Universal Data Access Components

Unidac

Commentaires : Correct dans l'ensemble

Avantages :

Simple utilisateur connexion rapide aux bases de données Connexion à la base de donnée Mysql sans DLL le top

Inconvénients :

Une connexion un peu longue pour Firebird. Nous aurions aimé avoir la même chose pour Firebird sans DLL

Using for 10 years and has been the most reliable data tier since BDE.

Commentaires : 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.

Avantages :

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.

Inconvénients :

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

Comprehensive data access layer for Pascal languages

Commentaires : UniDAC has consistently allowed us to integrate with light and heavy-duty database engines (from SQLite to MongoDB with most of our usage in the PostgreSQL area). It has greatly reduced the effort to market for our products while also saving money by not needing to purchase Delphi Enterprise, Professional is enough thanks to UniDAC.

Avantages :

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.

Inconvénients :

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...

Easy and fast to use

Avantages :

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 ;-)

Inconvénients :

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.

Fantastic product

Avantages :

Many of our customers use a variety of database products. The applications we build are easily able to connect to every one of them to provide a seamless and fast unified experience.

Inconvénients :

I have used numerous other data access components in the past but did not have any undesirable experiences with the DevArt components.
