• Deepu.MI Message vs Service.

  EmailValidation message vs EmailValidation Service. SOA is mostly about services and messages. Rather than create a number of services with different names would it be recomended if we create 1 generic service and have it request/reply messages. For ex: EmailValidation service. Instead of creating a service for email validation, create a validationService and have it process all the validation messages for the application. Just wondering how ...Show All

• Jim Mace Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project. Then maybe I will write mapper classes for bussiness classes to map DB tables or using an O/RM tool or an ODBMS . Think that this project is big one and it has long deadline. You will develop it 2 or 3 years. Requirements will be changed. To develop this project with OOP designs and n-Tier application design is good idea. But I am asking myself ...Show All

• rbedick db design question. . .

  My boss and I are having a disagreement. In our schema (SQL 2000), we have SSN nullable indexed.

The driver on this was an employee number. If the employee number is found, data is updated, if not it is inserted. Everything worked fine when it was one branch office. ...Show All

• LAPIS Online/Offline mode, abstracted

  We are planning an enterprise app. The basic setup will consist of a winforms client that will connect via remoting to a centralized app-server over a vpn. We must be able to provide basic functionality even in the event of a network outage. The plan is to have a local database that is a stripped down version of the main database. The local database will get updated periodically so it stays roughly in synch with the main database. The client wil ...Show All

Underlying reader class use type data set and extend reader class for type dataset f ...Show All

• nasturtium86 Serviced component architecture issues (State management/ OOD).

  I've seen serviced components abused and misused due to inherent limitations in how COM operates and now I’m looking to architect a web based, OO, n-tier system and wish to avoid the same mistakes. In my system there are two architectural problems: Much of the data is common across users, complex and potentially quite large, which leads to a large number of objects when using standard OOD (not so good for COM as I understand ...Show All

• sunil2006 help on writing messaging adapters

  Hello, Guidance requested on writing messaging adapters! My system uses a messaging backbone transporting Xml files not SOAP web services. The message system is Biztalk but that should be irrelevant. I would like guidance on how to design and implement the adapters that take binary data from the business layers and communicate with the backbone. To produce a good adapter, I think I should implement several messaging design patterns. ...Show All
