Normalization is a process of reducing redundancies of data in a database. If you don't normalize you will have to repeat data entry.
Entity means a specific thing in both database work and data modeling. An entity is data that can be classified, and has a relationship with other classified data, as in entities.
An un-normalized database contains a random population of data that has not been organized into small stable data files
The mode is the most frequent number in a set of data. Frequent means the number happens most often. Eg. Data set = 2,4,7,5,9,6,3,6. the mode is 6 as it happens twice.

A data model specifies the rules and concepts on how to represent objects, their descriptions and how they relate. As such, the data model gives the definitions of the attributes and entities, specifies the datatypes of attributes and give relationships between entities.
Common errors in data modeling include: Incomplete requirements: Missing essential requirements can lead to inaccurate data models. Overlooking Relationships: Neglecting to define or represent relationships between entities and cause data inconsistencies. Normalization issues: Failing to properly normalize data can lead to insertion, update, or deletion irregularity. Lack of flexibility: Data models may struggle to remodel, to future changes or new requirements. Scalability changes: Data models should consider scalability to contain future growth.

Normalize may refer to the term in mathematical logic or theoretical computer science, it may refer to statistical technique for making two distributions identical. It may also be removing statistical errors from measured data pieces.
records, entities, fields, and databases.
Entitie are the principal data object about which information is to be collected. Entities are usually reognizable concepts,either concrete or abstract, such as: person,university,employees etc.
