Custom Database Development Services

Database Development Services.

A database can be defined as any entity (physical or electronic) that facilitates storage, modification, dissemination, and retrieval of data (raw and unprocessed facts) or information (processed data). Initially, all the services mentioned were provided physically using paper and lots of cabinets. This meant that for increased amounts of data and information, for example, large businesses and institutions, there were a lot of errors in data entry, security issues for sensitive data (police and intelligence agencies) and challenges when it came to modification and retrieval of data.

For these reasons and advancements in technology, most businesses (be it small or large organizations) have moved into electronic databases that entail electronic storage of data. This has improved data entry, storage, modification, security, retrieval, and consistency. The most popular electronic databases being used are Oracle and MySQL.

Database development can either be done and managed by the IT (Information Technology) staff in the organization or be outsourced to the numerous technology companies that are available today. Whichever method that is used, there are defined international services that are followed in order to complete the database development process. These services are database:


Most of the stakeholders and users of the database do not know much about the development of the database. All they know is that they need efficient and reliable means to store and retrieve their information. For the developers, therefore, it is crucial for them to interact with the end users of the database so that they get the requirements (business) of the database before building it.


From the perspective of the end user and the developer of the database, the requirements for the same database are different. After the developing team gathers the business requirements from the end users, they have the responsibility of translating them into database requirements. These are regarding functional and non-functional requirements that the database should be constructed upon to deliver the business requirements.


The database requirements are then used to design how the data is supposed to flow in the database once it has been completed. It defines all the users of the database and the permissions that have been given with every user interaction. The design acts as the blueprint of the database. Common tools that are used in database design include ERD (Entity Relationship Diagrams), UML (Unified Modelling Language) diagrams and flowcharts. The choice of tool to use in the design depends on the complexity of the requirements. It is also possible to use all the mentioned tools if the developers see the need to but in most cases, one or two is enough.


After the blueprint has been created then now the actual development of the database is built. This involves coding using the particularly chosen language to come up with an actual database that can store data. The development is based on the designs that were made from the database requirements that were gotten from the analyzed business requirements.


This is a stage that ensures that the database does not have any errors, syntax (errors arising from violating the rules that define development in a particular language) or logical (that it performs all the functions that it was intended to). Black box technique only inspects that data processing is efficient and proper while white box testing makes sure that not only data is, but the components involved are also functioning correctly. Testing can be unit (checking individual elements or groups), module (checking the functioning of the entire database) or integration (verifying how the database functions when it is combined with other applications).

Reporting services

This is more of acceptance testing where the database is deployed to the users (with methods like parallel, pilot and complete systems conversions) to interact with it and give recommendations on any improvements that can be made. Database documentation in this stage helps in maintenance of the database just in case of any problems or upgrading requirements.

Migration and Maintenance.

These are all the services that are carried out by the developers on the database after deployment. They can be adaptive, corrective or preventive services. Migration typically involves the addition of mechanisms that ensure data redundancy and availability at all times in operation. To get the Service check Database migration services.

An excellent database is defined by the services it offers to the data and the users. To the users, the database provides ease of use, authentication, encryption, availability and excellent performance. To the data, the database offers security, integrity, and confidentiality.
