What is physical schema?
Physical schema is the lowest form of abstraction with regards to the schema. It acts as the foundation for other types of schema to create relationships and indexes. Therefore, a physical schema usually indicates the storage allocation, which is defined in terms of GBs or TBs.
What is a snowflake schema?
Similar to a star schema, a snowflake schema is also a multi-dimension model used in data warehouses to support advanced analytics. Although both schemas organize the tables around a central fact table, the dimensional tables in the snowflake schema can further connect to sub-dimensional tables. The advantage of a snowflake schema is that less duplicate data is stored than in an equivalent star schema.
What is redundancy in database design?
Redundancies are a common sighting in database designs. The tricky part here is that these redundancies can be both good or bad depending on the use case. This is where normalization comes to the rescue. Database normalization is the process of structuring a database under a series of normal forms to reduce data redundancy. Both over-normalization and under-normalization will result in worse performance. Consequently, the decision to maintain or eliminate a redundancy is made by comparing the cost of operations that involve the redundant information and the storage needed.
Why is it important to name a database?
Appropriate naming makes database design schemas most effective. The names enable you to identify the purpose of an object and simplifies collaboration. Keep the following in mind while naming: Consistency is the key while naming.
Why are stored procedures important?
Stored procedures allow database development in an effective way for collaboration across teams and development between the database and functional programmers. These procedures give the database professionals the ability to change the characteristics of the database code without much overhead. In addition, they can also provide granular access to the system.
What is view level in a database?
It can be defined as the design of the database at the view level, which generally describes end-user interaction with database systems. At the view level, a user can interact with the system using an interface. Users are not aware of where and how data is stored.
Why not use reserved words in SQL?

What is schema in database?
The design of the database is called a schema. This tells us about the structural view of the database. It gives us an overall description of the database. A database schema defines how the data is organised using the schema diagram. A schema diagram is a diagram which contains entities and the attributes that will define that schema. A schema diagram only shows us the database design. It does not show the actual data of the database. Schema can be a single table or it can have more than one table which is related. The schema represents the relationship between these tables.
What is a view schema?
View Schema defines the design of the database at the view level of the data abstraction. It defines how an end-user will interact with the database system. There are many view schema for a database system. Each view schema defines the view of data for a particular group of people. It shows only those data to a view group in which they are interested and hides the remaining details from them.
Can a schema have more than one table?
Schema can be a single table or it can have more than one table which is related. The schema represents the relationship between these tables. Example: Let us suppose we have three tables Employee, Department and Project. So, we can represent the schema of these three tables using the schema diagram as follows.
How do schemas help people?

How can new information be classified?

Basic JSON Schema Example
Let’s look at an example of a JSON Schema for the above document type.
JSON Schema Keywords and Properties
We have different keywords that are used in the above example. The following list explains what each of these keywords mean.
How do I create a JSON schema?
You can use online JSON schema generators if you have a simple JSON document, then modify the schema as per the requirement of your project. Alternatively, you can build a JSON schema of your own from scratch by following the steps below
Base Schema
In the above example, $schema links to the resource that identifies the dialect and the valid schemas written for this dialect.
JSON Schema Properties
The schema that we have used in the above section is a basic outline. Lets build on it by adding an id field to the employee record.
Arrays of Things
The following example shows how we can create an object within an object that takes an array type data. Here, we will use a few new keywords in addition to the ones we have already used.
Describing Geographical Coordinates
Though the above example is limited to a use case, there are limitless uses of JSON schema. One of the areas where JSON schema can be used to validate and enforce consistency is with geographical coordinates. Because of the nature of the data, there is a high chance of accepting invalid or inconsistent data.
Schema: Definition and Origins
Types of Schemas
- There are many kinds of schemas that assist us in understanding the world around us, the people we interact with, and even ourselves. Types of schemas include: 1. Object schemas, which help us understand and interpret inanimate objects, including what different objects are and how they work. For example, we have a schema for what a door is and how to use it. Our door schema ma…
Modification of Schema
- As our example of the child changing their dog schema after encountering a tiger illustrates, schemas can be modified. Piaget suggested that we grow intellectually by adjusting our schemaswhen new information comes from the world around us. Schemas can be adjusted through: 1. Assimilation, the process of applying the schemas we already possess to understan…
Impact on Learning and Memory
- Schemas help us interact with the world efficiently. They help us categorize incoming information so we can learn and think more quickly. As a result, if we encounter new information that fits an existing schema, we can efficiently understand and interpret it with minimal cognitive effort. However, schemas can also impact what we pay attention to and how we interpret new informat…
How Our Schemas Get Us Into Trouble
- The study by Brewer and Trevens demonstrates that we notice and remember things that fit into our schemas but overlook and forget things that don’t. In addition, when we recall a memory that activates a certain schema, we may adjust that memory to better fit that schema. So while schemas can help us efficiently learn and understand new information, at times they may also d…

Logical Schema Or Conceptual Schema
- Logical Schema defines the design of the database at the conceptual level of the data abstraction. At this level, we define the entities, attributes, constraints, relationships, etc. and how their relationship would be logically implemented. The programmers and the DBA work at this level and they do all these implementations. External/Conceptual Mapping is done between the …
Physical Schema
- This is the design of the database defined at the physical level of data abstraction. This tells how the data will be stored in the storage device. The data can be stored in the form of file, indices etc. It totally depends on the database administrator(DBA) that how he wants to store the data and what are the storage structure that has to be used. It is often hidden from the programmer and t…
