Why would you choose a database system instead of simply storing data in operating system files When would it make sense not to use a database system?
A database system provides structured data storage, efficient retrieval, data integrity, and concurrent access control that are not available with OS files. It is suitable when data needs to be queried, updated frequently, and maintained consistently across multiple users or applications. Using OS files might be more appropriate for storing small, non-relational datasets that do not require complex querying or transactional support.

What is a database and how do you create one?
A database is a collection of information stored on a computer. There are several database programs you can use to build your own database; one of the simpler ones is Microsoft Access (part of some versions of Microsoft Office). There are also specialized databases that have been set up for a specific purpose (for example, you might find a database program for storing information about your record collection).
What are the different types of rdbms available?
Some common types of relational database management systems (RDBMS) include MySQL, PostgreSQL, Oracle Database, SQL Server, and SQLite. Each has its own features, strengths, and target use cases. Users can choose an RDBMS based on factors such as scalability, performance, cost, and specific requirements of their applications.
What is the components of DBMS and how they relate to each other?
DBMS architecturespecifies its components (including descriptions of their functions) and their interfaces. DBMS architecture is distinct from database architecture. The following are major DBMS components:DBMS external interfaces- They are the means to communicate with the DBMS (both ways, to and from the DBMS) to perform all the operations needed for the DBMS. These can be operations on a database, or operations to operate and manage the DBMS. For example:- Direct database operations: defining data types, assigning security levels, updating data, querying the database, etc. - Operations related to DBMS operation and management: backup and restore, database recovery, security monitoring, database storage allocation and database layout configuration monitoring, performance monitoring and tuning, etc. An external interface can be either a user interface (e.g., typically for a database administrator), or an application programming interface (API) used for communication between an application program and the DBMS. Database language engines(or processors) - Most operations upon databases are performed through expression in Database languages (see above). Languages exist for data definition, data manipulation and queries (e.g., SQL), as well as for specifying various aspects of security, and more. Language expressions are fed into a DBMS through proper interfaces. A language engine processes the language expressions (by a compiler or language interpreter) to extract the intended database operations from the expression in a way that they can be executed by the DBMS.Query optimizer - Performs query optimization on every query to choose for it the most efficient query plan (a partial order (tree) of operations) to be executed to compute the query result.Database engine - Performs the received database operations on the database objects, typically at their higher-level representation.Storage engine - translates the operations to low-level operations on the storage bits. In some references the Storage engine is viewed as part of the database engine.Transactionengine - for correctness and reliability purposes most DBMS internal operations are performed encapsulated in transactions (see below). Transactions can also be specified externally to the DBMS to encapsulate a group of operations. The transaction engine tracks all the transactions and manages their execution according to the transaction rules (e.g., proper concurrency control, and proper commit or abort for each).DBMS management and operation component - Comprises many components that deal with all the DBMS management and operational aspects like performance monitoring and tuning, backup and restore, recovery from failure, security management and monitoring, database storage allocation and database storage layout monitoring, etc.Data definition subsystemhelps the user create and maintain the data dictionary and define the structure of the file in a database.Data manipulation subsystem helps the user to add, change, and delete information in a database and query it for valuable information. Software tools within the data manipulation subsystem are most often the primary interface between user and the information contained in a database. It allows the user to specify its logical information requirements.Application generation subsystem contains facilities to help users develop transaction-intensive applications. It usually requires that the user perform a detailed series of tasks to process a transaction. It facilitates easy-to-use data entry screens, programming languages, and interfaces.Data administration subsystem helps users manage the overall database environment by providing facilities for backup and recovery, security management, query optimization, concurrency control, and change management.
What would be an appropriate data type to choose for a fixed-length field designed to hold a person's name?
A string data type with a fixed length would be appropriate for storing a person's name in a fixed-length field. This ensures that all names are stored uniformly and can accommodate the longest expected name in the field.
What are the areas of information technology application?
Some areas of information technology application include software development, cybersecurity, networking, database management, and web development. These areas play crucial roles in various industries, such as healthcare, finance, education, and entertainment.
Why YOU choose database system instead of simply storing data in OS?
Operating System (OS) files do NOT hold data for your personal use. Any data in an OS file is used STRICTLY by the OS. A database system is used for storing data of any kind. A text file is not stored data, so you wouldn't use a database for THAT. But a dictionary of words used in the text file, along with their definitions, could use a database. Even pics can be stored in a database, and even a list of other files can be stored in a database. by:Mohammed Abu Lamdy
