Good (Free) Database Choice For Simple Local Database For Delphi 2009
For years I have used the BDE and dVolga ( no longer abailable ) but want to learn how to use other third-party and/or Delphi 2009 vcl components for simple databases. For a simple local database with only one table and 6-8 string fields with graphic field support for one field what is a good choice? What is available to do this without buying anything or possibly with a freeware component? Should I use DBExpress? Is a commercial database application necessary to create the database? Is something available from Microsoft as a free download to create and possibly edit an Access database? I have looked at various BDE Alternatives but allmost all of them cost $350 to $750 which is more than I want to spend for some simple applications. I have had some sucess with TDataSource and TClientDataSet with xml but I am afraid that the database will get too large storing the images. Can I create a simple database with a path to an image file stored in a field and load the image into TDBImage or ImageEN baised on the path stored in the database foe the selected record? Thanks

Well, you could create your own database! Your example is really simple to implement and I did so more than once in the Atari/Apple era in the mid-1980s. But, back then it was not so simple as one had to write basic I/O fetch/get/put routines using the BIOS api. Reduce your problem down to pseudo routines/code to access a "DB" of fixed length records that are read/written from a structured record format of strings. Use a string key -- dBase did. Presuming that this is a desktop app and single user, your task here is easier than searching the universe for a free, multi-user, SQL db to match your requirements that you can interface to whatever. -- Steven S.

Try Turbo Power Flash Filler
http://sourceforge.net/projects/tpflashfiler/
> Should I use DBExpress?
If there is a driver for your selected database and you want to support
more than one data servers then yes.
> Is something available from Microsoft as a free download to create

You already have them installed in your delphi they are the DBGO (ADO)
components

Yes. How the images are handled outside of the database is your own
responsibility though (aka you have to write some code).

Yes. you could. But you have to aware that TClientDataSet is in-memory dataset. Whatever changes you do on the rows in TClientDataSet aren't persist to your permanent storage. You have to call SaveToFile/SavetoStream to save your data explicitly. TClientDataSet perform generally fine for 2-3K rows of data but it will get slower if the rows increase. -- Best regards, Chau Chee Yang E Stream Software Sdn Bhd URL: www.sql.com.my SQL Financial Accounting

Absolute DB from www.componentace.com is a good and easy to use one.
It has a free version for any personal use.
