What is the Entity-Relationship Model?

ER diagram is a model in DBMS which is used to represent the relation between real-world entities. In this tutorial, we have explainedthe er diagram with examples. This Diagram shows the conceptual view of a database at any instance of time.

ER Model shows how different entities are related to each other in any system. Peter Chen introduced the ER Model. In his paper "The Entity Relationship Diagram" – Towards aUnified View of Data, he explained this model.

ER diagrams are the diagrammatic representation of the Database Designs. So, they are mainly used to designRelational Databases. Also, they are used during the planning stage of anySoftware Engineering Project.

er diagram examples

Components of ER Diagram Examples

Some major components of an er diagramexamples are as follows.

  1. Entity : Any real-world objects came under the category of entity. An entity can be any person, any object, any place, or event relevant to a given database system.

Examples:  A Pharmacy Management system can have entities such as drugs, cash, injections, bills etc.

There is a kind of entity that depends on the existence of other entity & that is known as theWeak Entity. Entities are represented using Rectangles.

  1. Attribute –  They are the properties through which an entity is defined. Suppose there is an entity called Student, thenStudent'ss name, Student's age, Student's email address, Student's phone number came under the category of the attribute of the entity" "Studen""

There is the following kind of attributes:

  • Simple attribute: Attribute whose values are already atomic & cannot be divided further. For example, The first name & last name of an entity "Student".
  • Composite attribute: Attributes that are made up of more than one simple attributes. For example, The attribute 'Name' contains First Name, Middle name and last name etc.
  • Single valued attribute: These attributes contain only single values. For example, The attribute "Age" of an entity "Student."
  • Multi-valued attribute: These attributes contain multiple values. A double oval represents t. Forexample' 'Phone Number" of an entity" "Student."
  • Derived attribute: The attributes derived from other attributes & are not present in the database system are known to be called Derived Attributes. For example, The 'Age' of the entity 'Student' can be derived from the attribute "Date of Birth". So age is the derived attribute. A dotted oval represents a derived attribute.
  1. Relationship: Relationship represents the association  among the entities of an ER diagram. The diamond symbol represents it.

ER Diagram Notations and Symbols

Different er diagram examples, notations and symbols are shown in the following figure

er diagram examples

Relationships between Entities

If there are more than one entities in a DBMS, then there is a more chance that all the entities are related to each other through some relationships.

These relationships are represented using a Diamond Shaped Box, and as usual, entities are represented using Rectangular Box. All the entities in a relationship are connected using a hard line.

When two entities are connected, then it is known as Binary Relationship. The number of instances of any entity associated with any other relation is known as Cardinality of the Entity.

Relationships are the association between the entities. There are four types of the cardinality of a relationship:

  1. ONE TO ONE

In one to one mapping cardinality, an entity in an entity set A can be associated with at most one entity in another entity set B. An entity in set B can be associated with at most one entity in set A.

er diagram

Example:  One Student can enrol in at-most one course, or one course can be enrolled by at most one Student.

  1. ONE TO MANY

When an instance or entity in an entity set A is associated with any number (zero or many) of entities in other entity set B or an entity in entity set B is associated with at most one entity in the entity set A, then this type of relationship is known as one to many relationships. Mainly''Man" or" should be on the right side of the relationship.

Example:  One Student can enrol in any number of course ( including zero), or one course can be enrolled by at most one Student.

  1. MANY TO ONE

When an entity or instance of an entity set A is associated with at most one entity in other entity set B or an entity in entity set B can be associated with any number of entities of an entity set A, then it is known as one to many relationships. Mainly''Man" or" should be on the left side of the relationship.

er diagram examples

Example : One student can enrolled in at most one course or one course can be enrolled by any( zero or many) students.

  1. MANY TO MANY

When an entity in an entity set A is associated with any number of entities in an entity set B and vice versa then this type of cardinality or mapping is known as many to many. Mainly 'Many' or 'N' should be in the both side of the relationship.

er diagram examples

Example: One student can enroll in any number of course ( zero or many ) or one course can be enrolled by any( zero or many ) number of students.

ER Diagram Examples with Solution

An ER diagram for Customer and Loan entity is as shown in following figure.

Relationship between customer and loan entity set is borrower. It means customer borrow the loan. Different attributes of customer and loan entity are also shown.

Customer_id is the key attribute of Customer entity similarly loan_id is the key attribute of loan entity.

er diagram examples

ER Diagram Keys

In ER Modelling, Keys are used forindexing. Through keys, one can easily access any row without wasting much time and efficiency. It is very usable in tables which millions of data or rows. Let's take an example of a table" "EMPLOYE" with the fields" "EMP_ID, EMP_F_NAME, EMP_L_NAME, EMP_PHNO, EMP_EMAI".

