During the software design phase, the design document is produced, based on the customer requirements as documented in the SRS document. In other words, the user will have the information on what the object does instead of how it does it. Found inside – Page 328The style is used on the example . authors point out that the preferred code for this problem is Description : The high - level algorithm is Do 1 = 1 to N ... Data Abstraction Data abstraction is to collect essential elements composing to a compound data. They instruct computer programmers how to write the code they need. A sequence of instruction that contain a specific and limited function refers in a procedural abstraction. Encapsulation: Encapsulation is also called an information hiding concept. Because UML is a language to design code structure (i.e. GUI can be a combination of both hardware and software. In software maintenance, the following three levels of reverse engineering abstraction are defined: implementation abstraction, design abstraction, specification abstraction. 37.
