Universal Data Access Components Reviews

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.

I don't like that they didn't give me a job offer.

It is straightforward to use, reliable, and gives me access to every feature I need when writing database connected applications, large and small. It plays nice with the other 3rd party components we use such as DevExpress and Fast report etc, and it well documented.

Some of the dialogues can be a little clunky but the developer is very responsive.

Easier than I thought fits... best part works well with Rad Studio.

for a small company was expensive, considering yearly renewals

Compatibility with both Delphi and Lazarus/FreePascal.
Super-easy to use installer that seems to 'just work' year after year.
Abstraction layer to allow easier swapping between back-end database engines.

It is called Universal Data Access Components due to the large number of providers which is both a good thing and a bad thing. The negative for our company is that we only use a few providers regularly so the cost can feel burdensome, most notably when the CRM connectors and such were added a few years back. The positive is that without the bundling, we likely wouldn't have tested out such connectors...

Simple, easy to use and performant
A very good product for multi SGBDR access

More documentation about the impact of differents options with differents SGBDR.
For a non-specialist of a particular version of SGBR, it is quite difficult to choose the right option.

access to all DB in one product with native drivers
very quick access

i have small problems with direct mode to connect with oracle DB

Direct Access, Performance, Providers, Using

I didn't see anything wrong with the usage.

direct access to Oracle and Sqlite and some other databases

the only feature i miss at Universal Data Access Components is a provider for Paradox-Tables

Multi database access. I use it in MSSQLServer, MySQL, MariaDB and SQLite

Documentation from delphi have difficult access.
Examples from web are not always enough.

Multi database support and direct conenct without client.

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.

Using a common set of components to connect to several databases. Pooling it is also a feature I need.

Sometimes bug fixes takes much time.
New releases introduce bugs that takes time to solve

It's a solution that allows us to connect to many databases without needing to use drivers that may be missing from the end user computer.
Anyone who worked with Oracle knows how painful it can be to install their data access layer, Unidac allows us to never bother with this again.

It requires replacing existing components, but it's close enough to them that a simple DFM editing is often enough.

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 .

There is nothing I do not like. The Software does everything we need in our development environment.

Installation is simple; using the components is also easy. Documentation is good, and the ability to flip between database platforms by changing connectors is like magic. On the odd occasion I have needed support, the response has been helpful and timely. I have developed against SQL Server, MySQL, SQLite, Access, Oracle and Advantage database platforms with no issues at all. Another great feature is that there are no dlls that have to be distributed with an application.

There isn't really anything to dislike!

This product is easy to use, integrates well with my applications, simplifies code writing and speeds it up.

I found no negatives, since I installed it I have always used it

Ease of implementation and functionality of the components

There is no Excel-Component in unidac so I have to use TMS-Software for that purpose.

Use one connection for all databases and use always it

Improve a data dictionary and a Er Diagram (like entity dac)

Easy to use and to integrate with our software.

Actually it covers all we need and has continuous improvements.

I like the simplicity of confusing access to ODBC database. In particular I use it with the OS/400 ODBC on an iSeries Access system (previously AS/400) and it works fine and quickly.

I would like to use it with a specific product called Delphi/400 for accessing natively DB/400 database but is not supported by this tool

unidac is very performance data access library

it' easy to use and it have full option

Programs need not a driverinstallation ,
the componenten ussing is very easy
you have free choise of database like as slq,mysql,access
and variable change

I missing special fastreport components as 64-bit version,because this I can not change my Programs to 64-Bit, otherwise I am very satisfied

the simplicity of access from the mobile app

the too much time it takes to query large tables when I insert the order by clause

Great stability, no necessary to use external libraries. We don't even need to install a database driver to function. Our deployment made easy.

Everything works fine, we don't have any cons for now.

Fácil de utilizar, con soporte muy bueno.

Faltaría poder configurar un punto general para el formato de fecha.
