Frequently Asked Questions
What's the difference between SQL and NoSQL databases?
SQL databases (PostgreSQL, MySQL) excel at structured data with ACID guarantees. NoSQL databases (MongoDB, Cassandra) offer flexibility for unstructured data and horizontal scaling. Our developers recommend the right approach based on your data model and access patterns.
How do you handle very large databases?
We specialize in scaling databases through indexing optimization, query rewriting, partitioning, sharding, and choosing appropriate technologies. Our developers have optimized systems handling billions of records.
Can your developers help migrate to a new database?
Absolutely. We handle data migration projects with zero downtime, including schema conversion, data transformation, and validation. We can migrate between different database types (SQL to NoSQL or vice versa).
Do you handle data warehousing and analytics?
Yes. Our team has expertise in BigQuery, Redshift, and Snowflake. We design data warehouses, build ETL pipelines, and optimize analytics queries for business intelligence.
How do you ensure data security and compliance?
We implement encryption at rest and in transit, role-based access control, audit logging, and backup strategies. We ensure compliance with GDPR, HIPAA, SOC 2, and other standards.
Can I hire a database developer for just a few weeks?
Yes. Our hourly model supports short engagements starting from two weeks. This is common for performance audits, optimization sprints, or architectural reviews.
