BDE still available as separate install. TQuery doesn’t seem to be there in
Berlin out of the box, but the usual old components TDataSetProvider
TDataSource TClientDataSet are.
How to install and add BDE components into IDE is described in

My most recent serious DB work was using standard IB components to open two
embedded Firebird databases and ADO to use MSSQL DB, and using TCLientDataSets
to merge data from all of them. There has always been a reasonable number
of good options of what component sets to use – even the old BDE works great,
the only real disadvantage is having to install and configure a separate
product. I expect that the FireDac is very capable – for instance I have read
(but not tried) that later versions allow one to do SQL joins on different
ClientDataSets which would have been most useful in my previous project.
BDE does not exist in Berlin. It is totally (and I mean totally) removed from
Berlin.
I have used Midas since 97 for all of my solutions (All are nTiered) since 97
and never regretted it.
However as Com seems to be frowned on, it is time for a change.
Having encountered a major issue with TSQL Connection at the outset, I am
somewhat discouraged. TSQL Connection does not support SQL Server after 2008
version. How can they justify selling a product in 2016 that does not support
SQL Server ?
Go figure.
As far as n tiered, I have had dealings with a current substantial Delphi
product that is 3 tiered but I am not sure if Datasnap is the technology used,
there is a good chance – I understand they have parallel code bases using
Delphi for Windows and Free Pascal for Mac, and can point at either Firebird or
MSSQL on Windows (Firebird on Mac). In other limited experience with Datasnap
it worked as expected.
Android and iOS, haven’t done more than toy projects yet myself, but so far
looks like it should scale.
Note about web browsers, on iOS and Mac TWebBrowser drives Safari, and on
Android it drives Chrome. Means that it has a fairly sparse set of events as
its a lowest common denominator, but it certainly works and is the native
browser – I knocked up a program for various OS’s with an Embedded web browser
in a few minutes, runs nicely on the Nexus and Windows.
I have seen what David did with driving the native Safari browser using the
code from the Windows VCL, bypassed Firemonkey altogether to get to the full
native Safari. Works very well, hardest part is getting to grips with Xcode
and Cocoa world of delegates and pointers to everything, but certainly Delphi
Berlin joined the Windows IDE and XCode together very thoroughly.

Subject: [DUG] BERLIN and DB connectivity
Some generic questions. I have just started using Berlin.
1. For DB connectivity, query etc. Which is better. Firedac, or TSQL
connection ?
2. TSQL connection does not support SQLServer 2008 R2, 2012, or 2014.
This is a pretty serious short coming. What do others think ? No doubt there
are many other shortcomings.
3. Can anyone experienced in the subject suggest a good n Tiered example
using Data Snap ?
4. Is Delphi a realistic platform for Android and iOS ? Friends that have
tried it, say it is just a demo toy, and a long way from ready.
Thanks very much,
Tony

Subject: [DUG] TChromium
Hi All
Does anyone have any experience with TChromium ... as in
delphichromiumembedded, DCEF3 ?
Installation in the VCL, distribution (files required), reliability, support etc
I am looking for a replacement for the standard TWebBrowser component in order
to view PDF files within a Delphi VCL application. TWebBrowser unfortunately
relies on the Windows Internet Explorer installation and current settings which
can lead to various problems.
Any info very much appreciated on this and the wider topic of extracting images
from PDF files generally.
Graham Marsden
