Design Factors 11: For CRUD operation in BLL, when we use the business entity and when do use parameters?

Business entities can be passed as method parameter in BLL, or all data elements can be passed separately in BLL methods as method parameter. Some design also may support the Business Entity class to include the corresponding CRUD methods, which basically doesn’t require any data element to be passed in the CRUD methods.

Design Factors 10: What are the mapping criteria for BLL classes and CRUD methods?

BLL classes can be defined with respect to physical or logical business entities, DAL classes, as vice versa. This mapping process can include one to one, one to many or many to many technique. For example, we have two business entities (physical or logical), named “Order Summery” and “Order Items” for an e-commerce application. Having a one-to-many mapping relation with BLL and DAL in class level can contain one separate BLL class, as “OrderBLL”, and two separate two separate DAL classes, as “OrderSummeryDAL”...

Design Factors 8: How the layers communicate with next level layers?

For a three layered application model, in some cases, the UI interface layer can use the DAL directly, rather using it via the BLL (i.e. “immediate next layer”). This type of application model generally includes a small set of classes and methods in business logic layer, ignoring the mapping all functionalities from DAL to BLL. This design issue provides a sort of performance, by reducing the engagement of intermediate layer(s). On the other hand, we can have a model, where a complete set of functionalities...

To improve the application performance, “Caching” is one of the popular techniques in current trend of best practices.

Sometimes, putting the cache mechanism in a separate layer provides better isolation and control over application space. If so the cache isolation, expiration and coupling with other layers policy should be addressed properly. Technorati Tags: architecture,.net,layered...

There are few entities which data are not been changed very frequently, but one or two items are added over few months. For instance, user type, product category, order type, payment mode. For better database operations values of these fields are kept in database and been referred to other entities as foreign keys. But interestingly values of these “Type” entities are used very frequently in coding layer, where developers had to use the hard-coded primary key value or the string value of this type...

Design Factors 3: Where and how the joined operation (fetched from multiple data tables) is placed in business entities?

When we need to retrieve result sets from multiple database tables via join operation a common practice is to use Generic DataSet to store the result. We can consider Custom Business Entity for the cases where the joining operation can be determined at the software design time, which provides faster execution time than DataSet. Also in some cases joining operation is required to be implemented in application end, rather database end query, especially when multiple entities are required to be combined...

Design Factors 2: To which context Business Entity classes are mapped?

For simple applications, mapping directly from physical table to logical business entities reduces lots of cost in programming, especially while using code generators. However, no matter in sample or complex applications, besides mapping physical tables, there are few areas which might not be suitable to be mapped directly from databases tables. To map one-to-many relation from database to logical application model, some design creates a base container class for the business entities, which includes...

Custom Entities are generally simple and faster than DataSet, where as it includes more involvement from developer end, as opposed to DataSet, which includes lots of built-in functionality, along with several trade-off in performance end. Choosing the right business entity is one of the basic parts in the software architecture, which fits accordingly in application requirements and development...

LINQ – We can use intellisense on queries !!!

As a developer always we want to have the opportunity to write the codes properly, along with programming language specific words and keyword to be highlighted in to different colors. Also VS.NET developers enjoys an IDE features named “Intellisense”, where while wring codes, a list of probable class or object name appears in a list and can be inserted to the code segment, just by selecting the appropriate item from the list.
