What are the drawbacks or disadvantages of the File processing approach/ file based system approach/ traditional file processing approach? Drawbacks of the file processing system approach When the file processing uses in the application software it gives extra or redundant data during execute the program. File based system stores extra data in the file system. It wastes the space of the storage disk when execute the output result. It does not support the many views for their same data in the file system data. One file approach uses for only one particular application software to uses and execute the data from the file approach. It cannot be integrated for multiple application software.

What are the components of data model in [DBMS] Relational Database Management System? There are five main components of data model in RDBMS Fields Fields are the attributed of the records. It is also called tuple of the attributes and properties or features. Fields shows the characteristics of the object such as name, age, gender, address etc. It contains also primary attribute or auto number id. Records Records are tuple or rows in the database. It shows all the data of the object inserted in the rows. It is also collection of the attributes, properties or fields. Files Files are the collections of the records. It shows the related records in the file data. It is also collections and combinations of the tuples and attributes. Databases The database is the collection of related files. It is also a group of files which is making relation to each other. Key field Key fields also called key attribute in the database of relation. There are some key at

Which characteristic of the record is too important and necessary to apply in the [RDBMS] Relational Database Management System? Main characteristic of the record in the Relational Database In the Record of the Relation database there are so many characteristics or properties and attribute to shows uniqueness of the record but there is one attribute that identify the record is unique to shows there uniqueness. There are some points to follow below to understand the type of attribute and it work. The unique attribute of the record in the relational database is called primary key. It is also called key attribute in the database property. The primary key attribute take numerical data in their field. It also called auto number in the table database. It automatically counts the serial numbers and inserts in the field of the record. Serial key attribute is the best way to find the record easily in the RDBMS. The primary key is also important role in the Relational database because when

Discuss the faster query processing method in the Distributed Database Management System model? Faster query processing method in distributed database model In the distributed database model you can apply so many queries to make faster data processing. In this model queries can be divided into sub-queries. The sub queries can execute the program of the database application in the parallel way. The sub queries can be executed the data in the database in the parallel by several sites interfaces. Thus the distributed database model can faster database processing and execute the database applications.

What do you understand by the control on the Distributed Database Management System? Control on the Distributed Database Management System It is another advantage of the Distributed Database Management System. It is distributed type of database which is control system and their owner of computer system. The local admin control the database which is divided between so many local administrators. Some administrators are control order of database which is send by the customers through the site interfaces. Some administrators are controls the database of the order processing in their computer system. Some administrators are controls the database of account holder data or information to process the money transection which is paid by the customer through the site interface of the account section for the customer. Some administrators are controls the database of sales department to process the order to the customer which the chosen earlier time through the interface of the product site.

What are the advantages of the distributed database management system database model or data model? Advantages of the distributed DBMS data model or database model In the distributed data model the data can share in the computers. One data can share one computer to another computer. The shared data between the computers you can manipulate the data for data processing work. If the attackers attacks one computer system and the system will damaged then your shareable data can help to recover the system also you can use the data for working purpose. Distributed data transfers to the computer using cryptography method if the computer systems are connect with wireless technology. The cryptography methods are more secured to exchange the data among computers because the art of this language is program with special characters. Some important data you can divide into parts which you have to store and share in the different databases, this method safest to the database security. ------------

What are the disadvantages or drawbacks in the Distributed Database Management System? Drawbacks or disadvantages of the Distributed Database Management System The distributed database is very costly to manage the data or information from different servers which is connected the database of the sites. It is difficult to develop the database application for software packages. If there are four sites of database application involve in a software packages to their development, one database application of site will damage from any issue then the database will be lose. In the distributed database there are so many bugs when processing the database for database applications. In the algorithm of database processing have so many error for executing the database program. If the user does not share the distributed database to the other connected server then the will be lost once the currently used server damage by physically harmed from other events.

What are the hierarchical characters in the data model of the hierarchical database management system [Hierarchical DBMS]? Hierarchical characters in data model of hierarchical DBMS The hierarchical characters are these characters which are inherited characters or word. It follows the rule of inheritance property. It makes a relation from parent to child. These characters also have their properties or attribute which is connected to the parent entity in data model of the hierarchical DBMS. Hierarchical characters have some characteristics of the parent and child word presented in the entity both parent and child entity. Hierarchical characters are the words that come from real world object and make real world entity in the database model hierarchical. Without hierarchical characters you cannot be create the hierarchical database model. If the hierarchical character of parent entity can be creates their child entity characters then it is possible to create the hierarchical database