Basically, there is 4 type of keys which plays a major role in ER Modelling, which are as follows:

  1. Primary key:  It is that column of a table that has all the unique values inside it. Through the primary key, the data in the table will be identified uniquely.

Example. In a table" "EMPLOYE", the" "EMP_I" (EmployeeID), which is assigned to every Employee uniquely, is known to be the primary key of the table.

  1. Composite key

When two or more attributes are combined to form a primary key column or identify any table data uniquely, this is a composite key.

Example. In a table" "EMPLOYE", the" "EMP_PHN" &" "EMP_EMAI" attributes, if combined, form a type of primary key which is assigned to every Employee uniquely, is known to be the composite key of the table.

Participation Constraints in ER Diagram

There are twotypes of participation constraints, and these are as follows.

Total Participation

In total participation, each entity is involved in the relationship. Double lines in the ER diagram represent total participation. Total participation specifies that each entity in the entity set must compulsorily participate in at least one relationship instance, the relationship set.

Total participation sometimes is also known as mandatory participants.

Total Participation Example – In the following figure Double line between the entity set" "Studen" and relationship set" "Enrolled i" signifies total participation.

er diagram examples

Partial Participation

In this types of participation not all entities are involved in the relationship. Partial participation is represented by single line. It specifies that each entity in the entity set may or may not participate in the relationship instance in that relationship set.

That is why, it is sometime also known as optional participation

Partial Participation Examples


er diagram examples

Here in this example Single line between the entity set "Course" and relationship set "Enrolled in" represents partial participation. It specifies that there might exist some courses for which no enrollments are made.

Volkswagen Golf III | Fuses and relays

14.2. Fuses and relays

The location and purpose of the relay and fuses depending on the vehicle modification may differ. The designation of the controlled and protected electrical circuit is applied on the block lid.

The main unit is located in the rear of the engine compartment by the driver. The additional unit in cars manufactured before 01.1991 is located above the broad box, and in cars manufactured from 01.1991 in the back of the motor compartment from the passenger side.

Relays can switch strong currents at a distance, allowing you to use weak control switches and wiring.

In contrast to mechanical switches, relays can be controlled by more than one signal.

Some relays can function on a timer, for example, in the intermittent mode of operation of wipers or heating windshield.

If a malfunction is detected in the circuit, equipped with a relay, it should always be remembered that the problem may be in the relay. Check can be replaced by a well-serviceable relay.

To replace the relay, remove it from the socket and insert a new one. Access to the relay in the main box is carried out in the same way as the fuses. Access to the relay located under the instrument panel is carried out after removing the upper part.

Luke Drive Relay is located in the upper console.

CIRCUIT BREAKERS

The battery is protected from a short-circuit fuse from a positive pole.

The main fuse block and the relay is located on the right in the engine compartment, near the partition. It contains up to 24 fuses and almost as much relays (depending on the equipment). The list of fuses is located on the back of the block cover.

In the car there is an additional fuse block, access to which is possible after opening the lid of the discharge box.

The fuse for the radio receiver is located on the power supply of a radio receiver under the front panel on the left side near the heater.

All knife type fuses and have a color corresponding to a specific fuse protection. The safety of the fuse is determined by the presence of a wire conductor connecting the contacts of the fuse.

To replace the failed fuse, it is necessary to pre-turn off the corresponding electrical circuit. Remove the failed fuse from the nest using tweezers or special grips.

In the event that the newly installed fuse instantly fails when the voltage is supplied, the protected electrical circuit should be checked. If the fuse protects at the same time several electrical circuits, they must be connected in turn in order to determine the faulty chain to determine the faulty chain and then eliminate the fault.

In some electrical circuits, such as electrical engine drive engines and seat position regulators, instead of fuses are installed thermal relays that are automatically switched on after elimination of overload.

Volkswagen Golf III | Circuit breakers

Circuit breakers

The protection of the electrical circuits of the car is ensured by using a combination of fuses, circuit breakers and fused inserts. The burned fuse is easily distinguished from a serviceable inspection of its transparent plastic housing. Carefully inspect the fuse for the detection of its brave. If the fuse appears normally, but suspicion of its malfunction is preserved, check the conductivity between the knife terminals protruding from its housing.

When replacing the fuses, monitor the correspondence of the replaceable old type. Fuses calculated for different strengths may appear to look identical, therefore, special attention should be paid to marking. Replacement of the burnt fuse on a smaller calculated - and especially greater - current strength is undesirable. Each electrical outline needs varying degrees of protection. Make sure that the marking on the fuse body corresponded to the strength of the current on which the corresponding contour is calculated.

