Entities and Relationships

There are different stages in information model that can compare the basic structure for deleting information objects. This essay would also present the same taking the basic structure as the book called “The Power of the Powerless: citizens against the state in Central-Eastern Europe” and different ways of modelling the relationship between the book and other related books will be established through the examples of entities and relationships, networks and terms.

Comparing the basic structure of different models for relating information objects

Entities and relationships: In this portion of establishing the entire comparison of the basic structure of an entity and relationship with the help of the book provided can be established with the help of different examples. Here, it can be said that a library catalogue is part of a database that relates between books and subjects. Each of these books can have numerous subjects and each of the subjects can be related to many books. A library catalogue is a database that helps in searching of different items that has been specifically owned by a particular library. This library can include numerous books, journals, magazines, music scores, movies, government documents and many more. In terms of a library database it can be said that the allowance of efficiently searching for published information is specifically fulfilled provided the information found within a library catalogue. Only other and it can also be said that it works as a register that includes all the bibliographic items including a network of library situated at different locations. Library catalogue are generally present online in today’s time. Previously it was available on cards and had a physical existence, but recently it has been effectively replaced with the help of the online public access catalogue or OPAC. Library catalogue can also be represented graphically as below:

Networks: In this portion of discussion it would be discussed how citation network helps in the detection of different books and subjects. Citation network can be regarded as the science of citation that has been shaping up the social networks in terms of adding advantages relationship between authors establishing a co-authorship. It can be said that when a citation is done it relates a book in a network structure linking one book to the books that its sides for the articles are the books cited within it. Citation indexing is a much older tradition and it is first dated in between 1522 and 1524 when the index of Talmud was printed in Italy. The scientific literature has been organised in an intellectual model in terms of the disciplines and their specialities. these structures are there produced in a different manner and network in a reflexive structure with the help of involving references to the authors, establishing concepts and texting embedded within the literatures. The cognitive structure of the entire concept had been introduced in social network analysis for SNA. This gives the entire idea of how a network structure works within citation of an article and it is reproduced by the collective Ness of authors who have been organised not only by the terms of interpersonal relation but also through the codes of communication in a specific field. In this weight can be said that citation service indicators of the entire codification process.

Terms: Representing inverted index in terms of a book it can be said that at it relates to books in an unstructured text collection by identify how many books has identical terms sharing between them. Scientifically speaking, an inverted index is a term in Computer science that can be also referred as inverted files or postings files, which is first and foremost index data structure that helps in the storage of mapping taken from content. These content are usually the words and numbers that can be located within a database file or also within a document as well as a set of documents. This database files or documents or set of documents can be regarded as forward index which helps in the mapping of documents with its contents. The first and foremost purpose for the inverted index is that it allows the full text search within a document but the entire thing occurs at random and with immense speed. This increase speed of processing adds the document to the database. It can also occur the inverted file is within the database file itself instead of becoming its index.

Conclusion

In conclusion it can be said that the different ways by which a book can be related to the information system defines how entity relationships, networking in terms can be established with the help of its representation through a book and other set of books available along with it. The essay clearly states the information system with the help of references taken from these books.

Essay 2:

In this essay it would be analysed how entities and relationships for a library catalogue database works in the form of human cataloguer. It would also be discussed how the networks of the cited books could also form the influence of entitling all other books finally dealing with the full text search in the terms that has the power of enlisting different related books as per the relationship models.

Library catalogue are generally present online in today’s time. The modelling relationships can and make sure that at the book like power and powerlessness has the same elements and subjects discussed with them and it actually catches the phrases utilised with the subjects discussed. Making use of them it tallies different other books that are available in the library that has the same subject terms assigned to them. This is how the other 183 books assigned to the subject term are discovered and the human cataloguer establishes the fact that all of these books are related to the subject.

Networks: In this portion of discussion it would be discussed how citation network helps in the detection of different books and subjects. Citation network can be regarded as the science of citation that has been shaping up the social networks in terms of adding advantages relationship between authors establishing a co-authorship. The scientific literature has been organised in an intellectual model in terms of the disciplines and their specialities. these structures are there produced in a different manner and network in a reflexive structure with the help of involving references to the authors, establishing concepts and texting embedded within the literatures. The book Power of the Powerless was written as a polymeric within communist Eastern Europe. The author Havel, has written the book as not sighted any other book in this. But it is still regarded as a very influential book and once Google scholar start searching this book it gives rise to 1278 citation that are available for this book which means that some way or the other authors have related to this book written on similar subjects. It can also be noted that in some selected books the entire subject of writing the book is not related to the subject of the book in Power of the Powerless but it anyhow cites this work. Therefore it can be said that the networks of citation or the citation networks takes the terms utilised within the main link provided to the books that has been entitled having similar themes, it might also occur that these books have counter examples for argument that disagree with the content of the book taken as the main citation. Therefore it can be said that citation network also works on the information system of catching phrases and similar terms. This gives the entire idea of how a network structure works within citation of an article and it is reproduced by the collectiveness of authors who have been organised not only by the terms of interpersonal relation but also through the codes of communication in a specific field. In this regards, it can be said that citation service are the indicators of the entire codification process.

Terms: Representing inverted index in terms of a book it can be said that at it relates to books in an unstructured text collection by identify how many books has identical terms sharing between them. Scientifically speaking, an inverted index is a term in Computer science that can be also referred as inverted files or postings files, which is first and foremost index data structure that helps in the storage of mapping taken from content. The Boolean full text search is a way by which the book in question are entirely searched but they are not search accordingly and automatically with the help of sorting rules for the decrease of relevance. It searches for the words instead of the concepts like it is done in Manual natural language searching. Therefore the event where the words used within the book like ‘power’ and ‘citizens’ and ‘Eastern Europe’ are found another books as well even though they do not have any we relevant to the book is all related to the Boolean full text search. These content are usually the words and numbers that can be located within a database file or also within a document as well as a set of documents. This database files or documents or set of documents can be regarded as forward index which helps in the mapping of documents with its contents. The first and foremost purpose for the inverted index is that it allows the full text search within a document but the entire thing occurs at random and with immense speed. This increase speed of processing adds the document to the database.
