Answer:
d. involves analyzing end-user business requirements in order to refine project goals
Explanation:
In the software development life cycle, the implementation stage is the stage where the computer programmers begin the actual coding of the application required by the end-user. At this stage, the developer takes into account the needs and specifications of the customer.
For example, if the end-user wants a software application that can track payment records, the researcher at this stage begins using the right software to code programs that can effect this function.

- The main purpose of using WAN includes a wide range, offers unified information, get upgraded files and software, several email sharing applications, etc.
Answer:
2^32 times as many values can be represented
Explanation:
32-bit. This means that the number is represented by 32 separate one’s and zero’s. 32 bits of 2 possible states = 2^32=4,294,967,296 possible values.
Integer meaning that only whole multiples of one are accepted.
Signed meaning that negative values are accepted. This halves the number of possible positive values (roughly), so the largest number you can represent is 2^31–1=2,147,483,647, but instead of 0, the smallest number you can represent is -2,147,483,648. An unsigned 32-bit integer, by contrast, can represent anything from 0 to 4,294,967,295.
It is true. RDBMS enforce integrity rules automatically. Integrity rules are automatically enforced by RDBMSs.
Integrity rules are automatically enforced by RDBMSs. Because it contains the design choices made regarding tables and their structures, a data dictionary is frequently referred to as "the database designer's database." Any character or symbol intended for mathematical manipulation may be contained in character data.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of RDBMS. Each table row in a relational database is a record with a distinct ID known as the key.
It is simple to determine the associations between data points because the table's columns carry the properties of the data and each record typically has a value for each property.