If the replaced fuse immediately burns out, it is not reasonable to continue its replacement. First, it is necessary to identify and eliminate the cause of his knocking out. In most cases, it turns out to be a short circuit of the circuit wiring caused by a cliff or damage to the insulation of the wire. The fuse bursts the electrical circuit when the current reaches the set value. Thus, the current consumer is protected and its chains from damage. With a short closure, for example, the fuse is melted, protecting the chain.

The location of the relay is the same for all versions regardless of the year of release. Functional fuses are different. The main fuses and relays are in the block, like shown in the illustration. It should also distinguish blocks depending on the models of engines and years of release.

The location of the fuses in the block is equally for all versions regardless of the year of release. Functional fuses are different. The illustration shows the car fuses until the end of 1995. The power of the nominal current of the fuses is shown. Fuses protect the following chains: 1 - F10E, rated current 10 A, left headlamp, light range adjustment, Far light control lamp2 - F9E, Rated current 15 A, right headlight, Middle Light 3 - F8E, Rated current 15 A, fog light4 - F7E, rated current 20 A, fan5 - F6E, rated current 15 A, fuel pump (engine 2.0 l until mid-1995 release and engine 2.4 L) 6 - F5E, rated current 10 A, FAROMIMER7 - F4E, rated current 10 A , audible signal8 - F3E, rated current 10 A, alarm9 - F2E, rated current 10 A, Parking light and rear light Light, Devices panel lighting, Switch and cigarette lighter10 - F1E, Rated current 10 A, Parking light and rear light Right

Separately located fuses are located in positions (11) and (12). The fuse (11) has a rated current of 60 A and is indicated by F11E. This is the main fuse. The fuse (12) has a rated current 30 A and protects the headlight, turn signals and alarm alarm and diagnostic shoe.

Block relay / fuses of models between the middle of 1995 and the end of 1997. The release corresponds to the location of the fuses in the block. Some fuses perform other functions: 1 - F10E, rated current 10 A, left headlamp, light range adjustment, Far light control lamp2 - F9E, Rated current 15 A, right headlight, Middle Light3 - F8E, Rated current 10A, fog light4 - F7E , nominal current 25 A, fan, air conditioner compressor coupling5 - F6E, rated current 25 A, fuel pump (engine 2.0 l and 2.2 l from mid-1995 release) 6 - F5E, rated current 25 A, early release cars, 30 A Late Release Cars, Faromer, Sound Signal, Engine Diagnostics7 - F4E, Rated Current 30 A, Air Conditioner Fan, Right8 - F3E, only for diesel engine9 - F2E, Rated current 10 A, Parking Light and Rear Lamp Left, Device Panel Lighting, Switch and cigarette lighter10 - f1e, rated current 10 A, parking light and rear lights right11 - FL3, rated current 30 A, parking light and rear lights FL4, rated current 30 A, radiator fan12 - F L1, Rated current 60 A, FL2 main fuse, Rated current 60 A, Headlights, Engine secondary air supply system 2.2 liters (from mid-1995 release).

Fuses can be replaced. At the same time, it is necessary to install a new fuse of the same nominal current. It is also important to identify the cause of the fuse brave. Fuses have a color marking.

As you know, the fuse block is responsible for the operation of all electrical devices of a car tied to the chain. Therefore, the performance of these elements determines the operation of not only secondary devices, such as light in the cabin or cigarette lighter, but also primary, in particular, light headlights or gas station. Today you will learn where Golf 2 fuse block is located, the elements are responsible for the work of any devices and how to replace BP.

  • Introduction

    Introduction

    Volkswagen Golf Third Generation debuted in August 1991 at the Geneva Motor Show. And next year, a version in the body of a sedan appeared under its own name Vento.
    Given the "Nativity" of the car, the leadership of the concern decided to try to meet the needs of a very wide range of consumers, which is why the line of the body included three-door and five-door hatchbacks, the Golf wagon with the additional name Variant, and a convertible. It is worth noting that the capacity of the station wagon was almost the best among all classmates. Thus, the volume of the luggage compartment when the rear seat back was 1425 liters.

    The sedan from the hatchback was practically not distinguished: the original headlights of the head lighting, the radiator grille and, of course, the trunk, which is assigned its own compartment.
    By virtue of constructive features, the car in the four-door version turned out a little more than five-door "fellow". All from a technical point of view (up to the gamma of the engines) at the hatchback and the sedan is almost identical.

