(a) Shape Tool: Used to create and edit vector shapes, such as rectangles, ellipses, and polygons. It allows manipulation of nodes and curves to modify the shape.

(b) Crop Tool: Used to trim or mask an object or image to a specific shape or size. It removes or hides parts of the object outside the crop area, without affecting the original shape.

Delete character to the left: Pressing Backspace deletes the character to the left of the cursor.

Delete selection: If text is selected, pressing Backspace deletes the entire selection.

Move cursor left: If no character is selected, pressing Backspace moves the cursor one character to the left.

Delete previous character in a field: In some applications, Backspace deletes the previous character in a field, such as a web address or search bar.

Navigation: In some programs, Backspace acts as a navigation shortcut, taking you back to a previous page or level.

(a)A hierarchical database is a type of database that organizes data in a tree-like structure, with each record having a single parent record and multiple child records. This structure is similar to a file system, where directories and subdirectories are organized in a hierarchical manner.

KEY FEATURES OF HIERARCHICAL DATABASES:

(i)Data is organized in a tree-like structure
(ii)Each record has a single parent record and multiple child records
(iii)Relationships between records are represented as links between nodes
(iv)Data is stored in a series of segments, each containing a group of related records
(v)Supports fast data retrieval and efficient data storage

EXAMPLES OF HIERARCHICAL

(i)IBM’s IMS (Information Management System)
(ii) Windows Registry
(iii) XML (Extensible Markup Language) documents

(B) A network database is a type of database that organizes data as a network of interconnected records, allowing for multiple relationships between records. This model was developed to overcome the limitations of hierarchical databases.

IN A NETWORK DATABASE:

(i)Data is stored as a collection of records, called nodes or segments
(ii)Each record has multiple parents and children, forming a web-like structure
(iii)Relationships between records are represented as links or pointers
(iv)Each record can have multiple owners and multiple members.

FEATURES OF NETWORK DATABASES

(i)Multiple relationships between records
(ii)Flexible data modeling
(iii)Efficient data storage and retrieval
(iv)Support for large-scale applications
