How does Altibase compare to Oracle and other database vendors?
While Altibase provides most of the functions/features that traditional on-disk DBMSs have, it has its own unique advantage: Altibase combines an in-memory database and an on-disk database to have the speed of in-memory and the storage capacity of on-disk into a single product. In comparison to other in-memory DBMSs, Altibase does not require additional investment for on-disk databases for large volumes of data storage, resulting in lower TCO.

How does Altibase replication compare to Oracle Real Application Cluster (RAC)?
Oracle RAC and Altibase replication are similar in that they can both be used to enable high availability architectures.

How does Altibase compare to Oracle’s database buffer cache?
Occasionally, we will be asked why Altibase outperforms Oracle since Oracle uses a buffer cache to improve performance. They will say that the buffer cache resides in memory, and so it should perform equivalent to an in-memory database. This is categorically false. While it is true that the buffer cache resides in memory and dramatically improves performance, it is absolutely not identical to an in-memory database. The buffer cache typically can only store a very small subset of data, unless the database size is extremely small. Anytime a client requests data that do not current exist in the buffer cache, it must fetch the data from the physical disk and load it into the buffer cache before it is read. This corresponding disk read dramatically reduces performance. In addition, this data caching is really only useful for reads. There is no real performance improvement when it comes to inserts, updates or deletes. In contrast, an in-memory database dramatically improves the total performance of the database regardless of the type of the SQL query made.

Can Altibase interoperate with Oracle’s on-disk databases?
Yes. Many of our clients employ architectures utilizing Altibase for improved performance, while simultaneously using Oracle as the primary data store. Altibase provides OraAdapter, which is essentially a database link that allows modified data in Altibase to be sent directly into an Oracle database. For use cases where replacement of all Oracle databases is not feasible, this method provides the optimal balance of performance, cost savings and implementation simplicity.

How does Altibase compare to other open source databases?
Altibase databases have clear advantages over other open-source databases which lack many features and functions required by enterprise clients. In addition, they have limited maturity in the enterprise space. A major weakness is their inability to support in real time and by real people.

How does Altibase enhance data security?
Data security can only be achieved by a holistic approach. Altibase provides strict data security covering all aspects of its product with extreme speed of in-memory database. Representative data security related features are its secure communication support, Audit SQL support and standard integration method support for 3rd party encryption solutions. Altibase also provides various additional security related features such as policy based password management, IP access control, object privileges and the list goes on.

How does Altibase prevent data loss?
Altibase provide multiple durability levels so that a user can select an optimal durability level with consideration of its business. Altibase Enhanced Durability level guarantees no data loss with abnormal DBMS shutdown while Altibase Strict Durability level recovers 100% data even with abnormal hardware shutdown including power failure.

Does Altibase support Business Intelligence (BI) solutions?
Yes, Altibase can be used for Data Marts in BI solutions for analytical purposes. Altibase is not ideal for data warehouses because the size of data warehouses often exceeds the maximum possible storage capacity of RAM today.

Can the same performance be achieved by using cache solutions?
No. Caching is a good strategy to use when specific query results need to be returned quickly. However, using this method does not give full flexibility for increasing performance amongst all data and operations.

Is it safe to use Altibase with regard to Intellectual Property?
Yes. It is completely safe to use all Altibase products as they are 100% free of any IP infringement. You are extremely well protected when using every Altibase product. Intellectual property is an increasingly important area of concern when making a software purchase. If you are selling a software solution that uses an infringing database, you may be liable for the financial consequences even if the IP infringement does not reside within your application! Many companies try to get around this by signing contracts with database companies ensuring that they are not liable for any infringements on the part of their database vendors. But the fact remains that customers should always exercise due diligence in making sure that their products are completely free of any IP infringement. In today's litigious society, the risks are far too high to ignore this facet of vendor selection.
