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 in which ALL the data is stored in a single table known as?

A database in which ALL the data is stored in a single table is known as a flat-file database. This type of database lacks the relational structure found in more traditional databases that use multiple tables to store and organize data. Flat-file databases are simple but may limit the ability to efficiently query and manage data.

What is input mask as used in database?

An input mask is a pattern or template used to control the input of data into a database field. It defines the acceptable format for data entry, such as phone numbers, dates, or social security numbers. Input masks help ensure data consistency and accuracy by guiding users to input data in a specific format.

What is The query that provides the underlying information for a report is known as the?

The query that provides the underlying information for a report is known as the data source query. It is used to retrieve specific data from a database that will be included in the report. The data source query helps ensure that the report is accurately populated with the necessary information.

Why is A database is an efficient way to share information because it?

A database is an efficient way to share information because it provides a centralized and organized repository for storing data. This allows multiple users to access and update information simultaneously, ensuring data consistency and accuracy. Additionally, databases support features such as security controls, backups, and user permissions to safeguard the shared information.

Why is the attribute of bi-directional traceability considered to be so important .?

Bi-directional traceability is important because it allows for tracking changes made in requirements documentation back to their source and vice versa. This helps ensure that all changes are properly recorded and implemented, leading to better quality control and ensuring that the final product meets the intended requirements. It also provides transparency and accountability throughout the project lifecycle.

In Indexing which data fields are required in iperms?

Additional fields like author, subject, and keywords may be included for more detailed indexing and retrieval purposes.

What are the primary goals of dbms?

The primary goals of a database management system (DBMS) are to ensure data integrity, enable efficient data retrieval and manipulation, provide data security, and facilitate data consistency and concurrency control. Ultimately, the main objective is to manage and organize data in a structured and controlled manner to support the needs of users and applications.

What are properties in relation to database?

In databases, properties are attributes or characteristics of database elements such as tables, columns, or indexes. They define specific settings or configurations that determine how the database or its elements behave. Properties can be used to control various aspects of data storage, retrieval, indexing, and performance within a database system.

What globalization has to do with management information systems?
