Database structure
What objects, properties, tables, workflows, relationships do you need to include in your database? What customization options are required? You should consider every aspect of your database structure in advance in order to ensure database compliance with business needs. For example, in CentriQS Custom Database Configurator you can manage Entities, Properties, Workflows, Enums, OLAP cubes and other components of your CentriQS database.
24x7 availability
Is there a necessity to keep your database available 24 hours 7 days a week? For example, your database may be accessed by users from different time zones so it should be operational 24 hours. Also you may employ freelancers who work on weekends.
Backup and recovery
There are two types of backup – cold backup and hot backup – which impact data consistency and user access. Cold backup means you back up your database only after all users are off the database in order to ensure data consistency in the backup copy. Hot backup means that users can be logged in the database when you are making a backup.
Database size
You need to estimate the expected disk space of your database for the first several years. Database size depends on data types, indices, tables, backups, replication files. Then you can use your estimate to manage the scalability of your server’s hardware and software.
Replication
Database replication (storing your database file on multiple storage devices on one or several computers) ensures data reliability, fault-tolerance, and accessibility but involves higher setup and maintenance costs. You should estimate the costs and understand your business needs to decide if replication is needed.
User access
Who will be the users of our database? What permissions to the data will each user have? How many concurrent users does your database support? How long will the database need to be accessible (1 year, 5 years, etc.)? Consider these critical issues to manage user access to your db.
Administration and maintenance
Database support helps you retain, restore and secure information in your custom database. Meanwhile it involves higher costs relating to database design, server maintenance, hardware and system administration, patches, upgrades, etc. You should allocate enough resources to administration and maintenance to achieve the maximum useful life of your database.
