved, especially for not-so-experienced programmers. I often missed examples / snippets of how to operate different elements, answers that could be found in various forum posts (good that you have this available!), but snippets from forums should be merged into documentation at relevant places. That would be a great help. Creating documentation takes time, perhaps it would be an idea to create a "bounty" program where good user-created documentation videos could be integrated into the site, and the user (validated) could be offered discounts or "earn" licenses for products. It's probably cheaper to give out licenses than hire people to create documentation.

Point 2: it would be great to have a DEMO version of the full UDAC, including data providers. Even if these demo versions would only allow to get 5 records and work 30 days. Review collected by and hosted on G2.com.

Most useful Feature is the Migration Assistent Review collected by and hosted on G2.com.

Hard to say, because I didn't got any problems using UNIDAC with Delphi in my projects. Review collected by and hosted on G2.com.

The most important feature of UniDAC is the direct access to several DB without extra supporting files. It is true direct access rather than wrapping or going through .DLL file. It make the final product more efficient and project more economic. Review collected by and hosted on G2.com.

Needs more fine tune with error message catching. Review collected by and hosted on G2.com.

The number of database engine supported.

The simple way to use the VCL.

The fast result. Review collected by and hosted on G2.com.

Nothing ! It's the best DAC library I've bought ! Review collected by and hosted on G2.com.

Simplicity for connecting to different databases Review collected by and hosted on G2.com.

Sometimes, when I upgrade, the Oracle driver fails working with Oracle RAC, and the resolution takes longer Review collected by and hosted on G2.com.
