Describe the Structure of Database.
Answers
Answer:
Database is a term to refer to a collection of records which could be anything such as inventory data, user's data etc. Now, how do we store it on a computer is another technical issue. I can use linked list, array, tree, graph etc. to store my records depending on the usecase. Thus, data structure is a technical term given to these structures. In short, database is more of business term or folklore term and data structure is a technical term to refer to the collection of records.
Explanation:
The database structure is the collection of record type and field type definitions that comprise your database:
Record Types. These define the type of entities or research objects you wish to capture (e.g. Person).
Fields. These are the properties or attributes that describe your record types (e.g. Gender, Age, Height etc.).
Collectively, these define the information or data that can be stored in any record of that type. Changing database definitions does not invalidate existing data. In this way, the database can grow as your research progresses.
When you create a new standard database, a ‘starter’ base set of commonly used predefined record types (e.g. Web Page, Person, Organisation, Digital Media etc.) and field types (Author, Given Names, Chapter Title etc.) are copied to the new database.
You can choose to use the predefined record and field type definitions as is or modify them, or create new ones as you wish. You can also import additional record and field types required for more specialised data.
The record types defined in the database are grouped under tabs across the top of the page. These tabs are simply an organisational convenience. Tabs can be reordered by dragging them, and created/deleted/renamed through the +/- tab on the right. Record types can be moved from tab to tab by selecting from the Group dropdown on each line.
Note. Field types are also organised into tabs in the same way...
