There is a possibility for integration with nearly any external applications
and hardware, basing on commonly recognized open standards and data transfer
protocols.
There is a whole set of means in 1C:Enterprise:
to create, handle and exchange data of various formats;
to access all objects of 1C:Enterprise system realizing its
functionality;
to support various data exchange protocols;
to support interaction standards with other subsystems;
and to create original Internet solutions.
Text Documents
The script language
of 1C:Enterprise allows to create, dynamically build and write text documents.
Establishing data exchange with text documents (files) may be as one of the
least resource-intensive ways to arrange interaction with other information
systems.
In addition to usual ways of working with text documents (such as
reading/writing, add strings, get strings), developers have the possibility of
dynamic building of text documents, basing on templates created in advance.
A text template's capabilities:
Creation of the template's named areas, specifying the area's language;
Text template's fields' layout description;
Field's data output format description;
Field alignment description;
Description for automatic word-wrapping for a field's value representation
at report formatting;
Use of blanking when text cannot fit its field;
Getting a text template as similar as possible to the report being built
on its basis, or to a initial document's form.
Linear Reading of Text Files
Operations on text files are the simplest data exchange mechanism. It can be
used for a wide range of tasks. The main advantages are simplicity in starting
using it and textual representation of information.
Developers can use the following features:
Create new and open existing text files, specifying one of the text
formats: UTF-8, -16, or ANSI;
Read a string of specified length, or the file entirely;
Read next string from the file, limited by a separator;
Write a text string to a file, with or without a separator.
XML
1C:Enterprise allows to establish integration with applied systems using
XML-documents, that is a commonly acknowledged data representation mean at
present.
Operation on XML-documents can be performed immediately from 1C:Enterprise 8
embedded language.
It is possible to:
Convert a string from an item's or XML-element's text into a value
according to the type specified.
Get string representation of a value to put to item's text, or XML
attribute's value.
Get XML data type according to the type passed as a parameter.
Check if the value of the type specified can be read from XML.
Write a value in XML format. The following values' types can be written to
XML: Undefined, null, Boolean, Number, String, Date, Type, UniqueIdentifier,
BinaryData, ValueStorage, TypesDescription, also data object references and
data object themselves, set of registries' entries, constant value manager.
The list can be updated later.
Return a type, appropriate to XML data type.
Using COM-connection and XML mechanisms one can arrange integration with
applied systems according to the formats accepted in the systems. XSL-conversion
mechanisms are used for this.
1C:Enterprise 8 includes extended features of working with XML and several
new object models are implemented, such as:
Implementation of object XML document model (DocumentDOM) corresponding to
the following standards: DOM Level 2, Xpath (Dom Level 3) and DOM Load and
Save (DOM Level 3).
Implementation of object XML scheme model (XMLScheme).
Capability to check an XML scheme correspondence when reading XML files.
Implementation of 1C:Enterprise 8 operation with XML is made on the base of
open source Apache Xerces and Apache Xalan libraries.
DBF-files
The mechanism allows to operate on DBF (dBase III) format data with
1C:Enterprise script language. It supports almost any operations on such data.
There is a special object in the system – XBase – to make it possible. The
mechanism allows to work on DBF format data from 1C:Enterprise script language.
In addition to supporting operations on existing databases, XBase object
includes a set of methods to create a new database of arbitrary structure, new
indexes and new index file.
It's worth to note that it's possible to use methods modifying a database
structure only for those objects which are not linked with existing database
(i.e. for new created databases only); while creation of new indexes and index
files is also possible for existing and opened databases.
COM-connection
The main task to be solved with COM-connection is to provide a reliable and
efficient way to access 1C:Enterprise 8 data from external applications. In
general, operation on 1C:Enterprise 8 through a COM-connection is similar to
working with it in Automation-server mode.
The main differences are the following:
In case with Automation-server, it starts a normal 1C:Enterprise 8
application, while with COM-connection relatively small in-process
COM-server is started.
When working through a COM-connection features, which one way or other
relate to 1C:Enterprise 8 user interface, are not available; When
COM-connection is being used, 1C:Enterprise 8 applied solution application
module does not work; external connection module acts as applied solution
application module.
There are following advantages in using a COM-connection before using
Automation-server to access 1C:Enterprise 8 data:
Quicker establishing a connection;
Quicker access to properties and methods of 1C:Enterprise 8 system
objects;
Less consumption of OS resources.
Automation Client/Server
The main goal of 1C:Enterprise 8 Automation-server is to control
1C:Enterprise 8 system application from other applications and performing
actions similar to interactive ones.
1C:Enterprise 8 Automation-server provides access to all properties and
methods of its global context.
Operation on HTML-documents
Means of operation on HTML-documents allow integrating them into an applied
solution's forms and editing them by means of the script language.
There is a control item - 'HTMLDocumentField' - in an applied solution's
forms to work on HTML documents.
An HTML-document can be build programmatically in a control item, loaded from
a resources at a certain URL, or from a HTML-template. It is possible to handle
events from the control item, including those from HTML document.
For example, there can be an HTML-document's field in an applied solution's
form to work on the applied solution's catalogs. Apart from other actions, such
form allows to browse catalogs' contents as HTML document and save the document
to disk.
Technology of External Components
It was developed for special integration tasks, where some close interaction
between 1C:Enterprise 8 system and other applications is required.
ActiveX
1C:Enterprise 8 framework allows embedding additional control items into
forms and spreadsheet documents supporting ActiveX technology.
ActiveDocument Templates
The technology is intended for editing documents by external software
editors.
Interaction over Internet
It is possible to do directly from the use script language. A developer can
use script language to send/receive e-mails and perform data exchange by HTTP(S)
and FTP protocols.
Hierarchical structure of data exchange
XDTO
XDTO stands for XML Data Transfer Objects. It is
a mechanism of data object modeling that is described by means of XML schema.
Main XDTO features are:
Description of parameters types and returning values of Web-services.
Data exchange between 1C:Enterprise 8.1 (and later) configurations with
other software with arbitrary data structures.
Data exchange on the base of XML schemas irrelatively to configurations
(for example, exchange with informational systems not built on 1C:Enterprise
8.1 (and later) framework).
Creating own system types and values to process optional data.
