What Are the Different Types of Data Models?
A data model determines the logical structure of a database. It helps you find possible design issues before implementing and deploying the database. However, there are different types of data models which are used for different things. That’s what we’ll discuss in this article.
The first step you should do when creating a new database is to model it. There are some basic principles that should be followed in this case.
Setting Database and Data Types in Vertabelo
Data types are very important for correctly storing information in database tables. In this article, we’ll demonstrate how to choose and implement the right data types for the database you’re designing in Vertabelo.
When designing a new database or adding tables to an existing database, it’s essential to choose the right data types; they’ll help you run the right queries, functions, and transformations on your data. Well-chosen database data types will also ensure queries have the best performance.
Database Sequences and How to Define Them in Vertabelo
All rows in a database need to have a unique identifier. But what if you need to have unique identifiers for all of the rows in all of your tables? We know GUIDs are problematic when indexing, so what other options are there? A database sequence might be a great option.
What Is a Database Sequence? A database sequence is a type of object created in a database that allows developers to generate unique values.
What Is a Relational Database Management System (RDBMS)?
The relational database management system is the backbone of every database. No matter what relational database you work with, you’ll be using its RDBMS to interact with its data.
What Does RDBMS Stand for? The acronym “RDBMS” stands for “relational database management system,” which is the part of the database that allows you to interact with the data.
Sometimes alternate acronyms are used, especially “DBMS” in relation to a database that is not necessarily relational.
