1 Use a logical data model

A logical data model is a representation of the data entities, relationships, and attributes in your database system. It helps you design, document, and communicate your database structure and requirements. A logical data model can also help you avoid data redundancy, inconsistency, and errors. You can use various tools and methods to create a logical data model, such as entity-relationship diagrams, normalization, and data dictionaries.

Database Normalization:?Reduce redundancy by organizing data into tables, minimizing update anomalies.?Ensure data consistency by adhering to normalization principles. Indexing: Use indexes to speed up data retrieval, especially for frequently queried columns. Query Optimization & Review Execution:?Analyze and optimize query execution plans for efficiency. Use Stored Procedures:?Pre-compiled stored procedures enhance query performance. Regular Maintenance& Update Statistics:?Keep statistics up to date for the query optimizer to make informed decisions. Partitioning & Improve Manageability. Data Archiving of historical data using partitioning. Backup and Recovery and Test Recovery are the procedures to be carried out regularly.

One thing to consider after normalisation is whether your primary keys (that will be used as foreign keys) are char (or a variation of char) fields. Sometimes, you need to fix these for some reason (eg. maybe the format of the data needs to be fixed on some rows). In that situation, you have to go fix that data on every table it is referenced. Using an identifier type field as the primary key and creating a unique index on the primary key fields instead, can allow you to easily edit that value of the text fields if needed (in only one place) in future.

2 Implement backup and recovery strategies

Backup and recovery are crucial for ensuring the availability and integrity of your data. You should have a backup plan that specifies the frequency, type, and location of your backups, as well as the procedures for restoring your data in case of a failure or disaster. You should also test your backups regularly and monitor their status. Some backup and recovery strategies you can use are full, incremental, or differential backups, point-in-time recovery, and cloud-based backup services.

In the healthcare sector, a medical research institution faced a ransomware attack jeopardizing sensitive patient data. Their backup strategy, combining daily incremental backups and weekly full backups stored offsite, played a pivotal role. With the attack thwarted, the IT team swiftly restored the system using the latest clean backup, minimizing data compromise. Regularly practiced recovery drills and monitoring systems ensured the integrity of backups

3 Optimize your queries and indexes

Queries and indexes are the main components of your database system that affect its performance. Queries are the instructions that you use to retrieve or manipulate data from your database. Indexes are the structures that you create to speed up the search and retrieval of data. You should optimize your queries and indexes to reduce the response time, resource consumption, and network traffic of your database system. Some ways to optimize your queries and indexes are using proper data types, filtering and sorting criteria, joins and subqueries, and query plans and execution statistics.

4 Monitor and tune your database system

Monitoring and tuning your database system are the processes of collecting, analyzing, and adjusting various metrics and parameters that affect its performance and health. Monitoring helps you identify and diagnose any issues or bottlenecks in your database system, such as memory usage, CPU load, disk space, locks, and errors. Tuning helps you improve and maintain the performance and efficiency of your database system, such as by adjusting the configuration settings, cache size, buffer pool, and fragmentation.

5 Migrate to a cloud-based database service

A cloud-based database service is a type of database system that is hosted, managed, and accessed over the internet by a third-party provider. It offers several benefits for managing your complex database system more efficiently, such as scalability, elasticity, availability, security, and cost-effectiveness. You can choose from different types of cloud-based database services, such as relational, non-relational, or hybrid databases, depending on your data needs and preferences. You can also use various tools and methods to migrate your existing database system to a cloud-based database service, such as data export/import, replication, or synchronization.
