Seagull, a CASE tool, Design and
Implementation Integrated, the most revolutionary advanced
technology in Database Application Development to reduce your cost... |
Seagull
by NQLSoftware
Following
the requirement phase, developers have to design
business object model, design database schema, design presentation layer, design
business object layer... Once the
designs are reviewed and approved, implementation, the longest phase in software
development life cycle, begins. Developers create database then write codes to
save each piece of information from the form to appropriate field of a table in
the database. To do this, Developers must know the database structure, the data
type of each column in order to create the appropriate input controls, convert
the text input from the form to appropriate type, and have knowledge of ADO,
ADO.net etc. Developers must then
write SQL statements to save the data to the database.
Furthermore, if the database schema is modified, programmers must repeat
the process (a full SDLC) for each additional change.
To simplify the steps above, NQLSoftware developed Seagull, a
CASE tool that performs these tasks to save your developments,
your time, and thereby reduce your production costs.
Not only does the
Seagull design tool create business
object model easily
(Inheritance and containment supported), it also
-
creates database schema,
-
generates GUI (Win Form
and Web Form) and business object layer source code (C#, VB.net and VC++)
-
saves data to
database and load data from database without additional modification of the classes generated
GUI Classes
-
Win Form:
For each entity, Seagull creates a form (class) derived from GUIPersistence
containing the appropriate control for each attribute. The controls include but
are not limited to NQLSoftware custom controls e.g. NQLDatetimePicker,
NQLPictureBox, NQLFile, NQLGUID, NQLRefComboBox and also “Save” and “Close”
buttons (optional).
-
Web Form:
For each entity, Seagull creates a aspx file and codebehide (VS7) or
codefile(VS8) asps.cs (C#) or aspx.vb (VB), Codebehide and
codefile class derived from WebFormPersistence containing the appropriate
control for each attribute.
Business Object Model Classes
From your business
object model (diagram), Seagull also creates business object model
classes allowing you to traverse from one class to another via associations. It
also allows you to transfer data between class and database without having
knowledge of the database structure or writing SQL statements. For each entity,
Seagull generates a class. The class derives from ObjPersistence and has the
appropriate properties for each attribute of the entity and the appropriate
containment is referred to as an association (a object or a object collection)
and inheritance.
No need to write SQL statement.
GUI
classes and object model classes work together seamlessly.
Traditionally,
the approval of the design is just the beginning of the implementation phase.
But with Seagull, the approval of the design is near the end of the
implementation phase.
