Dear Sirs,

I am user of MyDac 7.1.4 (my license to upgrade to new version has expired).
Now I'd like to use any solution to cope with SQLite. I can go two ways:

1. Buy LiteDAC
2. Buy UniDAC.

As I remember your DAC's were incompatible between versions, so:
1. If I buy LiteDAC will it work with my current version of MySQL DAC simultaneously?
2. If I buy UniDAC, will I have to uninstall my MyDAC and edit all may apps using MyDAC to render it to UniDAC?

Hello.

Different DAC products are compatible in case if their release date is the same. You will be able to define the compatible versions having learned the history of the products you are interested in:
LiteDAC - http://www.devart.com/litedac/revision_history.html
MyDAC - http://www.devart.com/mydac/revision_history.html
UniDAC - http://www.devart.com/unidac/revision_history.html

LiteDAC usage.
Unfortunately, there is no LiteDAC version compatible with your MyDAC version 7.1.4, since even the very first LiteDAC version was released after MyDAC 7.1.4. However, you can visit Registered Users' Area and find the latest MyDAC version available for you. If the latest available MyDAC version is 7.2.8 or higher, then there is a compatible LiteDAC version (in particular, MyDAC 7.2.8 is compatible with LiteDAC 1.0.1).

UniDAC usage.
Since UniDAC has a capability to access both MySQL and SQLite databases (as well as Microsoft SQL Server, InterBase, Firebird, PostgreSQL, DB2, Microsoft Access, etc.), you will get access to all the needed databases using only this one product. Moreover, UniDAC has a Migration Wizard utility (only for Delphi IDE), that allows conversion of MyDAC and other DAC projects to UniDAC (it is enough to have just UniDAC installed at that).

Thank you for your quick reply.
I found that UniDAC Pro Single has competitive price vs LiteDAC Pro Single (249$ vs 199$).

My question is, will UniDAC work along with MySQL DAC or it must be uninstalled first?
Does UniDAC provide the same features to for SQLite as LiteDAC does?

Hello.

UniDAC Professional Edition can work both with and without MyDAC. But to make UniDAC and MyDAC work together, their versions must be compatible with each other (the latest versions of our products are always compatible). Otherwise, to install UniDAC, you will have to uninstall MyDAC.

LiteDAC and SQLite provider in UniDAC are based on the same basic classes, however, since UniDAC is a unified product for work with different DBs, it doesn't include several server-specific features. There is a design-time component included in LiteDAC for simplification of creating user-defined functions. The TLiteLoader, TLiteDump, TLiteMetaData components allow to do more advanced settings for using entire SQLite functionality and specificity. Moreover, in the future, when adding features specific for SQLite only, they will be also added to LiteDAC.
