DataWeb is Powerful Online Service that Business People use to create custom Cloud Data Base Applications quickly.
DataWeb Platform Features.
The following list gives an overview of the feature set of the DataWeb Platform.
Import/Export Capabilities
Access Database Import/Export
The DataWeb server can “upsize” an Access database to the DataWeb Platform. Views and navigation are created to allow users to instantly create a web-accessible custom relational database. Relationships between tables are preserved on both import and export.
CSV Import/Export
The DataWeb Platform imports and exports standard CSV files.
XML Export
Any query can be returned as an XML dataset from a URL.
Web Import
Given a URL, DataWeb servers can walk an existing web application, import pages, and fix up links within the pages. This gives users a quick start on porting web sites to DataWeb.
Integrated FTP Server
The Platform includes a custom FTP server that integrates with the DataWeb security model. This allows developers to publish content to their DataWeb application from existing web development tools such as HomeSite and Dreamweaver.
Archive Support
DataWeb can package an entire application as a zip file for easy archiving, maintenance and restoration.
Security Model
Secure Logon
All logons to the DataWeb system occur over SSL connections. The logon is preserved over standard HTTP connections and reauthorized via HTTPs at regular intervals.
Security and individual pages
All logons to the DataWeb system occur over SSL connections. The logon is preserved over standard HTTP connections and reauthorized via HTTPs at regular intervals.
Groups and Roles
DataWeb supports sets of permissions known as “roles”. Roles include Reader, Depositor, Author, Editor and Builder. These roles can currently be assigned to a fixed set of groups, though the underlying architecture supports custom groups.
Record-level security
The Author role allows groups of users to create records but limits their update privileges to the records they created. For example, I might be allowed to read the company address book, but only allowed to update my own address.
Helpful Data types and Objects
HTML data type
With the HTML data type, formatted text that is entered into a field is automatically converted to HTML. A graphical HTML editor makes it easy to format text to be stored as HTML.
File upload data type
The file upload data type uploads a file to a folder in your web application and stores a pointer to that file in your table.
HTTP Object
The HTTP client objects offer programmatic access to the data returned by a request to any web server. These objects make it possible to share data between a DataWeb web application and any other web site on the Internet.
Web Schema Objects
Web schema objects offer programmatic access to the structure of your web application and tables. Using script, you can create and modify tables, fields, and indexes.
Scripting
JavaScript (ECMAScript) Compatible
DataWeb uses a server-side implementation of ECMA compliant JavaScript that allows developers to build dynamic web applications using DataWeb’s extensive object model. Developers can use JavaScript to create business logic to drive an application, to generate custom pages based on user requests, or to programmatically manipulate data tables.
Object Model
The DataWeb object model includes the standard ECMAScript core object model along with a set of objects that are useful in a server environment. These include request and response objects, data and file system access, and user information.
Class Model
User-created DataWeb script files can be loaded as classes. New classes can be added to DataWeb without changing the core runtime.
Event Binding/Triggers
Scripts can be associated with database events and fired on insert, update, or delete of records.
Tag Embedding
Scripts that produce web pages or email often need to output large bodies of text. Like ASP and JSP, the script compiler can mix tags directly in the script for convenience of authoring.
Webcall
Functions within script files can be marked as “public”, “private” or “webcall”. Webcall functions can be called directly via a URL, allowing non-browser clients to automate DataWeb applications.
Views
Data Regions
Data regions are areas of a page that are bound to data. Data regions support filtering, sorting, and paging through data. Data regions can display data in grid, insert, update or details modes. Multiple modes allow a developer to create a single page and use it to serve different types of uses.
Template Pages
Template pages are an innovative way to give a group of pages within an application a common navigation “frame” and formatting.
Flexible Editing
The Builder has both a graphical editing tool that allows a developer to author views through the UI, and an editable source view, for direct editing.
Script Integration
Script can be used anywhere within a view to calculate and output values. In addition, script expressions can be used within many attributes on the server, to change how a page is rendered.
Auto Joins
Views can include data from multiple tables without exposing SQL or the concepts of joins. Users can add related fields to the display of any record and can also display "sub-lists" of related information.
