- EasyCASE
-
- An easy-to-use Computer Aided Software Engineering (CASE) tool
-
- EasyCASE is a limited function CASE (Computer Aided Software
- Engineering) tool intended to simplify the generation (with a certain
- amount of automation) of:
-
- Data Flow Diagrams (DFDs) - Yourdon/DeMarco and Gane & Sarson symbol
- support provided,
- Transformation Graphs (data/control flow schema diagrams) - Ward &
- Mellor and Hatley-Pirbhai real time extensions supported.
- State Transition Diagrams - Ward & Mellor and Hatley-Pirbhai,
- Structure Charts - Yourdon/Constantine and Page-Jones,
- Data Structure Diagrams - Jackson,
- Entity Relationship Diagrams (ERDs) - Chen.
-
- EasyCASE provides an easier to use, more automated method of producing
- these diagrams than does a presentation graphics or drawing program in
- that the drawing features provided are only those required to provide
- the symbols, connections, annotation and relationships required for
- the specific chart types implemented. EasyCASE is considerably less
- expensive and is also easier to use than most of the full-featured
- CASE tools in that it provides only the basic functions necessary for
- performing and presenting structured systems analysis and design.
-
- EasyCASE provides the capability to add the appropriate chart type
- objects (processes, stores, terminators, flows, functions, modules,
- couples, connections, states, transitions, entities, relationships
- etc.) to the chart and then manipulate them (move, delete, modify,
- label and describe etc.). EasyCASE maintains certain information about
- each object and also its relationships with other objects on the
- chart. Objects can be added, moved, deleted, labelled, identified and
- associated with other objects on the chart. If an object is modified
- in any way, any other similarly identified or associated objects on
- the chart are modified also. For example : (i) if a data process
- symbol on a transformation graph is moved, any attached data and/or
- control flows and their labels are moved also, remaining connected to,
- and associated with, the moved symbol; (ii) if a function symbol on a
- structure chart is deleted, any attached connections and associated
- data or control flow arrows (couples) and their labels are deleted
- also; (iii) if a previously defined labelled object identifier is re-
- used, the new object will inherit its label.
-
- EasyCASE interacts quickly and easily with the user via pop-up dialog
- boxes and menus and makes use of the mouse for selecting commands and
- working with objects. Color is used (EGA/VGA graphics cards only),
- particularly for highlighting selected and modified objects. EasyCASE
- provides a sizeable drawing area (equivalent in size to 3 sheets wide
- (approx. 24 inches) by 2 sheets high (approx. 21 inches) of A-size
- paper) and several zoom modes, scrolling around which can be performed
- using the mouse or keyboard.
-
- The whole chart or a specific area, selectable using the mouse, can be
- printed to a number of output devices which are compatible with the
- following; Epson FX, Epson LQ, IBM Graphics Printers, Hewlett-Packard
- Graphics HP 7475 and 7550 (HPGL) Plotters, QuietJet, LaserJet (HPLJ)

- and DeskJet printers. Charts can be printed at 100, 150 and 300 dpi
- resolution on HP LaserJet and DeskJet printers.
-
- Data Dictionary support provided by EasyCASE is minimal in that it is
- only provided at the chart, rather than at the project (related set of
- charts) level. Information entered about each object, and the
- relationship between objects, on each chart produced is exported in
- dBASE III file format so that reports and analysis can be performed
- using dBASE III Plus, Lotus 1-2-3, Microsoft Excel, PC-File:dB etc. A
- more powerful product, EasyCASE Plus is available and provides full
- data dictionary support, chart linking and much more.
-
- Charts can also be exported in Microsoft Windows Paint (v1.0 and v2.0)
- and PC Paintbrush (v3.0) file formats so that they can be incorporated
- into documents when using a desktop publishing or word processing
- program which can import Paint images, such as Pagemaker, Ventura
- Publisher, Lotus Manuscript, PFS:First Publisher etc.
-
- EasyCASE is intended to provide the end-user with a quick and easy
- introduction to the concepts of structured analysis and design methods
- and CASE which may then provide him or her with a basic knowledge of
- the methods and techniques required to implement the full CASE
- solution.
-
- EasyCASE requires an IBM PC (286 or 386 -AT recommended) or compatible
- equipped with a Hercules, EGA or VGA graphics card connected to a
- monochrome or enhanced color monitor, Microsoft mouse (or compatible),
- at least 512 kbytes of RAM. An Intel 80287 or 80387 math co-processor
- will improve the speed of screen updates, chart draws and printing.
-
- A SHAREWARE (fully functional evaluation copy, not a demo) version of
- EasyCASE, with similar capabilities as the registered version, may be
- obtained by sending $5 (to cover costs) to Evergreen CASE Tools
- (address below). This copy does NOT include registration, printed
- manual, upgrades or technical support. However, a disk based version
- of the manual (you print it) and some sample charts are included on
- the disk. If you find EasyCASE suited to your needs and intend to use
- it on a regular basis, you must register it by returning the enclosed
- order form. During the evaluation period, you will be expected to
- abide by the rules for Shareware product usage provided in the user
- manual.
