In this digital era, where every company is becoming a software company, the importance of databases is undeniable. The number of applications in the market is constantly growing, making it crucial to prioritize the performance of databases. A high-performing database facilitates seamless data management, ensuring an organized collection of data and enabling the efficient operation of numerous applications. Without optimal database performance, these applications that heavily rely on data availability for their functionalities, are bound to underperform and fail to achieve their full potential. Therefore, how does database housekeeping provides better data availability?
Data availability refers to an organization’s ability to provide access to data resources whenever required. It is highly dependent on database performance, as data inaccessibility can have adverse impacts on users’ experience of applications and services. Database housekeeping plays a key role in achieving optimum database performance, as it encompasses a set of practices that are vital for effective data management. These practices include:
1. Index maintenance
Indexes are critical in database performance. Lack of indexes leads to slow queries thus poor overall database performance. Housekeeping tasks enhances query performance, and ensure optimal data access through periodically analyzing and rebuilding indexes to remove fragmentation.
2. Data cleaning
Corrupted, inaccurate, obsolete and redundant fall into improper data types that can cause poor database performance. Housekeeping through data cleaning, or data cleansing involves identifying, removing or fixing these improper data. This process enables a database to work with relevant data, thereby improving outcomes and data management.
3. Backup and recovery
Data loss poses a significant challenge in operational processes, as it can result in downtime and revenue loss. Database housekeeping addresses this issue by scheduling automated backups, monitoring their completion, and periodically testing the recovery process to ensure data can be restored in case of system failures or data loss.
4. Security Auditing
Housekeeping involves conducting periodic security audits to identify vulnerabilities, review user access rights, enforce data encryption, and implement necessary security patches and updates. This is important because data has its owner and can contain sensitive and private information
5. Data Archiving
Certain data holds historical value for organizations, even though its active use may be minimal. Due to its significance, there is a need for data archiving. Database housekeeping involves identifying such data, creating appropriate data archiving strategies, and moving the data to archival storage. This process helps free up resources and improves database performance.
6. Monitoring and maintenance
Database housekeeping involves setting up alerts and notifications for critical events, monitoring database performance metrics, and performing routine system maintenance tasks. This enables constant monitoring on the database system, thus continuously maintain the performance of a database.
Overall, the volume of data is growing at a rapid rate as more and more applications emerge to meet the demands of users and consumers. Importantly, this increasing amount of data will continue to flood databases, necessitating the need for a high-performing database. Therefore, regular database housekeeping is essential. Ensuring optimal database performance requires constant efforts, making regular database housekeeping essential.
