Different types of data models

Data modeling is a process of creating data models for storing in the databases. It is a conceptual as well as a visual representation of various data that are significant and related to a business enterprise. It consists of information, rules, compliances, policies, securities, value, and semantics that are important for a business.

There are three types or stages of data models:

  1. Conceptual Data Model
  2. Logical Data Model
  3. Physical Data Model

Conceptual Data Model

The conceptual data model consists of entities and relationships between entities. The conceptual model provides an overview of the data and is highly abstract; that is the data presented in the conceptual model are general rather than specific. One does not need software to create a conceptual data model as it can be drawn on any piece of paper. One can make diagrams using boxes and lines to represent entities and relationships respectively.  For example; let us take four boxes and name them Time, Product, Sales, and Store, and draw a line linking Time and Product with Sales and sales with the store. Thus, a conceptual model of the data is ready.

The conceptual model consists of the semantics of the data; that is ‘what’ of the data. It does not indulge in descriptions and metadata; rather it shows the relational data between entities. 

Therefore, the conceptual model is highly abstract and consequently easy to understand. They can be easily enhanced as only entities and relationships are visible. One does not require software to create conceptual data models.

Logical Data Model

The next stage is the Logical Data Model. Logical Data Models are an expansion of Conceptual Data Models. It is more descriptive than conceptual models as it includes attributes or characteristics of the entities. The presence of attributes for each entity makes logical models more detailed. The construction of the Logical Data Model consists of Key as well as Non-Key attributes, and a relationship between Primary and Foreign Key attributes. If we have to build from the conceptual model created above for our logical model, it would have attributes such as time, date, month, and year (and more) in the time box. Product id, description, category, price, etc. in the product box. Items sold and sales amount in the sales box and region, store description in the storage box. The sales box will also contain Foreign Key (primary keys in other entities) attributes.

The logical Data Model has more descriptions than Conceptual Data Model. It has user-friendly attribute names and takes more effort to enhance. Logical Data Model requires software programs such as ERWin for construction.

Physical Data Model

Physical Data Models are an expansion of Logical Data Models. It consists of meta-data and has all the information regarding the business. These models can only be designed with the help of software such as ERWin, and the nomenclature of entities and their attributes are changed to tables and columns. These names are database compatible and are not user friendly as only technical people can comprehend it. It is difficult and requires more effort to enhance.   


Personal bankruptcy is a legal action that takes place when the person or a company defaults on the loans. When a debtor is not able to pay the exceptional loans, a petition is filed in the court. This petition is usually submitted by the debtor, but it can also be submitted on behalf of the loan providers.

The personal bankruptcy procedure involves analyzing every possession of the debtor that can be used for repayment of the debt. After completion of the personal bankruptcy process, the debtor is alleviated of all the financial obligation responsibilities, and the financial institutions get partial or full payment of the loan.

Description of Personal bankruptcy

The insolvency procedure allows the debtor to get relief from debt responsibilities. The treatment eases the problem of people and corporations in making debt payments. It also enables creditors to get payments that are based upon the available asset of the people.

A bankruptcy procedure begins with the filing of a petition in a court. The petition can be filed entirely by a private, and jointly by both the partners, and by a legal agent of a company. Declare insolvency can enable a business to continue its operations, and pay the debt responsibilities during alarming financial times.

People gain from personal bankruptcy filing in the sense that it relieves the financial obligation payment problem, allowing them to satisfy important financial costs, when they are dealing with monetary problems. People can file for insolvency through a lawyer or by themselves. When the specific declare bankruptcy by themselves, it is called filing pro se.

Kinds Of Bankruptcy Protection Plans

In the United States, all the bankruptcy cases are filed in federal courts based on the U.S. Insolvency Code. The code defines different type of insolvency defense plans such as Chapter 7, Chapter 9, Chapter 11, Chapter 12, Chapter 13, and Chapter 15.

Business submit chapter 7 to liquidate the company, while chapter 11 is submitted to rearrange the organization. Chapter 9 is submitted by towns including villages, towns, cities, taxing districts, school districts, and local energies to restructure. Chapter 12 provides relief to farmers and fishermen, while Chapter 15 involves cases that include celebrations outside of the United States. Chapter 13 is also understood as an employed individual’s strategy that allows an individual to establish a plan to pay the entire or partial financial obligation quantity.

Main Forms of Test Questions

There are a number of types of multiple-choice test formats, and guys from Wedoessay blog are going to tell you about each of them. So, with the help of this information, you will know how to vary the forms of testing and create the tasks for every part of your test properly. You should also remember that every question/task needs to have the following parts:

  • Instruction (on how to do the task);
  • The content of the task;
  • Variants of answers;
  • Evaluation.

