Normalizing the database schema = Process of organizing data to reduce redundancy and improve data integrity Creating indexes = Data structures that can improve the performance of database queries Partitioning the database = Process of dividing a database into smaller, more manageable parts Changing data types = Improves the performance and efficiency of database operations

Improve maintainability = Making the database schema more consistent and easier to understand Adapt to changing business requirements = Adding new tables, columns, or relationships to the database schema Improve quality and performance = Important tool for improving the quality and performance of databases Reduce database size and improve performance = Removing unused columns and tables

Database refactoring can be a complex process = It requires careful planning and execution to avoid disrupting the operation of the database Having a backup of the database is important = To ensure data integrity in case of any issues during the refactoring process Database refactoring is an important skill for database professionals = It allows them to improve the quality, performance, and scalability of databases Database refactoring is not limited to any specific type of database = It can be applied to any type of database

Normalization = Reduces redundancy and improves data integrity Indexing = Improves the performance of database queries Partitioning = Divides a database into smaller, more manageable parts Changing data types = Improves the performance and efficiency of database operations

Process = Involves making changes to the database schema to improve its structure and performance Goals = Include improving maintainability, adapting to changing business requirements, and improving quality and performance Examples = Include normalizing the database schema, creating indexes, partitioning the database, and changing data types Precautions = Include having a backup of the database and performing the refactoring process carefully to avoid disruptions

Database refactoring can be used to improve the maintainability of a database = By making the database schema more consistent and easier to understand Database refactoring can be used to adapt a database to changing business requirements = By adding new tables, columns, or relationships to the database schema Database refactoring can be a complex process = But it is an important tool for improving the quality and performance of databases Removing unused columns and tables can reduce the size of the database and improve performance = A potential benefit of database refactoring

Normalization = Organizing data to reduce redundancy and improve data integrity Indexing = Data structures that can improve the performance of database queries Partitioning = Dividing a database into smaller, more manageable parts Changing data types = Improves the performance and efficiency of database operations

Improve maintainability = Making the database schema more consistent and easier to understand Adapt to changing business requirements = Adding new tables, columns, or relationships to the database schema Improve quality and performance = Important for improving the quality and performance of databases Reduce database size and improve performance = Removing unused columns and tables

Flow.BI = A software that imitates a perfect consultant to develop a valid Raw Data Vault 2.0 model Database Refactoring = The process of making changes to a database schema without changing its semantics Over-integrated model = A model that is the result of a decision where two business keys from two different sources are considered the same, but it is incorrect Data Consistency Problems = Issues that arise when an over-integrated model is created, causing inconsistencies in the data

To improve performance = Optimizing the database schema and indexes to enhance the speed of operations To improve scalability = Making it easier to add more data and users to the database To adapt a database to changing business requirements = Modifying the database structure to meet the evolving needs of the organization To maintainability of a database = Restructuring the database to make it easier to manage and understand

The perfect consultant = The ideal data modeler that Flow.BI aims to imitate, including their mistakes Non-integrated part of the model = Provisions in the generated model to handle errors without affecting data consistency Data in the database = Remains the same during database refactoring, only the storage and organization may change Changing business requirements = One of the reasons for database refactoring

Flow.BI imitates the human data modeler, including human mistakes = Flow.BI is designed to replicate the decision-making of a human consultant, which may lead to errors The perfect consultant would accept human imperfection = Flow.BI acknowledges that it may make mistakes similar to a human The knowledge that two business keys are actually the same = A challenge that Flow.BI faces, requiring it to make decisions that can be incorrect The perfect consultant's actions under perfect conditions with no constraints = The scenario that Flow.BI is designed to simulate

Semantics = The meaning or interpretation of a database schema, which remains unchanged during database refactoring Database Schema = The structure or blueprint of a database that defines the logical and physical organization of the data Database Indexes = Data structures that improve the speed of data retrieval operations Scalability = The ability of a database to handle increasing amounts of data and users

Raw Data Vault 2.0 model = The type of model that Flow.BI aims to develop under perfect conditions Human being = The entity that the perfect consultant and Flow.BI imitate, including their potential for mistakes Data Vault = A data modeling and database design approach that puts emphasis on historical data Performance, scalability, and maintainability = Aspects of a database that can be improved through database refactoring

Decision-making = An activity that Flow.BI performs, similar to the human consultant it imitates Database Refactoring = A process that can be used to improve the performance, scalability, and maintainability of a database Creating provisions in the generated model = An action of the perfect consultant to handle the potential errors of Flow.BI Dealing with the results of errors without losing data consistency = A goal of the non-integrated part of the model

Improved performance = A benefit that can be achieved by optimizing the database schema and indexes Improved scalability = A benefit that can be achieved by making it easier to add more data and users to the database Adaptation to changing business requirements = A benefit that can be achieved by modifying the database structure Maintainability = A benefit that can be achieved by restructuring the database to make it easier to manage and understand

Imitating a perfect consultant = The main objective of Flow.BI's design Potential mistakes = A characteristic that Flow.BI shares with the human consultant it imitates Over-integrated model = A potential issue that can arise if Flow.BI makes incorrect decisions Non-integrated part of the model = A provision in the generated model to handle errors without compromising data consistency

Performance = The efficiency and speed at which a database operates Scalability = The ability of a database to handle increasing amounts of data and users without sacrificing performance Maintainability = The ease with which a database can be managed, updated, and repaired Business Requirements = The specific needs and objectives of an organization that drive changes in the database
