The choice of a database is typically determined by factors such as the specific use case, scalability requirements, data structure complexity, performance needs, budget constraints, and compatibility with existing systems. Different databases, such as relational, NoSQL, and NewSQL, offer unique features that can cater to different needs. Consulting with a database architect or analyst can help in making an informed decision based on these factors.
A "schema-on-read" database is one that allows users to define the structure of the data as they access it, rather than enforcing a predefined schema. This approach allows for flexibility in data organization and analysis, making it a popular choice for big data and analytics applications.
Data dependency in DBMS refers to the relationship between different data elements within a database. There are three main types: functional dependency (one attribute determines another), partial dependency (part of a composite key determines other attributes), and transitive dependency (dependency between non-key attributes). Understanding data dependencies is crucial for database normalization and maintaining data integrity.
The data type of a field determines the kind of data it can contain. For example, a field with a data type of "Text" can contain letters and numbers, while a field with a data type of "Number" can only contain numerical values. The data type is set when designing the database schema.
A database field format refers to the data type and structure used to define a specific field within a database table. It determines how data is stored, validated, and interpreted within that field, such as text, numbers, dates, or binary data. Common field formats include VARCHAR for variable-length text, INT for integers, and DATE for dates.
The database schema is the description of the database. It defines how the database is set up and what data it is to contain and control. This description is given to the DBMS to manage the data. The database state is an image of how the database looks at any given time. The database schema is set unless you change how the database is structured. The database state will change whenever new data is entered into the database and the database is updated.
A database is a bad application choice for editing graphics, because it does not have that capability.

That depends on your project. If your project has simple database, tables and queries then mysql would be the ideal choice. If there is complexity involved then use of mysqli or PDO is better.
A database checkpoint is where all committed transactions are written to the redo/audit logs. The database administrator determines the frequency of the checkpoints based on volume of transactions. Too frequent checkpoints affect performance. Checkpoints that are too long in between will cause a longer mean time to recovery because more logs will have to be applied.

Some of the most popular database design software suites include Microsoft Office, Microsoft Office Access, and Microsoft Works. Open Office is also a popular choice.
