Object-Oriented Software Engineering by Stephen Schach

By Stephen Schach

Object-Oriented software program Engineering is written for either the conventional one-semester and the more moderen two-semester software program engineering curriculum. half I covers the underlying software program engineering thought, whereas half II offers the more effective existence cycle, workflow by means of workflow.
The textual content is meant for the titanic object-oriented section of the software program engineering industry. It focuses solely on object-oriented methods to the improvement of enormous software program structures which are the main commonly used. textual content contains 2 working case reports, elevated insurance of agile strategies and open-source development.

Software Synthesis from Dataflow Graphs

Software program Synthesis from Dataflow Graphs addresses the matter of producing effective software program implementations from purposes distinctive as synchronous dataflow graphs for programmable electronic sign processors (DSPs) utilized in embedded actual- time platforms. the appearance of high-speed pix workstations has made possible using graphical block diagram programming environments via designers of sign processing platforms.

Example text

In C++, a member of an object refers to either an attribute (“field”) or a method. In Java, the term field is used to denote either an attribute (“instance variable”) or a method. To avoid confusion, wherever possible, the generic terms attribute and method are used in this book. Fortunately, some terminology is widely accepted. For example, when a method within an object is invoked, this almost universally is termed sending a message to the object. Finally, we define the topic of this book. At the beginning of this chapter, we defined software engineering as “a discipline whose aim is the production of fault-free software, delivered on time and within budget, that satisfies the client’s needs.

Furthermore, it then may be necessary to modify the design as well, if the changes to the specifications necessitate corresponding changes to those portions of the design already completed. Only when these changes have been made can development proceed. In other words, developers have to perform “maintenance” long before the product is installed. 2. A second problem with the development-then-maintenance model arose because, some 30 years ago, a development team built a target product starting from scratch.

The other extreme is a product already delivered to a client. At the very least, correcting a fault at that time means editing the code, recompiling and relinking it, and then carefully testing that the problem is solved. Next, it is critical to check that making the change has not created a new problem elsewhere in the product. All the relevant documentation, including manuals, needs to be updated. Finally, the corrected product must be delivered and reinstalled. The moral of the story is this: We must find faults early or else it will cost us money.
