26 Agile Development Methodologies

Der Artikel [CW 05/2011] aus der Computerwoche listet 26 Agile Entwicklungsmethoden auf, welche ich weiter unten in einer Tabelle nach folgender Wertigkeit geordnet habe: Use, Licence, Tools, Support, Standard, Certification
Der originale Vergleich wurde durchgeführt von Pentasys [Pentasys 2010] und wird verkauft für €590.00 in Computerwoche [CW Marktstudien] durch die Firma Best Quality Institute [BGI].
In folgendem Bild zeigt der grüne Pfeil auf den Ort, wo sich anno 2007 die Agilen Entwicklungsmethodologien im Gartner Hype Cycle [Gartner 2007] befanden. Dasselbe Bild des aktuellen Hype Cycles aus dem Jahre 2010 ist nicht verfügbar, aber laut dem Index derselben Studie aus dem Jahre 2010 [Gartner 2010] sieht man, dass sich der Ort nicht verändert hat.

Die Methoden wurden verglichen anhand eines Spinnendiagrammes welche die folgenden neun Disziplinen des Software-Engineering berücksichtigt:

PM – Project-Management	T – Testing
QM – Quality-Management	INT – Integration
RM – Requirements-Management	W – Maintenance (Wartung)
SD – Systemdesign	B – Production (Betrieb)
IMP – Implementation

Es folgen die Methoden gewichtet nach:
Use, Licence, Tools, Support, Standard, Certification

FreeWare HV.CurrencyConverter © 2010 by H&V-Lima

Download HV.CurrencyConverter here Version 1.47

Why this application?
To get current currency exchange rates in a WinForms application serves as an example for a WebService frontend.
HV.CurrencyConverter lets you convert 131 currencies in some amazing 17’030 combinations.
But this is not the main goal of this application.

Being a WebService-Frontend there have been implemented several patterns:
- request to WebService www.webservicex.net/CurrencyConvertor.asmx is made in a background worker to not freeze the main (GUI-) thread
- since a WebService may be out of order or cannot serve all requests, a local XML-repository with the latest rates is maintained (in the user’s roaming profile)
- a second background task skims all active currencies in the dropdownlists once a day to have at least one almost current rate if no update cannot be made

 

Installation:
- only unzip the executable with its config file
- if your AntiVirus gets mad (because EasyDataEdit accesses a WebService on the Internet) and swallows its executable, please don’t be afraid and recover it from your AV’s quarantine area.

How to Linq ListBoxes with Except

There is a cool way to query ListBoxes with Linq.

Imagine there are three ListBoxes:
- A: with all currencies
- B: with selected currencies
- C: with available currencies, like A:.Except(B:)

The content of the visible ListBoxes is like:

For better comprehension I’ve created two sets (that do not materialize):
- Line 253: selectedCurrencies
- Line 255: allCurrencies

The resulting availableCurrencies are built in line 257…

…and materialized at the arrow

How to call a Stored Procedure through EF4?

In the following it is used the AdventureWorks DB on SQL Server 2008.

Add a new Stored Procedure from the DB to the Entity Framework via Update Model:

In the case I added the following usp:

EF has two parts, the DB-side (where we added the Stored Proc) and the object-side where we will create the needed classes now.
A double click on the new Stored Proc above (or right click, Add Function Import) opens the dialog Add Function Import below.

 

Click the first button (A:) to get the output column info from the SP, then the second button (B:) to create a new complex type, based on this info, then OK

This creates the complex type and C#-Function on the EF4-object-side:

Calling the SP through EF is accomplished like so:
Observe the datatype of the list p

Here comes the result of the first entry of p:

Compare this with the result of calling directly the SP in SSMS:

Example for Deferred Execution in Linq

Both examples use the AdventureWorks DB on SQL Server 2008 and the Entity Framework 4.0

1. Deferred Execution

In the first case the query is armed in line 23, but not materialized.

In line 27 result is “Bothell” (see watch on the right side)
Then there is done an update in line 32.
In line 35 the result is Berlin.

This shows clearly, that the execution of the query is deferred to the moment of enlisting.

2. NOT deferred Execution

In this case in the formulation of the query the result is materialized by calling the extension .ToList() in line 43.

Result in line 47 gives back “Bothell” as like Result2 in line 55, despite of having changed the address to Berlin in the meantime!
