These systems attempt to extend Object Oriented programming languages, techniques, and tools to provide a means to support data management tasks. Object Oriented models are client centric. Object Oriented databases uses attributes containing object identifiers to find objects that are related to other objects. When designing an Object Oriented model, you must first determine which classes require persistent storage; define persistent classes; represent relationships among persistent classes; and choose appropriate data types and value restrictions for each field. Object Oriented database models approach from the opposite direction (a programming language itself) to solve the problem of handling complex data types.
It contains all the data definitions , report format and definitions of organizations which are related and system components. Database Management System- It is a commercial software system which is used to create , maintain and provide controlled access to the repository. Database - It is a collection of logically related data which is required to meet the needs of applications or users of organizations. SQL is a special purpose programming language designed for managing data held in relational database management systems(RDBMS).  1.
Inheritance is one of the most influential concepts in object-oriented programming, and have a direct impact on how to design and write your Java classes. Inheritance is a very powerful mechanism. The concept of inheritance, is that when you write a class, you just have to determine how this class is different from some other category. Inheritance will give you automatic access to the information contained in the original class. When using inheritance, and all the categories that you write, that layer of other libraries that you use, and those of the categories as well as the standard benefit, are arranged in a strict
Differentiate between database management system and information retrieval system by focusing on their functionalities. Answer Database Management System A database management system (DBMS) is the main software tools of the database management approach because it controls the creation, maintenance and use of the databases of an organization and its end users. There are several functions that a DBMS performs to ensure data integrity and consistency of data in the database. There have ten function of database management system. there are data dictionary management, data storage management, data transformation and presentation, security management, multiuser access control, backup and recovery management, data integrity management, database access languages and application programming interfaces, database communication interfaces, and transaction management.
Database Database is an information that consists of data related with structure, meaning, purpose, users and application, objectives and fulfil need requirement. Database management system also known as DBMS is a information that been collected to general purpose. Database application is an independent programmed that provide service, storage manageable, give an efficient interfaced and generate report. There is a few functions of database which is structure definition, population, reporting ad modification of structure. There is a database functionalities that perform consistency and efficiency of database.
First, OOP consist of the programming code and data are encapsulated into “an object,” unlike PP where programming code is stored in a place in the system called a “function library” maintenance can be cumbersome. (ATK Solutions, Inc., 2015, para 4) Second, OOP entails information referred to as "class", "instance", "inheritance", and "polymorphism" that empowers the object to be flexible for reuse whereas PP is not as flexible due to its dedication to an itemized task. (ATK Solutions, Inc., 2015, para 5) Two examples of OOP in today’s programming world are Java and Ruby. (Rouse, 2008) Java is intended for use in dispersed applications on business networks and on the Internet. (Rouse, 2008) Ruby is intended for use broadly in Web applications.
To connect manually to a desired database you can pass an array of values: In the database.php: $config['hostname'] = "localhost"; $config['username'] = "root"; $config['password'] = "mypassword"; $config['database'] = "mydatabase"; $config['dbdriver'] = "mysql"; $config['dbprefix'] = ""; $config['pconnect'] = FALSE; $config['db_debug'] = TRUE; $config['cache_on'] = FALSE; $config['cachedir'] = ""; $config['char_set'] = "utf8"; $config['dbcollat'] = "utf8_general_ci"; $this->load->database($config); Web based system programming A) Server Side Processing: Server side processing is undoubtedly a strong tool in website designing, giving a site with a high level of intelligence which can be quite stunning. It can be elaborated as a process of code that happens on the server when one sends a request for a specific webpage. In alternative words, once a user queries up their browser, and tries to view the webpage, the server reads through the code to ascertain if there are any changes or calculations variations required to apply and so it produces the webpage to send to the visitor who has send the query. a) .htacess: It is configuration file which include d... ... middle of paper ... ...amless development. The factor that makes CodeIgniter completely different over many such similar tools is rich set of libraries that deliver the wonderful assortment of code events and choices.
Encapsulation Encapsulation is the packing of data and functions into a single component. The features of encapsulation are supported using classes in most object-oriented programming languages. It allows selective hiding of properties and methods in an object by building an impenetrable wall to protect the code from accidental corruption. Inheritance Inheritance is an object or class is based on another object or class, using the same implementation specifying implementation to maintain the same behavior. It is a mechanism for code reuse and to allow independent extensions of the original software via public classes and interfaces.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources. The DBMS has a function that can be differentiate from the information retrieval system.
Difference between DBMS and IRS by focusing on their functionalities. A Database Management System (DBMS) is a software system that uses a standard way of classifying, retrieving, and running queries on data. The DBMS functions is to manage any incoming data, organize it, and provide ways for the data to be modified or extracted by users or other programs. Some examples of DBMS are PostgreSQL, Microsoft Access, SQL Server, FileMaker, Oracle,Clipper and FoxPro. Since there are so many database management systems are available, so it is important to ensure that they communicate with each other.
