-<title>Introduction to Data and Data-Driven Applications</title>
<para>
-Summary: In this chapter we introduce key concepts at a high level. There is
little code, but a fair amount of diagramware to illustrate databinding and
replication.
-</para>
-<para>
- Databinding marries the content of an XML datastructure with the
OpenLaszlo objects (such as nodes, or views).
-
- Allows separation of content from presentation
- Datapaths are objects that connect views to data.
- Attribute values update automatically when the data changes.
-</para>
-<para>
-We give a conceptual overview of the logical differences between the DOM-based
and datapointer/datapath-based ways of manipulating data, with a preview of how
these approaches will be reconciled in later chapters.
-</para>
-<para>
-Datareplication is introduced, and the difference between implicit and
explicit replication.
-</para>
-<para>
-We then explain some useful design patterns involving datasets, both locally
on the client, and between client and server.
-</para>
-<para>
-Finally, we introduce the abstract concept of the dataprovider.

-------Notation
-------Supported subset in LZX
-Databinding -- conceptual overview
--- Datasets - in-memory representation of XML data
------ The LzDataNode type
------ The LzDataElement type
------ The LzDataText type
--- Updating views by data (data determines behaviour of LZX object)
--- Updating data by object (object updates dataset)
-Databinding APIs
--- Datapointer (tag) APIs
--- DOM (prodedural) APIs
-Replication
--- Explicit Replication with <replicator> tag
----Implicit replication without <replicator> tag
-Client-Server Data patterns
---- REST and HTTP
------ Query types
------ Request and response headers
------ Query Paremeters
---- Ajax and the HttpRequest() object
------ This is "syntactic sugar"; same functionality as with datasets
---- Master-Detail
--- Reconciling Server and Client data models (updating databases on server)
-The dataprovider object
-</para>
-<para>
- Any subclass of LzNode can be data-bound.
- All data-bound objects have a datapath.
- The XPath may be absolute or relative.
- <view datapath="ds:/path/to/data/text()" />
- Individual attributes of nodes can be data-bound.
- Attributes must be settable.
- The object must have a datapath.
- You must use relative XPaths for the attribute bindings.
- Multiple attributes of the same object can be databound to
different locations.
- <view datapath="ds:/path/to/data"
- x="$path{'@xposition'}" />
- Datapaths cascade through the view hierarchy
-<view datapath="ds:/path/to/data">
- <view name="unboundView">
- <text datapath="text()" />

The term <indexterm

refers to numbers, characters, or text

a Laszlo application. The specific form that data takes in a Laszlo
application
