I consider it required reading for anyone considering starting a business.



Just want to share this message from his book. (The following are copy from his book.)



The Fatal Assumption is : if you understand the technical part of the business, you understand a business that does technical work.



And the reason it's fatal is that it just isn't true.

In fact, it's the root cause of most small business failures!

The technical work of a business and… Continue

If you need to reduce the number of calls,use DTO. DTO can hold all the data for that… Continue

Reflection allows the developer to dynamically create object and calling its methods.





Let's look at the following two ways to achieve the same result.



//Normal way to call an object



BusinessObject bo=new BusinessObject();

bo.ExecuteValidation();





//Reflection way to call an object



object retval = null;

Assembly assm = Assembly.Load("MyApp");

Type objType =… Continue

{

xml= XYZ.Util.Serialization.SerializationUtility.ToXMLStringWithTags(retVal).Trim();

}

Eachday, the technicians go to the head office and pick up service orders that are printed on paper forms.

The technicians spend some time discussing who goes where and who does what.

Urgent service orders are manually prioritized.

When all is done at the head office, the field workers drive away to the field.



If an urgent call comes in during th day, the head office staff has to call out to the field workers and hope one can come back to pick up the paper-based… Continue

Field Service is about fixing things in a planned maintenance schedule or because of a breakdown situation.

The effort involved have to be carefully noted, in terms of steps taken, the time and effort required, as well as parts used.



At the end of the process, an invoice is usually created and the customer receiveds the invoice.



service Need -> Detail Effort -> Plan effort -> Fix -> Report effort -> Create Invoice -> Invoice

Windows Mobile application in Supply Chain Management

An expired asset is something whose value diminishes over time.

Example includes a warehouse full of bananas and a ticket to a ball game.



Your knowledge and asset are your most important professional asset. Unfortunately, they're expiring assets.



Your knowledge become out of date as new technique, language and environment are developed. Changing market forces may render your experience obsolete or irrelevant.



As the value of your knowledge declines, so does… Continue

One broken window, left unrepaired for any substantial length of time, instills in the inhabitants of the building a sense of the abandonment- a sense that the powers that be don't care about the building. So another window gets broken. People start littering. Graffiti appears. Serious structural damage begins. In a relatively short space of time, the building becomes damaged beyound the owner's desire to fix it, and the sense of abandonment becomes reality.

There will be 4 layers for enterprise business application in .net.

- The Presentation Layer (UI)

- The Business Layer (BLL)

- The Data Access Layer (DAL)

- The Data Layer (Data Store)

Layer are supposed to talk in this way.

UI -> BLL -> DAL -> Data Store

we use DTO (Data Transfer Object) to pass the object to other layers.

DTO is just a class with property. so we can set and get the properties.

UI = aspx + aspx.cs (or)…
