Characteristics of database approach

Characteristics of Database Approach The main characteristics of the database approach are defined as follows: - Data Redundancy is Minimized: Database system keeps data at one place in the database. The data is integrated into a single, logical structure. Different applications refer to the data from the centrally controlled location. The storage of the data, centrally, minimizes data redundancy. - Data Inconsistency is Reduced: Minimizing data redundancy using database system reducesdata inconsistency too. Updating of data values becomes simple and there is no disagreement in the stored values. E. students’ home addresses are stored at a single location and get updated centrally. - Data is Shared: Data sharing means sharing the same data among more than one user. Each user has access to the same data, though they may use it for different purposes. The database is designed to support shared data. Authorized users are permitted to use the data from the database. Users are provided with views of the data to facilitate its use. E. the students’ home addresses stored in the database which is shared by student profile system and library system. - Data Independence: It is the separation of data description (metadata) from the application programs that use the data. In the database approach, data descriptions are stored in a central location called the data dictionary. This property allows an organization’s data to change and evolve (within limits) without changing the applicati...

A relational database organizes data into rows and columns, which collectively form a table. Data is typically structured across multiple tables, which can be joined together via a primary key or a foreign key. These unique identifiers demonstrate the different relationships which exist between tables, and these relationships are usually illustrated through different types of For example, imagine your company maintains a database table with customer information, which contains company data at the account level. There may also be a different table, which describes all the individual transactions that align to that account. Together, these tables can provide information about the different industries that purchase a specific software product. The columns (or fields) for the customer table might be Customer ID, Company Name, Company Address, Industry etc.; the columns for a transaction table might be Transaction Date, Customer ID, Transaction Amount, Payment Method, etc. The tables can be joined together with the common Customer ID field. You can, therefore, query the table to produce valuable reports, such as a sales reports by industry or company, which can inform messaging to prospective clients. Relational databases are also typically associated with transactional databases, which execute commands, or transactions, collectively. A popular example that is used to illustrate this is a bank transfer. A defined amount is withdrawn from one account, and then it is deposited wi...

Introduction A database is a collection of data that is organized in a specific way, making it easy to access, manage, and update. The database approach is a method of designing and implementing a database that emphasizes the use of a specific set of characteristics to ensure that the data is accurate, consistent, and easily accessible. In this article, we will explore the key characteristics of the database approach and how they are used to design and implement effective databases. Data Independence One of the most important characteristics of the database approach is data independence. This refers to the ability to change the structure of the database without affecting the programs that access the data. This is achieved by separating the logical and physical aspects of the database, which allows the database administrator to make changes to the physical structure without affecting the logical structure. For example, imagine a database that stores information about employees. The logical structure of the database may include information such as employee name, employee ID, and employee salary. The physical structure of the database, on the other hand, may include information such as the location of the data on disk and the specific file format used to store the data. By separating these two aspects of the database, the database administrator can change the physical structure of the database, such as moving the data to a new disk or changing the file format, without affecti...

The database holds not only the organization’s operational data but also a description of this data. For this reason, a database is also defined as a self-describing collection of integrated records. The description of the data is known as the Data Dictionary or Meta Data (the ‘data about data’). It is the self-describing nature of a database that provides program-data independence. A database implies separation of physical storage from use of the data by an application program to achieve program/data independence. Using a database system, the user or programmer or application specialist need not know the details of how the data are stored and such details are “tra...

• • • • • • • • • • • • • • • • • • Data is of great importance to us and so is the operation of the available data. Our daily lives depend on data like the cost of food and medicines, the score of the match between our favorite teams, marks that we got in our exams, and the list goes on. Various big brands and businesses run on the basis of data. Operations on the data like searching for a Name in a list of thousands or storing this list of thousands in the most efficient manner possible are some of the most commonly used and most important operations in any kind of data. DBMS or Data Data can be stated as nothing but raw facts and figures. For example: “Apple”, “Car”, 100976453, 3.14157, etc. Are you able to come to any conclusion or derive some meaning out of these Strings and Numbers? NO !! The reason is simple, these are just random facts/strings/numbers. Yes, they do have some meaning. We know that “Apple” is a String and 100976453 is a number but these are just some random Strings and Numbers for us right now. Information When the data is processed, organized, and presented in a structured way then it is called information. Information can be very useful for various purposes. For example: the information about average score of a player in T20 format of cricket may have a huge impact on the player’s selection in the team and also how he/she might play on the day of the match. Predictions generated using the mathematical tools of statistics and probability are all ba...

Database Management System is a software or technology used to manage data from a database. Some popular databases are MySQL, Oracle, MongoDB, etc. DBMS provides many operations e.g. creating a database, Storing in the database, updating an existing database, delete from the database. DBMS is a system that enables you to store, modify and retrieve data in an organized way. It also provides security to the database. In this Database Management System tutorial you’ll learn basic to advanced topics like ER model, Relational Model, Relation Algebra, Normalization, File Organization, etc. • • DBMS practices questions : • • • • • • • • • • • Advantages of DBMS There are some following reasons to learn DBMS: • Organizing and management of data: DBMS helps in managing large amounts of data in an organized manner. It provides features like create, edit, delete, and read. • Data Security: DBMS provides Security to the data from the unauthorized person. • Improved decision-making: From stored data in the database we can generate graphs, reports, and many visualizations which helps in decision-making. • Consistency: In a traditional database model all things are manual or inconsistent, but DBMS enables to automation of the operations by queries.

Database Approach has many characteristics that make it more robust in nature. Let us discuss the main Characteristics of Database Approach. Also See: Characteristics of Database Approach 1. Manages Information A database always takes care of its information because information is always helpful for whatever work we do. It manages all the information that is required to us. Managing information by using a database, we become more deliberated user of our data. Also See: 2. Easy Operation Implementation All the operations like insert, delete, update, search etc. are carried out in a flexible and easy way. Database makes it very simple to implement these operations. A user with little knowledge can perform these operations. This characteristic of database makes it more powerful. 3. Multiple Views of Database Basically, a view is a subset of the database. A view is defined and devoted for a particular user of the system. Different users of the system may have different views of the same system. Every view contains only the data of interest to a user or a group of users. It is the responsibility of users to be aware of how and where the data of their interest is stored. 4. Data For Specific Purpose A database is designed for data of specific purpose. For example, a database of student management system is designed to maintain the record of student’s marks, fees and attendance etc. This data has a specific purpose of maintaining student record. Also See: 5. It has Users of Speci...
