UNIX Composable

Management

A | B | C

The heart of Unix

composable

managementMeans that A didn’t do what you wanted to doWHY?A is a tight coupling ofGet Objects => Process Objects => Output as text“| B | C” uses prayer-based parsing to recreate the object so you can do one of the steps differently.NET allows us to do betterPipeline structured objects instead of textPipeline should be between get/process/Output

Successful but very inefficient

Slide4

Composable Data Model Progression

UNIX:

Standardized data encoding (ASCII files) allows the emergence of a set of domain-neutral utilities for composition and manipulation (e.g.

sed

,

awk, grep)SQL: Standardized data forms (Tables) allow the emergence of a set of domain-neutral utilities for composition and manipulation (e.g. join, query, groupby).NET Reflection:

Standardized object forms (

.net

objects) allow the emergence of a set of domain-neutral

utilities

for composition and manipulation

PowerShell Dynamic objects

.Net

Reflection model applied to XML, WMI, ADSI, ADO, etc

Extended types to ease composition, organize folklore, and facilitate discovery

Present: Windows PowerShell

New command-line shell and scripting language

As

interactive

and

composable

as BASH/KSH

As

programmatic

as Perl/Python/Ruby

As

production oriented

as AS400 CL/VMS DCL

Allows access to data stores as

easy

to access as

Expressions, Commands, and ScriptBlocks can run

In the foreground or background

On one or more machines

Over a LAN or a WAN

In restricted or unrestricted environmentsUsing short or long connectionsUsing impersonation or supplied credentialsInitiated by user input or by events

Slide28

Mobile Objects Model

Islands of optimization in a sea of interoperability

Whenever possible, use live .NET objects

Use typed property bags everywhere else

Live objects get serialized at runspace borders

Typed property bags using 22+ core datatypesEverything else is converted using ToString()Process can be tweaked with typeXML entriesAutomatically deserialized into typed property bags on receiptType:
