Re: Disappointed in mr Hariri2006-11-10 03:55:39 AM delphi229 Don't know much about LINQ, AFAIK, it is a way mimic SQL commands from the .NET framework, correct me if I am wrong. ECO is a full set of MDA development tools, integrated to BDS. I don't think they compete. OTOH, I can think about ECO apps using LINQ when appropriate, say, when dealing with non-structured data.

QuoteDon't know much about LINQ, AFAIK, it is a way mimic SQL commands from the What they show off the most is the language integration (LINQ). But on the back end, when using LINQ against a database (DLINQ), you create a new set of "DlinqObjects" (maybe similar to the ECO Space in ECO? not real sure here), which gives you a design surface. From there, you drag and drop tables from the Server Explorer on to your design surface to create your model. The model defines the types, column binding, relationships, etc. From this model, VS generates a code file that defines your tables, columns, relationships, etc. From there, obviously LINQ also includes language enhancements for C# and VB.NET, allowing you to query the data in a straight forward way: int skipRows = (PageNumber - 1) * PageSize; var users = ( from u in db.Users where !u.Deleted orderby u.Username select u ) .Skip(skipRows) .Take(PageSize); I really don't know how much overlap there is between ECO and LINQ (or other frameworks like XPO). I have never used any MDA tools or modeling until playing with LINQ. LINQ itself is very handy for querying anything, including your own lists and XML. DLINQ seems like a thinner O/R mapping than what I have seen in other products, with the direct integration of querying into the language. |

Although I think the underlying tone (not by Chad but by Tim) was that Win32
is dead and everyone should move to .Net, and thereby Delphi should not be considered 'at all'. "Chad Z. Hower" <XXXX@XXXXX.COM>writes Quote"Henrick Hellström [StreamSec]" writes: |

Re: Disappointed in mr Hariri
I personally think it is overhyped, but that is just my opinion. I am not
saying it isn't a nice piece of technology/innovation, but ECO sounds like the basket that they are putting all their eggs in, if you listen to some of the people talk about it around here. If ECO was that great, I am sure Borland would have alot more people using their development tools. TheServerSide did ran an article about O/R Mappers and ECO was listed, but it was never mentioned by anyone in any of the (probably) 300+++ comments. Most people seemed to like NHibernate good enough, or other [cheaper] tools like IdeaBlade DevForce. I believe they have a "free", more limited version available for download, but I am not sure since I don't do that kind of development and I believe it only integrates with Visual Studio. I laugh hysterically everytime someone brings up ECO and talks about it like it is the next best thing since sliced break. Especially, considering it isn't even useful across many domains of software development (useless if you do no database development, etc.). How much would an ECO plug-in for Visual Studio run (theoretically), if Borland were to detatch it for third-party licensing. Would it even have support for .NET 2.0++ goodies in it? Considering Delphi.NET is not gaining a huge following (third version of this personality, IIRC 8, 2005 and now 2006) and many D32 developers are migrating to C# for .NET development (and many to Visual Studio as the need for 2.0 features become more pressing as time goes on; and now 3.0 soon), they better have something that caters to a wider variety of developers than ECO. One can only hope. - Nate. "Craig" <XXXX@XXXXX.COM>writes Quote>Don't know much about LINQ, AFAIK, it is a way mimic SQL commands from the |
