It is considered the database manager par excellence worldwide, however it has its detractors

5.0 6 年前

製品を使ってみた感想: I have learned a lot using Oracle, it would be great if it were not so expensive, as well as being certified in it. It is important to know that a well-crafted database will work in any database manager, Oracle can not solve faults or problems in a poorly-related database

良いポイント:

- Allows the management of relational databases from very simple to large volumes of data. - Because it is relational, the PL / SQL language is used. - It is agile, consistent and robust. - It has all the functionalities that a DBA would like to have for the management, control and performance of the databases. - A well-configured cluster with Oracle is practically invincible. - Oracle is currently bringing all its products and services to the cloud, that is, based on Internet. - The graphic tools used with Oracle are intuitive and easy to use, practically They do all the work. - The tools also allow you to intone databases, improve performance, give you alerts. - Allows to make backup copies, partitions, manage users to control the security of information.

改善してほしい点:

- An Oracle license is very expensive, so it is not accessible to everyone. - Staff with knowledge in Oracle is equally expensive, information costs money! - It is difficult to access information related to the driver, its configuration and maintenance. - For DBA without experience, a configuration is complicated by the amount of details that must be consider. - If you do not have a graphical interface to work with Oracle, you should have knowledge in commands to work in consoles or terminals.

Oracle Database: the big name in relational and cloud DBMS.

5.0 昨年

製品を使ってみた感想: We developed a lot of Java-based desktop/enterprise applications with Oracle in the back-end. Customer support was amazing in addition to the vast amount of resources available online to tackle almost any issue in installation, setup, development and deployment. Way ahead of other rival products such as MS-SQL Server, MySQL, DB2.

良いポイント:

The advanced relational database management features from transaction management, SQL query optimization, concurrency control, security in design, to cloud integration to mention few make Oracle a way ahead of competition in the RDBMS cloud database market.

改善してほしい点:

Oracle is a bit expensive with a complicated licensing process. This is justified in return of the smartest DBMS algorithms available but still some more flexible cloud licensing strategies would make the system much better accessible to developers and administrators.

Old and Outdated and in need of refurbishing/needs to be replaced by some new Google product

2.0 5 年前

製品を使ってみた感想: Oracle helped our business use secure filesharing, but wasn't great. We stored a lot of stuff on their database but I am overall not a fan. It was helpful to our company, but I feel like there HAS to be bigger and better and more user-friendly products out there doing a better job.

良いポイント:

Had to use it for work. It was ok for filesharing, but I feel like half the time it didn't work anyway.

改善してほしい点:

DEFINITELY needs a facelift in terms of its GUI. I thiiiink it needs to be more secure too, I feel like we had issues with security but I could be wrong. Seems old and outdated and like it should have already been replaced and made obsolete by some sexy new Google or startup product.

Accurate but Expensive DB

4.0 4 か月前

製品を使ってみた感想: Overall, the Oracle DB brings the value to your organization in numerous ways. You must have some people trained very well on this DB. It's little old fashioned but brings the best of its kind, with ability to scale up and down based on your need.

良いポイント:

Accurate information collected and grouped into meaning full tables. Highly customizable database with ability to connect with other DB with APIs.

改善してほしい点:

Compared to the other DB in the market the Oracle DB is little user friendly and less sophisticated. Tools and icons in the DB itself must be remembered for fluent use. Limited analytics is available unless you want to pay more for the additional analytics and BI.

World's best RDBMS database

5.0 2 年前

製品を使ってみた感想: Since I've been an Oracle DBA for about ten years, I greatly appreciate how well Oracle Database manages the deployment of the majority of the data for the company I work for. It also enables stable backup and storage of vast volumes of data and supports a number of programming languages. Oracle offers PL/SQL, a complicated but effective query language that is not simple. The world's most potent characteristics include data auditing, backup and recovery, data encryption, as well as the capability for data analysis. Companies that use Oracle databases pay for technical support services, which are provided by highly knowledgeable and competent Oracle professionals who are available 24/7. This implies that you will never be without a solution to a problem or an issue. Cost is by far Oracle database's largest drawback.

良いポイント:

Oracle is the #1 reliable RDBMS database in the world. It is fast, reliable and secured. It is the gold standard in the database world. To scale how good is a database product, it will be placed in front of Oracle database and compare with it

改善してほしい点:

1. Oracle is not Windows operating system friendly. It is usually built on Linux, which is not user friendly for most people. Anyone who wants to become an Oracle expert will take many years to become a senior level developer or administrator2. very expensive, not for personal usage

Oracle is the best database

5.0 2 年前

製品を使ってみた感想: Overall, we just loved this product. Earlier we were on mysql, but we are not getting good performance. So we switched to oracle although cost of license goes but high but we are very satisfied . No user can complaint us about slowness or any kind of performance degradations.

良いポイント:

What i like the most about oracle is their public forum, people are very helpful and even when you log a tciket with support they are great too. Now coming to functionalities, its notification, backup strategies, IO user interface how to troubleshoot performance cases and replications stratigies were superb. I can handle everything by my own. My database size is 6TB and i can just sleep well in confidence it will work fine and perfectly

改善してほしい点:

Till now i dont have negative thing to say about oracle. Its being used my 90% of organisations and it has everything which is required by an application to make their app/website and product falwless

Oracle DBMS Versatility

5.0 2 年前

製品を使ってみた感想: Doing a base install of oracle DBMS is pretty easy. Setting up instances, tablespace, permissions, roles, and user schemas is more complex. However, having the skills necessary to do all this makes it easier. We also run Oracle RMAN for nightly backups, and transaction log backups makes our DR and recovery very easy to manage.

良いポイント:

Widely used software for the applications we need to run our business. With support options we need to ensure it remains online 100%

改善してほしい点:

Ridiculously expensive to purchase and complex license terms and conditions. Support is painful to get to the right team. however, resolution for issues once you get to the team is quick and painless.

The Best choice for Enterprises

5.0 5 年前

製品を使ってみた感想: It is the best choice if the size of data is too large and above 10 millions record of data.

良いポイント:

What I liked most about this software is selecting tree structure data by just "Connect By" keyword. It provides the most flexibility which you can consider.

改善してほしい点:

Oracle database best performance can be gained just by installing it on the Linux Distributions. If you install it on the Windows, performance will decrease and some times Listener Service will stop without any specific reason.

4.0 4 年前

製品を使ってみた感想: By using oracle database, Meterial management and costing is shown on one window.I immediate realize the product cost and price.Handling All productions Operation Due to its middleware services at one place.

The most important services is middleware, 3-4 madule can connect and generate output as per desired, For Costing point of view, We can connect Meterial Management system & inventory Management system and Billing management system to produce final costing of a product.Secondly its very easy to modify the oracle forms, reports and Formulas.Through multiple languages we can modify Oracle forms.Third its cloud services, for multi-branches organization we can avail its cloud services, from these services we can collect data form every branch at one window. We can cloud partial data for public and complete data for employees based on organization behaviour.

改善してほしい点:

Complexity is the main issue of oracle data base, Non technical user cannot use it properly.During Development Error Expectation is high due to its Senstivity of character.

I really think it's the best DBMS I've used, the dream of any database administrator

5.0 6 年前

製品を使ってみた感想: Really for me it has been very satisfactory to develop applications with this DBMS, because it has made the work more pleasant and simple, besides having the peace of mind that the database is very secure

良いポイント:

Oracle is the object-relational database engine most used worldwide. It can run on all platforms, from a PC to a supercomputer. It is a super complete DBMS, with a high degree of performance, stability and scalability, supports all the functions expected of a server is a very complete database design language (PL / SQL) that allows implementing "active" designs , with triggers and stored procedures, with a fairly powerful declarative referential integrity. It allows to implement the security of the database efficiently and effectively through the management of users, roles and passwords. It allows the use of partitions to improve efficiency, replication and even certain versions support the administration of distributed databases. The server can be run on a multitude of operating systems. The great support that the organization offers its users. It has tools that allow the database administrator to perform its function efficiently and effectively. It has tools that make the backup of the database very simple. Great capacity to restore the database and very fast recovery, in addition to having a wide type of data which facilitates the design of the database

改善してほしい点:

What I like least is that it is a bit expensive. Another problem is the need for adjustments. A common mistake is to think that it is enough to install Oracle on a server and directly plug in client applications. A misconfigured Oracle can be desperately slow. Misconfigured Oracle can be desperately slow.

Oracle is definitely one of the best implementations of RDBMS

5.0 6 年前

製品を使ってみた感想: It is our main software work platform that we commercialize. We have been using this tool for more than 15 years.

良いポイント:

Every Oracle job I have worked has had a solid proactive team that is well read on standards and best practices and has many years of experience. Oracle is definitely one of the best implementations of RDBMS. It manages memory very efficiently and can handle complex JOIN operations which easilly cripple MySQL and MsSQL. Oracle has a great Architecture, because it is very easy to organise different applications data very well. I think the best plus for me is the SQL Engine that Oracle possess, it is very advanced, making it the only database to operate a data warehouse! Running complex queries on Oracle is just easy.Other features like Materialized Views, PL/SQL e.t.c. make Oracle have value for money

改善してほしい点:

Unintuitive performance tuning tools, and finicky optimizer. SQL*Plus with a built-in tabular format output; useful for rows that span across many lines. No, Grid Control SQL Output just doesn't cut it; it's a static output of the entire table. It doesn't have the powerful SQL*Plus commands.

Industry Leading Database System

5.0 2 年前

製品を使ってみた感想: The Bank for which I am consultant has been using Oracle for ages. If you can rely in such product for supporting trillions of financing transactions everyday, you can be sure that you have selected a great deal. I am very pleased with the performance and all the capabilities that Oracle Database has bring to our platforms.

良いポイント:

With Oracle Database you can be sure you are backed up by one of the best RDBS available on the market.

Oracle Database provides flexibility of data representation and all kinds of tools that help you succeed in your platform development. Preserving data is the most important thing in every organization.

