Week 5 - Powerful Database Access with FireDAC and InterBase.
All Skill Sprint Replays
FireDAC Tips, Tricks and News
The session shows how to solve traditional data access issues with existing and new FireDAC features such as new BLOB streaming, Batch Move, updated LocalSQL and more. The session is oriented toward business data application programmers who need high performance, low memory usage and stability of their applications.
If you need to manage distributed data over multiple locations then don't miss the product address for InterBase! The next generation of InterBase is coming soon and will be super charged with a powerful new change tracking engine that makes managing distributed datasets a whole load easier!
No App is An Island - Universal Enterprise Data Connectivity for the Multi-Device World
No App is An Island: Universal Enterprise Data Connectivity for the Multi-Device World
featuring Cary Jensen
FireDAC is the ultimate multi-device data access library. Enterprise data access can be challenging. While products like dbExpress have solved many of these problems, what is needed is a data access engine that can deal with the rapidly changing world of IT. Multiple devices, OSes, and form factors create a plethora of touch points. FireDACs high performance, unified API and native driver support are the answer.
In this webinar replay, you will learn how software developers can use FireDAC simple application. Then we'll take things up to the next level by moving our simple app to multiple device form factors, and scale it from a single back end to multiple clients.
FireDAC Architecture and Overview
Migrating BDE Applications to FireDAC
Performance of the Array DML Command (FireDAC)
Tutorial: Using a REST DataSnap Server with an Application and FireDAC
Local SQL (FireDAC)
If my Windows application uses IBLite for a local database, does the application 'phone home' to an Embarcadero server to authenticate the license when it is run by the end user?
User app that uses IBlite will call home one time when the app first starts up to validate the license. It will not recall home again.
Are there any differences between the XE5 & XE7 version of FireDAC? I'm asking because Pawel is using Delphi XE5 for the presentation.
Check out the "what's new in FireDAC XE7: embt.co/firedac-whats-new
How does FireDAC relate to the use of ClientDataSet? Are they completely different approaches?
FDmemTable is the FireDAC equivalent
Which of the many settings would you use to optimise e.g. a batch of 50,000 append operations to the same table with a TFDQuery
You can use Cached Updates and then apply updates. also check out Batch operations in the FireDAC Docwiki
I have a datasnap app where i have an express connection and access to procs are created on the fly. Is firedac suited to this kind of app
Can you use the bluetooth connection to access a local IB database on host PC
Yes - you'll need the mobile addon pack or enterprise and above and use datasnap or EMS or some other remote procedure call mechanism - REST, SOAP, etc.
Is there a runtime only version of the FireDAC monitor that can be used at a customer site for troubleshooting?
How easy is it to connect FireDAC components to a Sybase Advantage Database server? Is that what the TFDPhysADSDriverLink is for?
Connecting to Sybase would be very similar to connecting to InterBase. Yes, you would use TFDPhysADSDriver.
Is there a Wiki on deploying a FireDac Delphi Application to a client ? Listing of modules that have to be part of the set up?
http://docwiki.embarcadero.com/RADStudio/XE7/en/Deploying_on_Windows_(FireDAC) should get you started on Windows.
Any examples on how to use stored procedures in a database from FireDAC?
Do you need to use a FDGUIxWaitCursor when creating a Service or ISAPI DLL? Would it be bad to add it anyway?
FDGUIxWaitCursor is required for all FireDAC applications. But when your application is GUI-less, then you should set FDGUIxWaitCursor.Proivider to 'Console'. Then you will have a "dummy" wait cursor.
In DBExpress and Oracle 11g, all Integers are represented as ftBCDfield. Is FireDAC reoresenting integers there as integers or BCD ?
FireDAC represents Oracle native integers as integers.
We converted our server side datasnap services to use Firedac and replace dbExpress, in the future will there be a client side Firedac component to replace TClientDataset that allows the applyupdates type of update?
Right now all FireDAC datasets support cached updates:
