Comprehensive SQL Development Services

Custom SQL applications are software tools that are developed based on the company’s goals, business logic, and data specifics. These services allow you to interact with the database through SQL queries, implement authorization, data processing, report visualization, import, and export data from various sources, etc. They are suitable for businesses that find standard tools insufficient: they need support for complex transactions, access control, or integration with various systems.

We offer SQL development services that include the creation, testing, and scaling of such applications. A SQL Server consultant works with you to select the optimal architecture for the load of a particular system.

The SQL Server platform allows you to store, process, and analyze large amounts of structured data with high performance and reliability. Such systems are chosen by companies that value business process continuity, access control, and query execution speed: financial companies, e-commerce, manufacturing, etc. 

We provide a full cycle of SQL development: data structure modeling, procedure creation, and integration with other services. SQL Server experts work on the implementation, taking into account the performance and architecture requirements of the project.

Effective data management starts with a well-designed architecture. Therefore, database design includes concept development, defining the logical and physical structure for storing and processing data. The architecture adapts to business processes and can include a different structure: from local servers to hybrid cloud models with redundancy and automatic scaling. It determines how data is stored, transmitted, protected, and interacts with external systems.

High-quality design ensures stability, performance, and readiness of the system for business development. That’s why we create solutions for companies that need to ensure information integrity, quick access, and future scalability. We provide SQL database services, creating schemas based on business logic and expected load. You can also order SQL Server consulting for complex or hybrid architectures.

Delays in query processing, excessive server load, and slow analytics occur due to inefficient table structure, lack of indexes, or duplicate data. Optimizing the performance of a SQL-based database allows you to eliminate these bottlenecks and ensure stable system operation even under high load.

This type of service is suitable for companies that work with numerous queries or process financial transactions, orders, and reports online. Before starting the configuration, our SQL developers analyze the query execution plan, indexes, triggers, and locks. Based on the audit, we optimize the structure, improve performance, and reduce the load without losing functionality.

.

Data migration and SQL system upgrades are critical steps that require accuracy, consistency, and data protection. We use indexed migration, version control, backups, and schema validation. Updates are performed in stages with performance, integrity, and compatibility testing.

This is necessary for companies that are moving to new versions, changing infrastructure, or integrating multiple sources into one system. As a SQL Server consulting company, we ensure secure data transfer, integrity checks, schema adaptation, and guarantee minimal downtime.

Our team assists companies that store personal data: financial, medical, legal, customer, or personnel. Access violations, data loss, and lack of control are critical risks for businesses that work with a large amount of internal or confidential information.

That’s why we implement access, audit, and encryption systems in accordance with security requirements. Get SQL Server consulting services to customize your infrastructure to meet industry requirements and conduct a full risk assessment.

Companies that work with large amounts of data need efficient tools for analysis and reporting. This allows you to make more informed decisions, such as cost optimization, sales forecasting, inventory management, choice of promotion channels, and production planning. If you require a SQL programmer, leave a request. Our experts will help you implement a full cycle of data processing — from data collection and transformation to visualization and automatic reporting.

Our SQL Development Approach

We create a system based on the real needs of the business: from stability to flexibility and security. We are consistent and transparent at every stage of the process.

Discovery and Planning

Before starting development, we study business objectives, analyze the amount and sources of data. We formulate a technical task for SQL Server database development, taking into account future workloads and system integrations.

Design and Prototyping

What exactly should the database look like, what will it contain, what are the relationships and data types? To agree on the final structure of the solution, we develop a prototype.

Development and Integration

Then we build the system according to the agreed architecture and integrate it with other services. We carry out the full cycle of SQL development — from schemas to procedures.

Quality
Assurance

To ensure that the database remains stable in any conditions, we check the correctness of queries, optimize execution plans, and test the system under real load.

Deployment and Support

At this stage, we check configurations, accesses, set up backups, and monitor the system. In this way, we guarantee the stable operation of the SQL system after launch in accordance with the agreed SLA.

FAQs

Yes. When you order SQL Server consulting, we audit the architecture, table structure, indexes, queries, and procedures. Based on the results, we offer solutions: query optimization, structure changes, replication setup, indexing, or implementation of new schemas.

The duration depends on the scale of the project and the number of integrations:

  • Simple development is approximately 2 to 4 weeks.
  • Medium complexity projects — 1–3 months.
  • Large systems with integrations and analytics — 3 months or more.

The price is formed depending on the model of cooperation (fixed budget or hourly), the scope of tasks and the selected technologies. Factors affecting the price:

  • Type of database: MS SQL, PostgreSQL, MySQL, Oracle.
  • Availability of ETL, BI, API integrations.
  • Migration, optimization, preparation for AI/ML.
  • Urgency, scope, post-launch support.

We offer flexible terms and always agree on a budget before starting work.

Yes. Our SQL-based database services include a full migration cycle:

  • structure analysis,
  • data export,
  • format transformation,
  • integrity check.

We use backups, ETL processes, scripts, and SSMS tools. Migration is performed in stages — with testing, logging, and access protection. We support migration between SQL Server versions, cloud platforms, and other DBMSs.

At the customer’s request, we implement reports, dashboards, and analytical systems. We work with Power BI, Tableau, and other tools, integrating them into existing solutions. What exactly can be integrated:

  • ERP systems: Oracle JDE, NetSuite, EBS, EPM;
  • CRM platforms: AmoCRM, ZOHO, Creatio (BPM Online), HubSpot;
  • Payments, finance, e-commerce: exchange rates, auto-payments;
  • Data sources and databases: Google Sheets, Excel, SharePoint, MS SQL Server, SSAS;
  • Digital marketing: Facebook Ads, Google Ads, Google Analytics.

Formats and complexity of visualizations are discussed at the planning stage of SQL development.

Yes. We prepare database structures adapted for further work with artificial intelligence and machine learning algorithms. As a result, AI is trained to analyze the structure, clean up duplicate records, transform values to the appropriate formats, and optimize data.
