Are architects rich?
Technically, at least in the US, architects are “rich.” An upper-level manager, a partner or a principal generally make more than about 95-98% of the U.S.
It’s also sort of the same way how people believe those working in the tech industry or engineering believe them to be well off..
What are the elements of data architecture?
The 5 Critical Components of a Modern Data ArchitectureFlexibility at scale. The volume, variety, and velocity of customer data is only going to increase with time. … Support for parallel and distributed processing. … Democratized data access. … Easy to use without specialized training. … Ability to handle all data types.
What are the three levels of database architecture?
DBMS – Three Level ArchitectureExternal level.Conceptual level.Internal level.
What are the 3 levels in 3 schema architecture?
This is the view of the relational database that end users see, and it involves a high level of abstraction. The second level is the logical schema or conceptual level, where designers work. The third level is the physical schema or physical level, where programmers maintain a database on a hardware system.
What are the 3 types of schema?
Schema is of three types: Physical schema, logical schema and view schema.
What is the main motive behind three level architecture?
The objectives of the three-level architecture is to separate the user’s view, It allows independent customized user views: Each user should be able to access the same data, but have a different customized view of the data.
How many schemas are in a database?

A physical database schema lays out how data is stored physically on a storage system in terms of files and indices.
Which data model is lowest level?
2 . Low level-Physical data model : provides concepts that describe the details of how data is stored in the computer model. Low level data model is only for Computer specialists not for end-user.
