Pretty much the same as between a robber and a victim, except the taxpaying "victim" has to save lots of data and fill in lots of forms _before_ he is legally "robbed" whereas the victim of an illegal criminal has to fill in the police report and insurance claim _after_ he is deprived of his money.
OK, seriously, the tax-paying entity pays tax to the government so the tax-paying entity is a remitter or payer or debtor and the government is a remittee or payee or creditor.

yes. For example, only one person actually "participates" in the stalker/victim relationship.
Entity means a specific thing in both database work and data modeling. An entity is data that can be classified, and has a relationship with other classified data, as in entities.
In software engineering, an Entity - Relationship model(ER model for short) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion. Diagrams created by this process are called entity-relationship diagrams or ER diagrams.learn more www.ngprakasam.hpage.com
An intersection entity is used in a database when there is a many-to-many relationship between two entities. It serves as a bridge table to resolve the many-to-many relationship by breaking it into two one-to-many relationships. Each record in the intersection entity represents a combination of records from the two related entities.
Entity-Relationship diagrams are useful for modelling data and the relationships between the data. They can be used when the constraints between data are relatively simple. They do not allow specification of interactions between the data or model how the data changes (there are no processes in Entity-Relationship). Entity-Relationship diagrams are most often used to model databases.
A relationship between instances of a single entity type is called a self-relationship or recursive relationship. This type of relationship occurs when an entity is related to other instances of the same entity type within the same entity set.
An entity relationship diagram for hotel reservation systems is a map of each entity or thing that has a part in the process of hotel reservations. The diagram maps the relationship between each entity of the process.
Degree the number of entity types that participate in a relationship.
An entity-relationship diagram for online banking includes the process of online banking and the relationship between each step. It is a model that maps out, describes, and defines how components are linked for online banking.

An associative entity is used to represent a many-to-many relationship between two or more entities in a database, while a relationship with attribute represents additional information or properties about the relationship itself. In other words, an associative entity helps in resolving many-to-many relationships, while a relationship with attribute adds details about the connections between entities.
Relation: In Database a relation represents a table or an entity that contain diffrenet attributes.An Entity constructs a relation(table) in DBMS . Relationship: In Data base relationship is that how the two entities are connected to each other ,i.e what kind of relationship type they hold between them.Primary/Foreign key is used to specify or hold this relationship.

An entity relationship diagram (ERD) represents the entities, or groups of information, and their relationships maintained for a business. An entity relationship diagram represents the entities, or groups of information, and their relationships maintained for a business. An entity relationship diagram represents the entities, or groups of information, and their relationships maintained for a business.
In contrast to the strong or regular entity, a weak entity is one that meets two conditions: 1. The entity is existence-dependent; that is, it cannot exist without the entity with which it has a relationship. 2. The entity has a primary key that is partially or totally derived from the parent entity in the relationship.
A child relationship refers to an entity or table that cannot exist without the existence of another entity or table. An example of this would be a table that is created to address a many-to-many relationship between two other tables.