A reliable tool to store and access data

5.0 3 年前

製品を使ってみた感想: Oracle is a powerful tool which allows me to organize my data and run daily and weekly procedures in an efficient and trustworthy manner. The integration with external visualization tools such as Spotfire is a crucial component as well. I would highly recommend this product.

良いポイント:

Oracle provides an easy and powerful way to interact with data. Capabilities such as data dictionaries and indexes make it easy to optimize the performance of existing procedures, and the organization of schemas make finding and editing current stored tables and scripts intuitive. I transitioned to using Oracle from MySQL and it has been an easy transition. It also integrates seamlessly with Spotfire to enable dynamic visualizations and enables insight into business decisions.

改善してほしい点:

The permissions granted to different departments and the access for different schemas can be confusing to navigate. I know that these permissions are enabled as a safety feature, but it is still frustrating to move through the ranks in order to enable certain accesses. The software also crashes occasionally, which was frustrating. If you are working on an already overtaxed system, be aware and save your work often in case of an unexpected closeout.

Robust and reliable

4.0 3 年前

良いポイント:

Oracle is a versatile, robust and reliable database. Can be used for a variety of work loads like OLTP and OLAP. Provides options for easy installation and maintenance but can also be tweaked by advanced users.

改善してほしい点:

License management is complex. If licenses are understood properly and not managed or tracked, it may lead to legal/financial implications.

Excerpt on Oracle Database

5.0 7 年前

良いポイント:

1. Within the Oracle databases, the application can use multiple schemas. 2. Database tables are assigned to table spaces such that their extent size reflects the size of the table 3.Ability to create all functions and procedures inside Packages [No stand Alone Implementation], and those which define the interface of the package to the outside can be declared in the package header 4. By using Dynamic SQL we've replaced bulky queries by input based optimized queries. 5. Using Oracle's 'Advanced Queuing' we implemented Asynchronous calls in the database enabling us to run processes in the background, when a separate process got executed in the foreground.

改善してほしい点:

These days capabilities like Oracle are being provided by other open source DB's like Postgres etc at a very nominal cost.

DBA for Oracle Database

5.0 昨年

良いポイント:

Having worked with Oracle Database as a DBA, I was satisfied with the functionalities, speed and overall performance of the tool. The multidimensional database enabled to design dynamic reports, and easily organize the data in excel. The sw dealt with large sets of data with an ease and rarely faced any outages / limitations.

改善してほしい点:

Nothing to highlight here. If you know your database / you can easily navigate, retrieve, edit data. Excel add in also helped to share information with others on a regular / ad-hoc basis..

Oracle review

5.0 3 年前

製品を使ってみた感想: I have been using the oracle database since my carrier beginning. It was using to load the transactional data to oracle tables and making the business use cases to perform the improvements.

良いポイント:

I have been working on the data warehouse projects using the oracle as warehouse database. It is easy to understand and loading into the oracle data base. We can create temp tables and backup tables on the fly for business calculations and remove after the data load into target tables. I would recommend to use Oracle database to use for data warehouse projects.

改善してほしい点:

I feel that if we can add fast export into files Like fast export and multi load processes. We do have this process in oracle using the bulk load too.

Best RDBMS in the market

5.0 7 年前

製品を使ってみた感想: Oracle RDBMS is a very vast topic, and it has been an adventure for me to explore its features and how it can be used to simplify the business needs of my customers.

良いポイント:

The high availability features like RAC, the replication features like GoldenGate, the different reporting capabilities using views and DBA_ views, the manageability using Oracle Enterprise Manager, all these make it the most loved Database flavor among its customers. Other flavors of databases are dwarfed when compared to its functionality.

改善してほしい点:

Oracle RDBMS gives too much importance to data consistency, and can sometimes look complex when trying to solve simple recovery issues. That is one reason why some customers are afraid to use this otherwise powerful software.

High security, simple database operations, and advanced functionality

5.0 昨年

製品を使ってみた感想: The database software Oracle is incredibly effective and high-performance. The best feature of Oracle is its connection feature, which makes it easy to connect the database to a project and save data from a project in the Oracle database. It also supports a variety of various platforms.

良いポイント:

It's a fantastic database with a wealth of functionality that is optimised, and I am the one that utilised it for a few years before moving to the cloud. Because of Oracle's excellent support and ability to manage complicated IT applications, database operations are straightforward to do and data processing is quick.

改善してほしい点:

As it's not an open-source database, we will always have to pay up front when putting a small-scale application into place. I experienced no further drawbacks, therefore if at all possible, utilise this.

Enterprise level Secured RDBMS, with many constraints and features

5.0 5 年前

良いポイント:

Oracle still hold most of the market share for providing enterprise level RDBMS but there was a time when everyone was using Oracle, I learnt about database by using syntax's written in oracle. Easy to use, toad type tools will make your life easier, it will provide you easy graphical interface to write sql codes. sometimes I feel oracle put lots of constraints in their database but that is because you need to maintain a clean and organized database

改善してほしい点:

length of procedures names has a limitation, it needs to change ,sometimes i try to write descriptive name and it will not allow me
