They also may include requests for drill down reports, which show a greater level of detail; key-indicator reports, which summarize the performance of critical activities; and comparative reports,which compare performances of different department...

The entity-relationship model (or ER model) is a way of graphically representing the logical relationships of entities (or objects) in order to create a database. It uses ER diagram to document the conceptual data model. ER diagram consists of entities, attributes, and relationships and cardinalities.  • Entity: An entity can be a real-world object, either animate or inanimate, that can be easily identifiable. For example, in a school database, students, teachers, classes, and courses offered can be considered as entities. All these entities have some attributes or properties that give them their identity. • Attributes Entities are represented by means of their properties, called attributes. All attributes have values. For example, a student entity may have name, class, and age as attributes. • Relationship The association among entities is called a relationship. For example, an employee ”works at” a department, a student ”enrolls” in a course. Here, ”Works at” and ”Enroll...

Network Topology is the schematic description of a network arrangement, connecting various nodes(sender and receiver) through lines of connection. Some basic types of Network topology are : Bus Topology: • Bus topology is a network type in where every computer and network device is connected to single cable. • It transmits data only in one direction. • Every device is connected to a single cable • It is cost effective. • Cable required is least compared to other network topology. • It is used in small networks. • It is easy to understand. • It is easy to expand joining two cables together. • Cables fails then whole network fails. • If network traffic is heavy or nodes are more the performance of the network decreases. • Cable has a limited length. • It is slower than the ring topology. Bus Topology Ring Topology:  • It is called ring topology because it forms a ring as each computer is connected to another computer, with the last one connected to the first. Ex...