What is the role of the data model in database management system [DBMS]? Role of the data model in DBMS Data model is structure in a graphical form to represent the database look like in their structure. Data model represents the organization structure in a graphical form where the database has so many relationships of the entity. Entity is a group of data, where the data is in a relation to another data. Entity is also called group of information, where the information is meaningful sentence in a description or character type data. The component of entity such as name, gender, address etc. are called attributes of the entity. You can connect the entity to entity with their properties if the properties of both entities are matched to each other. The image reference shows you the sales manager is connected to the sales employee with their property of the Sales Department. There are three entities in the structure or model of the database are Sales Manager and Sale employee are their

What are the disadvantages or drawbacks of the Relational Database Management and System? Disadvantages or drawbacks of the Relational Database Management and System If the key attributes of the relational database are fewer quantity, so there is big disadvantage of the relational database to find single or a particular record. Without any primary key attribute in the relational database it is very to find out the unique record from the table or relational database. Without any primary key attribute the record you cannot be update. You cannot be inserting the data without key attribute. You cannot be deleting the data without using key attribute. It is not possible manipulate the record without any key attribute or their record’s attribute. Without user identity and password of the relational database you cannot access the database application. If you applying granted permission on the primary database in the database application first you have to revoke the permission which has gr

What are the advantages of Relational database management system [RDBMS]? Advantages of the Relational Database Management and System Relational database can be used with one computer or more system. In this database you can find the record easily with their unique identity. Relational database can be related to other relational database with their property or attribute from the record. The relational database is easy to use for application development. The relational database enables to use the computer for search, insert, delete and update etc. The relational database can holds all the attributes of the record. This database can controlled by the query language called structured query language [SQL]. In this database the optimization of the record is very fast and easy to search that enable by the SQL programing. It is useful for represents the real life record and attributes easily. -------------------------------------------------------------------------------------------------

What are the drawbacks or disadvantages of the network database management system model? Drawbacks or disadvantages of the network database model The network database model is very complex in their structure. It is difficult to understand where the entity is connected to the other entity. When creating this model the connection line of the entities are high amount which is draw too difficult in the pictorial representation. It creates so many confusion of an entity about their multiple parent connection in the structure because of their property of 1to many and many to many connections. It inserts data according to pointer only. It updates data according to pointer only. It deletes data according to pointer only. The whole data are very complex to understand if you delete any parent entity which has many parents entity has connected will lose to accessing the data in the relations. -----------------------------------------------------------------------------------------------------

What are the advantages of the network database management system? Advantages of network data model Network database model is very flexible database according to their entity because these entities create relation to each other. In this model entity can be relate 1 to many relationships and makes fast and good accessing to database. In this model there are multiple parents in the structure of tree network model. The consistency of the model is in very huge amount of relation and accessing the database to database connection. In the model the searching of any data can easily to search from the network database model. It is used only for higher traffic comes from the users. The image shows the flexibility  of database according to admin and user interface of the database application. It can hold both the interfaces such as admin and users database.

What are the disadvantages or drawbacks of the hierarchical database model? The hierarchical model cannot represent all the relational connectivity of the entity and their attributes of the database model. It can represent only basic detail of the database model which is not proper database model. When we using this model for the project demonstration it will so lengthy to make their chart of hierarchical model and covers so much space in the board, page of the document. This model is not possible to create without hierarchical characters. When you deleted parent entity this model is does not exist for their parent base. In this model if you delete any child entity so under the deleted child entity we lose those entity which has connected to deleted child entity. In this image shows the wrong way to connect the child entity on hierarchical model which makes drawback or disadvantage of the model. If you create and connect the new entity to parent entity it makes massive structure and

What are the advantages of hierarchical database models? Advantages of hierarchical model Hierarchical database model is a simple model to represent the database connectivity of entity to entity. This model creates in the one direction which is straightforward top to bottom that makes it so simple. It is a natural database model to represent very fast and easily. It is basic understanding that the model which has the project base is the top of the head known as parent. In this model the parent represent the base of the project entity and the child represents the sub entity of the project and gives the basic details of the project. It represents the usual method of tool to set the record relationships of the entity. The hierarchical database model is very useful for hierarchical characters when we have some hierarchical character data to represent the connection of their characters with the basic entity using parent, child and their connection line. --------------------------------

What are the advantages of DBMS? The data items of relation create a complexity in the processing method. The DBMS keeps tight control on the data items which is extra data items in the system processing. Database management system are enforces the users to understand the integrity of the data items in the relational database. When the user active on the database to work on, the integrity of the data and attributes are manage by the rules of query. The database can be granted for security on the database through the password and user’s Identity. Shareable databases are very useful to processing to any in the computer system. Database Management system are very useful backend processing work. Backup and recovery procedure is a great advantage of the DBMS software package. Data processing for making the application software is very fast query process work in the DBMS to provide database. ---------------------------------------------------------------------------------------------------
