Database Programming

The advantages are as follows:

The relational database model is by far the most widely used. It is easier to control, more flexible, and more intuitive than other approaches because it organizes data in tables.

The relational model can also be used with personal computers and mainframe systems.

It allows tables to be linked. This linkage is especially useful when information is needed from multiple tables.

Methods to gather information electronically include conducting online surveys, using web analytics tools to track website traffic, monitoring social media channels for mentions and feedback, and utilizing data mining techniques to extract insights from large datasets. Additionally, email campaigns and online questionnaires can also be effective ways to collect electronic information.

1. Hardware: Physical equipment that makes up the system.
2. Software: Programs and applications that run on the hardware.
3. Data: Information that is input, processed, and stored by the system.
4. People: Individuals who interact with the system, including users and IT professionals.
5. Procedures: Rules and guidelines that govern how the system is used and managed.

A record is the part of a database that holds all the information about one item or subject. It is made up of fields which store specific pieces of data about the item or subject.

The process of eliminating repetitive information within a database is called data normalization. It involves organizing data in a database to reduce redundancy and improve data integrity, making the database more efficient and easier to maintain.

A special database of cleansed data is often referred to as a data warehouse. It is a centralized repository that stores structured and processed data from different sources, making it easier for users to analyze and make informed decisions based on high-quality data.

It is a number, but is best handled as a string in databases, so that any leading zero is not lost.

A record is a documented account of information, while information refers to data that has been processed and organized in a meaningful way. Essentially, a record is a specific instance of information that has been captured and stored for future reference.

Database properties are also known as database attributes or characteristics. These properties describe the features and characteristics of the database, such as data types, constraints, relationships, and indexing among others. They are essential for defining the structure and behavior of a database system.

if all the advantages of the database i.e "3d multiple security integrity no"

this problems are their in file system

data redundancy and inconsistency

data isolation

difficulty in accessing data

multiple user

security problems

integrity problem

no data independancy

if not needed for the user as it can cast a huge amount and overheads of purchasing the database and maintaining it.

then it make a sense not to use database system.

A library would be the best object to compare to a database. Like a database, a library stores organized information (books) that can be easily accessed and retrieved by users. Additionally, both libraries and databases use classification systems to organize their content for efficient retrieval.

The logical data independence is the ability to modify a logical schema without making external view or application program change.

The physical data independence is the ability to modify a physical schema without making external view or application prrogram change.

Strategic level information systems are designed to support strategic decision-making by top-level management. They focus on long-term goals and objectives of the organization and help in aligning information technology with overall business strategy. These systems typically include executive support systems and business intelligence tools to provide insights for strategic planning and resource allocation.

Companies typically store information in a traditional way by using physical storage devices like hard drives, servers, or paper files. These storage mediums are kept within the company premises or in designated data centers. Access to such information is often restricted and controlled through physical security measures like locked cabinets or data rooms.

A field's data type specifies the kind of data it can contain, such as text, numbers, dates, or Boolean values. This helps ensure data integrity by restricting what type of data can be entered into that field, preventing errors and inconsistencies in the database. Choosing the appropriate data type for each field is important for accurately storing and organizing data.

In general, a database is a collection of related data. In more specific terms, a database is typically a collection of computer files, usually stored on disk, used to contain and manage this data. The logical structure of a database (as organized in tables, indexes, views, etc.) does not necessarily correspond directly to its physical structure (the data files, transaction log files, etc.).

A database instance is the instantiation of memory structures and processes by a database management system manages the logical and physical structures and the data organized and stored therein. An application program must connect to and interact with the database instance in order to insert, retrieve, modify, and/or delete data stored in the database.

Advantages of internal data include control over the collection process, access to proprietary information, and potential for higher accuracy. However, disadvantages may include limited quantity of data, potential bias, and lack of external validation.

In DB2, a user is an individual who is granted permissions to access and interact with the database, while a schema is a named collection of tables, views, procedures, and other database objects owned by a user. Users are associated with schemas to define their default schema for objects they create.

The two parts to data capture are the collection of data through various sources such as forms, surveys, sensors, etc., and the processing of this data to convert it into a usable format for storage and analysis.

The utility is called "WHOIS." It provides information about the registered owner of a domain name, contact information, registration and expiration dates, and more.

1. Obtain clear consent from individuals before collecting their personal data.
2. Only collect and process data that is necessary for the stated purpose.
3. Keep data accurate and up-to-date to ensure its relevance.
4. Store data securely to prevent unauthorized access or misuse.
5. Limit the retention period of data to only what is necessary for the purpose.
6. Be transparent about how data is being used and shared with individuals.
7. Respect individuals' rights to access, correct, and delete their personal data.
8. Regularly review and update data protection policies and practices to ensure compliance with regulations.

The field that uniquely identifies a record in a table is called the primary key. It ensures that each record in a table is distinct and can be easily located and referenced.

Online databases provide advantages such as quick access to a wide range of updated information, easier searchability through keywords and filters, and the ability to access information remotely from any device with internet connection. This makes research more efficient and convenient compared to using printed materials.

Not a lot really.

They are just different names for the same thing.

Some might argue that a data centre would house IT equipment that process data so would have a lot of servers. A data warehouse would be used to store data, like archived information.

To be honest most modern IT facilities do both and are generally built the same way as both storage and processing IT equipment require the same basic infrastructure.
