What is unnormalization in database?
Unnormalization in a database refers to the process of intentionally introducing redundancy into a database design to improve query performance and reduce the complexity of data retrieval. While normalization aims to minimize data redundancy and ensure data integrity by organizing data into related tables, unnormalization can lead to faster read operations by consolidating data into fewer tables. This approach may increase the risk of data anomalies and require more careful management of data consistency. It is often used in data warehousing and reporting scenarios where read performance is prioritized over write efficiency.
When data in a table becomes redundant?
Data in a table becomes redundant when the same information is stored multiple times across different rows or columns, leading to unnecessary duplication. This can occur when there is a lack of normalization in database design, where related data is not properly organized into separate tables. Redundant data can increase storage costs and complicate data management, making updates and maintenance more difficult. Eliminating redundancy typically involves restructuring the database to ensure that each piece of information is stored only once.
What does it mean to substantially increase?
To increase is to get larger, to have more of something. A substantial increase is an increase that is large enough to matter in some way.

What is check point in DBMS?
fuzzy checkpointIn a fuzzy checkpoint, the database server does not flush the modified pages in the shared-memory buffer pool to disk for certain types of operations, called fuzzy operations. When a fuzzy checkpoint completes, the pages might not be consistent with each other, because the database server does not flush all data pages to disk. A fuzzy checkpoint completes much more quickly than a full checkpoint and reduces the amount of physical logging during heavy update activity. When necessary, the database server performs a full checkpoint to ensure the physical consistency of all data on disk. Fuzzy OperationsThe following commonly used operations are fuzzy for built-in data types:InsertsUpdatesDeletesThe following operations are nonfuzzy:Inserts, updates, and deletes for rows that contain user-defined data types, smart large objects (CLOB and BLOB data types), or simple large objects (TEXT and Byte data types)Table alters and loadsOperations that create or modify indexes (B-tree, R-tree, or user-defined indexes)The database server flushes all the modified data pages for nonfuzzy operations to disk during a fuzzy checkpoint in the same way as for a full checkpoint.Important:Fuzzy checkpoints are disabled for the primary and secondary servers in a High-Availability Data Replication pair.Write-Ahead Logging and Fast RecoveryFuzzy checkpoint uses write-ahead logging for fast recovery. Write-ahead logging means that the logical-log records representing changes to fuzzy data must be on disk before the changed data replaces the previous version of the data on disk. Fast recovery begins with the oldest update not yet flushed to disk rather than with the previous checkpoint.Fuzzy checkpoints result in slightly longer roll-forward fast-recovery times. The database server occasionally performs a full checkpoint to prevent loss of old logical-log records.Fuzzy Checkpoints Improve PerformanceFuzzy checkpoints are much faster than full checkpoints and improve transaction throughput. Because the database server does not log fuzzy operations in the physical log, the physical log does not fill as quickly, and checkpoints occur less often. For example, if you are inserting and updating a lot of data, checkpoints occur less frequently and are shorter.The database server skips a full checkpoint if all data is physically consistent when the checkpoint interval expires. It skips a fuzzy checkpoint only if no pages have been dirtied since the last checkpoint.To improve transaction throughput, use the BUFFERPOOL configuration parameter to increase thelru_max_dirty and lru_max_dirty values. However, do not change the gap between the lru_max_dirty andlru_max_dirty values.

What is the meaning of SQL Mirroring?

What transaction would increase an asset account plus increase a liability account?
A transaction that would increase an asset account and a liability account is when a company purchases inventory on credit. In this case, the inventory account (an asset) increases, while accounts payable (a liability) also increases due to the obligation to pay the supplier in the future. This transaction reflects an increase in both resources owned by the company and the debts owed.

When two asset accounts are changed in a transaction there must be an increase and a decrease?
yes accounting equation is asset = liability +own's equity. the transaction is a decrease on account recceivable of asset and an increase on capital of asset. therefore, the equation is balanced.
