2.0 Why Do Companies Migrate?
Given the critical nature of database applications in the life of a business, it is often hard to believe that a company would choose to jeopardize its operations by moving to another vendor’s database system. Indeed the fact that some business applications were written many years ago and were modified over the years by personnel who may no longer be in the company, it is understandable that there is not only trepidation about making a move to a new database system, but also there may be a high cost associated with the mechanics of the migration. But the fact is that companies vehemently oppose being trapped on one vendor’s products because there can be serious consequences such as higher total cost of ownership (TCO), less scalable solutions, a lack of developers, and more. But there are also issues about the flexibility of the business and how it can be negatively affected by the inability to move quickly because of being trapped on ...

6.0 Summary and Conclusion

The factors listed though impressive and quite thorough, lacks in three crucial factors we believe would make a deep influence in choosing a provider. They are future scalability and expandability, flexibility to adapt to probable changes during development and maturity of technology being used. Elaborating on why the above stated factors are important to be considered during the selection process, we believe that sufficient forethought and foresight needs to be put on to predict future demand and load on the software and evaluate if the provider can handle these predicted future requirements by upgrading and scaling their system. With a focus on agility, the SiL’K team needs to ensure if the providers are flexible enough to accommodate a change if one arises outside the scope of the initial requirement specification. This is more of a qualitative assessment. Lastly, the third factor stresses on evaluating the technology used in the provider’s implementation. Care must be taken to ensure though the technology can meet the current needs, it is of the modern age and has sufficient maturity to evolve over a period of time to enjoy advantages of new, upcoming enhancements.

The existing system is not an intricate mix of hardware and software and will support change. Any foreseeable concerns will arise when transitioning data, generating correct reports and customer emails, implementing proper data security measures and testing. The vendor will have a major part in providing those features and services. Financially, transitioning to a cloud-based system is best for PEP. Maintenance costs are limited as support will be given by the vendor.
In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.