Choose One Correct Item

This task consists of the task which has only one correct answer, and a few more incorrect answers are offered to confuse the student. Those incorrect close-to-correct answers are called distractors by their actual function in the exam test. There are two groups of composition for such tasks.

Principles of composition for the content of the exam test task

Here are the principles that need to be mentioned in this category:

  • Principle of homogeneity: the answers in such tasks should be homogeneous concerning their form and visual features.
  • Principle of negativity. This is when the second answer is formed simply by adding “not” to the previous one. This “not” gives negative sense not to the task, but to the previous answer.
  • Principle of alternative. This is when two answers are opposite to each other.
  • Principle of supplementation. This is when each next answer has an extra element in addition to the previous one.
  • Principle of a chain. This is when the ending of the previous answer is the beginning of the next one.
  • Principle of gradation. This is when the answers are organized based on the increase or decrease of a certain quantitative feature.
  • Principle of double alternative. This is when each one answer consists of 4 items, parts of which are built based on the principle of alternatives.

Such questions have the following advantages: clarity of interpretation, exact structure, high speed of exam testing process, objectiveness. There are also a few disadvantages, namely: a lot of time spent on creating a qualitative exam test, complexity of the search for appropriate distractors, low effectiveness in evaluation of possibility to resolve issues, limited possibility to express oneself.

Choose a Few Correct Items

The construction of such type of tasks is pretty much the same as for the previous types. The probability of guessing a few answers is much lower though. To formulate answers, one needs to apply distractors and correct answers. The tasks with a few correct answers are considered to be completed properly if all the correct answers have been found. One can change the system of evaluation and add points for each correct answer found. It is necessary to inform the students about the set system of evaluation before the beginning of the exam test.

Choose One Full and Correct Item

Here you can see correct complete answers and correct incomplete answers. A student is required to find the best and the fullest answer to choose.

Additional Requirements and Recommendations for Task Formulation

Here are some more tips for successful accomplishment of the task for exam, where students need to choose one of a few correct out of suggested variants.

  • There must not be any ambiguity or unclearness in formulation of the task.
  • The task needs to be short, better a one-sentence-long simple syntactic construction.
  • If the answers start with the same words, it is better to add them to the task and remove from answers to avoid repetition.
  • All the answers should be more or less the same in length.
  • It is necessary to remove all possible verbal associations from the task if they may point out to the correct answer.
  • One must not use the exam, where an answer may be understood based on the previous tasks.
  • It is prohibited to use the tasks which are aimed at subjective evaluation or require a personal opinion on certain issues.
  • All the distractors should be similarly attractive for those, who do not know the correct answer.
  • No distractor can be a partly correct answer, which can be taken as correct under some circumstances.
  • All the variants of answers should be in a grammatical correlation with the task of the question.

In our next article, we will discuss the principally different type of multiple-choice exam test tasks.

¿Tipos de préstamos con asnef?

nullPodemos diferenciar entre los prestamos rapidos con asnef y aquellos que se pueden firmar sin tener que avalar.

Que decir tiene que los préstamos rapidos con asnef con aval son los habituales siendo los préstamos personales con asnef minoría en el mercado.

Si nos podemos a pensar en financieras que puedan firmar préstamos sin aval con asnef nos daremos cuenta como casi todas ellas no suman más de 5.

Algo triste pero que actualmente es lo que hay.

A pesar de que los préstamos de capital privado son los créditos habituales para salir del asnef incluso ellos lo tienen difícil a la hora de poder dar salida a todos los clientes.

Las solicitud de cada persona son muy diferentes entre si de ahí que la financiera tenga que intentar adaptar los préstamos con asnef de los que dispone a la situación de los mismos.

Y no es fácil, sobre todo cuando los clientes están buscando conseguir esta financiación mediante préstamos personales.

Préstamos con asnef y aval aportado

Son los habituales  al hablar de préstamos para salir del asnef.

Los avales usados por los clientes son de todo tipo aunque aquí también hay que tener claro que no todas las financieras los aceptan como garantía.

No vamos a explicar las diferentes tipos de financieras privadas que realizan estos créditos pero os diremos que lo habitual es que cada una de ellas este centrada en un solo aval.

Alguna de estas empresas de capital privado están centradas en firmar préstamos hipotecarios, otras en cambio lo que hacen sobre todo son préstamos sobre coche, otras pueden aceptar avales más “raros” como  barcos, obras de arte…

Pocas son las financieras que tienen préstamos con asnef en donde los clientes pueden aportar cualquiera de estos avales.

Y se entiende debido a la gran cantidad de gestiones que las financieras tienen que hacer en cada una de estas operaciones.