    Golf III received a different design and more spacious interior. Among the additional equipment of the car, you can highlight the ABS system, the electric heating of the seats, air conditioning, the electric drive adjustment of the seat back of the seatback, the central lock, the servo adjustment of the outer mirrors, the engine pre-warming system in the cold time and much more, which could only be in the early 1990s .
    The gamut of the engines was six gasoline aggregates (from the 60-strong 1.4-liter to a powerful VR6 12V of 2.9 l / 190 liters. P.) And three diesel engines (two atmospheric 64 and 75 liters. And one with turbocharging With a capacity of 90 l. p.). All gasoline engines were completed with the neutralizers, which was partly in the wonder for cars of this class in those times. The most powerful versions received a four-step automatic transmission with an electro-hydraulic drive, equipped with two programs - for economical and sports styles of driving. Also, sports versions could boast disk brakes on all wheels (front - ventilated). Everything, without exception, cars were completed with an amplifier of the steering mechanism.
    In 1995, a version with a very powerful 2.8-liter engine (with a capacity of 172 liters) under the hood appeared. Install the engine of this volume in a relatively small car managed due to its compactness - thanks to the VR6 scheme.
    The period in which the Golf III / VENTO appeared is marked by a more detailed study of the passive safety of cars as a whole. Therefore, this model is characterized by special deformable areas with zones, enhanced frame built into the doors amplifiers. Also, the car could have been equipped with airbags for the driver and passenger on the front seat and deformable on a 170 mm steering column. Engineers who created the Golf III / VENTO were given to customers a 12-year warranty from end-to-end corrosion of the body.

    This manual provides instructions on the operation and repair of all modifications of Volkswagen Golf III / VENTO, manufactured since 1991.

Action in Emergency Situations Volkswagen Golf 3 / Vento since 1991 Replacing fuses

4. Replacing fuses

Electric car chains each individually protected by fuses.
The central mounting unit with the relay and the fuses are located under the lid below the pedals of the car control.

How to replace the fuse

1. Turn off the corresponding current consumer.
2. Remove the lid. To do this, click on both keys, pull the cover from the front down and remove it.
3. Using the fuse list, set which fuse refers to the refusable current consumer.
4. Remove the appropriate fuse.
5. Burned fuse, which can be determined by the particles of molten metal scattered along its walls, replace the new fuse, calculated on the same current.
6. Insert four protrusions of the cover behind in the trim and, taking the cover behind the front part, turn it up to a reliable fixation in the closed position.
Note:
If the newly installed new fuse is over a short period of time, it is necessary to check the current consumer in the Volkswagen service enterprise as soon as possible.
In no case cannot "repair" fuses, because because of this, serious problems may occur in other elements of the car electrical system.
Some of the current consumers listed below include only certain versions of the vehicle or are custom equipment.

Color marking fuses

Light brown - 5 amps.
Red - 10 amp.
Blue - 15 amps.
Yellow - 20 amps.
Green - 30 amps.

\u003e 9.6. Side Electrical Network\u003e Mounting Block

The mounting unit is located on the driver side, at the bottom of the front panel. It serves to accommodate fuses, basic relays and to attach wiring beams. Fuses are located under the lid of the fuse block.

1. The main fuses are located under the relay, in one row. Chains protected by each of the fuses are shown on the block cover. On some models there are additional fuses installed in separate holders located or over the relay, or in the engine compartment.

2. Inside the fuse should be visible. If the fuse blocked, this wire will either be broken or melted.

When replacing, always install a fuse that has the same nominal characteristics that the previous fuse has been. Never use a fuse with other nominal characteristics and do not replace it with any other detail. Never replace the fuse more than once, without finding out the cause of the fault. The nominal characteristics of the fuse are indicated on it from above. To facilitate the recognition, fuses also have a color marking, depending on the strength of the current: beige - 5 A, red - 10 A, blue - 15 A, Yellow - 20 A, green - 30 A.

If the fuse protects more than one chain, try to localize a malfunction, including each chain separately (if possible) until the fuse has happened again. Always have spare fuses on the car all the necessary denominations - one samples of each denomination must be attached at the base of the fuse block.

On vehicles with diesel engines, the electric circuit of the power supply of the sloping candle is protected by melting insert. At all the first models, both with gasoline and with diesel engines, in the circuit on the cooling fan of the radiator also there is a fusible insert.

The location of the relay and fuses on the front side of the mounting unit is represented in Fig. 9.18.

If a circuit or system, controlled by a relay, are faulty and can be assumed that it is defective to the relay, then turn on the system. If the relay is functioning, then clicking when it is triggered. If this is, it is faulty system elements or wiring. If the relay does not work, the supply voltage or control voltage is not fed to it, or the relay itself is defective. To check, replace the checked relay on knowingly good, but be careful - keep in mind that relays that look similar are not necessarily identical in characteristics and functions performed. An identification number is applied on the case of each relay, which does not match the number on the mounting block panel indicated in the rectangular frame in the diagrams. The designation and purpose of the relay are presented in
