Database Development

What is database development?

Database development is a process resulting in a database being planned, developed, and maintained. It is typically accomplished through several distinct phases (or iterations) that include the analysis of the data requirements, the selection of the most appropriate database technology, a process of implementation, and the optimization of performance throughout many phases.

The company could be teeming with data; it would be created everywhere, from managing clients to developing new products and preparing the accounts. Yet in chaos, without being organized, it is useless. A gigantic pile of building blocks, without a plan, without a system.

An organized sequence goes from chaos to order – data is now usable and valuable to the company, and systems are developed and used in accordance with needs.

What are the different database models?

Differences in database systems mean different architecture, range of functions, and areas of application.

Relational databases

These are the most widely used type of database. They store data in tables, which are linked to one another by relationships. They are good for structured data, data that you can represent in a relational model.

Examples of relational database systems are MySQL and PostgreSQL.

NoSQL databases, document databases

Were designed to store and manage unstructured data. They are also known as document databases for their storage principle is based on individual files or objects. NoSQL databases are perfect to store big amounts of data that cannot be mapped in a relational model, but also for caching purposes.

Examples of NoSQL databases are MongoD, Elasticsearch, and Redis.

Blockchain: decentralized databases

Of course, they’re a new kind of database, ‘blockchain’-based – or rather, a system of data that is centralized and distributed, where transaction history can never be erased (it’s the ultimate administration and recordkeeping tool), and about which I can’t say much.

What is a DBMS (database management system)?

Tenth, with a database-management system (short for DBMS), a user stores, organizes, and uses data. A DBMS performs such tasks as

• Storage and organization of data
• Access control: Only authorized users may view and change data.
• Data security: Protection of data against unauthorized access, loss, and damage.
• Performance: Retrieve and process data quickly and efficiently.
• Maintenance: Data backup, recovery, and indexing.

How is a database created?

All use cases are treated independently from the start. The reason for this is that SQL databases can’t be used everywhere, so if you said: ‘No, I’ll use MySQL for all my applications,’ then you would already be making a mistake from the start when first designing a system.

The process should therefore consist of the following six phases:

1. Requirements analysis: What needs to be stored, who needs to access it, with what authorization? What are the anticipated future areas of use in terms of upscaling and utilization – which helps with deciding on a certain system.
2. Design: In this stage of database development, you determine the architecture of the database. This includes selecting the database management technology, determining the tables, columns, and relationships between tables.
3. Development: Development of the database and transfer of available data. Migration of a system that already has data. This includes database software installation, configuration of the database, implementation of access to data.
4. Testing: Testing for errors and performance problems. Where desirable, penetration and load tests are also performed.
5. Commissioning: The database is released for users or developers.
6. Optimization: Performance, security, and scalability are maintained and adjusted as needed during runtime.

Case studies: Web databases in use

An Instagram post, an Amazon order, an online bank transfer – all produced by different systems, but they all require a common element: data storage. But they all have to operate within different constraints.

For instance, Instagram or Facebook would use their NoSQL databases to (temporarily) store magnitudes of user- and post-data, because it would be much easier to set new functions in document-based databases.

Product information, data about individual customers and their orders, history of purchases – all this is kept in cloud databases by online stores and trading platforms like Amazon. This makes cloud databases usable scalable: during high season, stores may find themselves under much heavier load than usual, but this doesn’t affect the operation of the system.

Continuous random keys are stored in the database and each data and transaction of customers and accounts are linked with these keys, that’s why security in these containers is very important because it protects the customer’s data against those attackers.

The advantages of professional database development

Comprehensive software and customers’ requirements lead to a broad development process. What are the advantages to this?

• Quality control: Professional database developers have the knowledge and experience to develop a quality database product that is a perfect fit.
• Efficiency: Advanced professionals can shorten the time required through their routine and are capable of working at low cost.

Security: It should be the first-class citizen.
Industry-specific: He should know what his clients’ needs and have nodes to do that.
Architecture: He should take care of it because no one cares about it.

Future-proof: Build for tomorrow because, tomorrow, these requirements will be much greater. Expected results: 80 per cent less to maintain, 50 per cent less to build, 100 per cent less risky.

When companies are not discriminative of their use of database system, they end up spending more on development. This simply means that the process of database development cannot be avoided at any cost by professionals such as web development agencies as this is the most crucial step in (further) developing digital products and applications.