Tramitar un préstamos rápidos con asnef no se hace de un día para otro, si además son distintos avales los que puede aportar el cliente el trabajo para la financiera será doble.

Perfection in the Perfect Usage of the Scrap Metal Now

Private households produce a lot of waste from scrap metals. Light metals such as aluminum or empty cans are recycled through the separately collected lightweight packaging. Especially with a budget resolution, a lot of metal scrap is generated. Scrap metal must not be released via the bulky refuse – you will find information on bulky refuse here. The metals must be disposed of separately as they can be separated, melted down and then reused. For bulky metal wastes, most waste disposal companies offered a collection of waste metal or the disposal through recycling centersrecommended. There you can easily dispose of your scrap metal via containers. Scrap metals from the household sector have a recyclability of up to 60 percent.

Picture old, broken bike

Old bicycles consist almost exclusively of metal and therefore belong to the scrap metal.

Sale of scrap metal

After scrap metal there is a growing demand, as the treatment of scrap metal is becoming cheaper. By contrast, higher production costs or production of the corresponding type of metal lead to higher raw material prices. If larger quantities of scrap metal are to be delivered, then considerable prices can be achieved on the scrap metal market or at the scrap merchant – depending on the metal and the daily price up to several thousand euros per ton. The prices of scrap metal are subject to various factors and therefore cannot be determined precisely. It also depends exactly on the type of metal, currently, for example, copper is in great demand. With the options famous for used scrap metals that are you can get the best deals.

Also the quality

So the amount of pollution plays a role in the price.

Scrap metal recycling

Aluminum cans are collected, pressed and then recycled.

Thus, the resources are spared and at the same wastefully recycled. Due to separation and recycling processes for almost all metals and the resulting significant energy savings compared to the new production, the separate collection of scrap metal is an important contribution to a sustainable economy. You can also do your part by properly sorting and disposing of your waste. From the reputable signage company in singapore you will get to know a lot.

Font selection for signage

Not important for what you need a sign: for the store, cafe or beauty salon. These rules are important to all of them.

  • The first thing we were interested in choosing the font. Therefore, we began a conversation with designers with the question: “What font to use and what size?”

If the required text consists of a single sentence, use a font of the same size. If there is a few lines on your sign (for example, on an information plate or three-dimensional letters), then the interval should not be made more than twice as large as letters. A great example would be the 17th century plaque.

Risk free battery recycling essential now

The transition from landline to mobile has given a huge boost to the development of electric storage. Electrification everywhere – also in mobility. The core element of electric cars is not just the power, but also the memory (battery or rechargeable battery), which absorbs this energy and gives it to the vehicle.

Imagine the battery storage of the electric car like an oversized cell phone battery. The terms “accumulator” and “battery” are colloquially used side by side and often synonymous. Although it is strictly speaking wrong. Rather, it should read: A battery is a primary cell and can not be charged. A rechargeable energy storage such as the battery in the electric car is not a battery, but a secondary cell.

Strictly speaking, what drives the electric car, physically correctly designates a “traction battery from a few to thousands of parallel and serially interconnected accumulator cells” (Wikipedia) – mostly installed in the vehicle floor and many, many kilograms. From the Kinsbursky scrap yard get the opportunities now.

Both laymen and experts speak of rechargeable batteries, sometimes of batteries, and agree: the success of electro mobility ultimately depends on this high-tech component, which is as expensive as it is sophisticated, and above all on the cost-effectiveness, efficiency and everyday usability of the electric car.

Electric car without battery? Nothing works without lithium ions

Almost always, the battery is a lithium-ion technology. Batteries differ depending on the manufacturer of the materials used. Common to them is that they use lithium, both in the electrodes – ie anode and cathode – as the electrolyte itself.

The battery is the most varied, sometimes contradictory requirements: Cheap it should be. This helps the most likely to increase the number of units. Lithium should not be running low, at least for now. A battery should be light , but this does not correspond to its nature. For this reason, research has long ago been testing other materials , for example plastics and glass, sulfur and silicon.

Solid batteries may be several times more powerful than those with a liquid membrane. All announced new batteries charge faster , last longer and are safer. Solid state batteries, so the term for solid batteries, could be used even at low temperatures and cheaper to produce – so very close to the ideal battery.

In development: load more often, faster, cheaper

Lithium iron phosphate batteries are widely used in China today – rugged models that can handle up to 10,000 charging cycles. They are temperature stable, but with lower energy density than European or Japanese lithium-ion batteries.

Researchers are currently testing battery types that can handle up to 15,000 charge cycles without significant capacity loss. However, compromises have to be made elsewhere: in terms of energy density, charging time, weight or lifespan.

Bosch wants to double the charge capacity of its batteries by 2020, so that a range of 400 kilometers is achieved.
