Digital Metaphors Report Builder Enterprise v12.03 Delphi 7 英文正式版(報表查詢設計軟體)
英文說明:
In ReportBuilder Enterprise, the goal is to deliver a
full-fledged reporting solution to end users. This goal is
achieved by delivering visual, easy-to-use solutions in
each of these four areas. This screen shot of the
ReportBuilder Report Designer shows the ergonomic design of
the user-interface.
Each of the four areas of reporting has a representative
notebook tab containing a visual environment for the
creation and configuration of components within that area.
The results of each area then become inputs to the next
area: data feeds into calculations, calculations feed into
components within the report layout, and the report layout
is rendered into a preview of the report. The
implementation used by ReportBuilder Enterprise for each
area of reporting is described below.
Data
Within the work environment of the Data tab, end users can
quickly create dataviews, which can then be used to supply
data to reports. Dataviews are usually created via the
Query Wizard or Query Designer. Both of these tools are
visual; they also allow the end user to select the tables,
fields, search criteria, and sort order necessary for the
report. Behind the scenes, an SQL statement is generated
and used to retrieve the data from the database. A screen
shot of a completed dataview is shown below.
The solution described above is the standard behavior
within the data workspace. However, the developer can
customize this user-interface by doing one of three tasks:
1. Register a replacement query wizard or query designer.
2. Remove the query wizard or query designer.
3. Create new dataview template classes that can simplify
the data selection process even further by establishing the
relationship between the tables in the database and
presenting an alternative user-interface (such as a single
form that allows search/sort criteria to be entered).
The bottom line is that the Data area contains a turnkey
solution that can be used out-of-the-box, but if
customizations are needed, an architecture has been
provided so that those customizations are possible.
Calc (RAP)
The Calc workspace is used to manage the RAP code
associated with the Report. The Calc workspace contains a
tree view of the report, all the bands within the report,
and all the objects within each band. When a band or
component is selected, all the events for that component
are shown in a list. The user can then select an event and
code the event handler in the syntax-sensitive code editor
at the bottom. The following screen shot shows an OnPrint
event as coded for a Line component.
This screen shot shows the Calc workspace in its most
feature-rich and complex configuration. Development work
completed here can be passed on to end users so that they
can modify it, locked down so that end users can only view
it, hidden completely so that end users do not know it is
there. The most scaled-down version of the Calc tab is
provided by the dialog only interface, where no Calc tab
exists at all, and a single syntax-sensitive code-editor
dialog is accessible from the Calculations? menu option of
the variable component. The user-interface and
behind-the-scenes architecture has been made highly
scalable in order to meet the various needs of developers.
Design
The Design workspace contains the actual layout of the
report. The user-interface is identical to the one
presented to developers using ReportBuilder at Delphi
design-time; in other words, it is full-featured and
professional. The
Office97 interface-style makes the Design
workspace especially easy to learn for end users. A Report
Wizard is available for creating reports quickly. You can
customize this interface by replacing any of the dialogs it
uses and by registering your own report wizards.
Preview
The Preview workspace contains the rendered report. The
report can be printed to the printer or to various file
formats from this workspace.
