Difference between Sybase and Sybase IQ?
There are two answers to this. Sybase, or Sybase Incorporated, is a company that makes software products for enterprise systems. The company has two subsidiaries, iAnywhere and Sybase 365, both of which focus on mobility solutions. So when you say "Sybase", you are actually talking about a company. A lot of people use the term "Sybase" to describe Sybase Adaptive Server Enterprise, or Sybase ASE. This is similar to saying "Oracle", when you mean "Oracle 10g". ASE is the large scale enterprise database, and competes directly with Oracle 10g and IBM DB2. It is a row based storage RDBMS, suitable for On Line Transaction Processing (OLTP) as well as data storage and reporting. Sybase has three other database products: Sybase IQ, SQL Anywhere, and Advantage. Each is designed for a specific market. Sybase IQ is an RDBMS which uses a column-based storage system. This means it stores data based the column the data comes from, and not the row the data is associated with. Column based storage has become a very popular design over the last few years, because it is very efficient at producing reports and can hold a lot of archival data in a much smaller footprint. Sybase IQ has been around for over 10 years, and is about to hit release 15.0 (sometime in the first half of 2009). This is signifcantly longer than some of it's competitors, who have only just started building column oriented storage systems. For this reason it is very popular for most reporting applications, incuding data warehouses and datamarts. Sybase IQ uses the same SQL syntax as Sybase ASE, and is fully ANSI SQL compliant. It stores data in tables, the same way as other relational databases. Any application or reporting engine that can run queries against Sybase ASE (or any relational database, for the most part) can use Syabse IQ. The only difference is "under the hood" in the disk storage mechanism.
What advantages are there to using parametric equations instead of numeric values?
Frequently you have to solve complex sets of equations with many variables of different units. It is impractical to use numeric values because it makes the solving process obscure and therefore prone to bugs. It is easier to solve parametric equations down to the point where you have a relatively simple equation and then put in numeric values with their respective units. Plus, you can reuse the parametric equations easily and track how did you solve them any time later.
How much does a computer engineer make per hour?
Depends on where you live and what school you went to. It also depends on your specific specialty. Are you designing computer architecture, or are you a software engineer? A software engineer for VM Works in Palo Alto makes between $130-160K a year. Not bad for a 32 year old.
Two principal integrity rules for the relational model?
Integrity Rules Although integrity rules are not part of normal forms, they are definitely part of the database design process. Integrity rules are broken into two categories. They include overall integrity rules and database-specific integrity rules. == The two types of overall integrity rules are referential integrity rules and entity integrity rules. Referential integrity rules dictate that a database does not contain orphan foreign key values. This means thatEntity integrity dictates that the primary key value cannot be Null. This rule applies not only to single-column primary keys, but also to multi-column primary keys. In fact, in a multi-column primary key, no field in the primary key can be Null. This makes sense because, if any part of the primary key can be Null, the primary key can no longer act as a unique identifier for the row. Fortunately, the Access Database Engine (Access 2007's new version of the JET database engine, available with the new ACCDB file format) does not allow a field in a primary key to be Null.Database-Specific Rules The other set of rules applied to a database are not applicable to all databases but are, instead, dictated by business rules that apply to a specific application. Database-specific rules are as important as overall integrity rules. They ensure that only valid data is entered into a database. An example of a database-specific integrity rule is that the delivery date for an order must fall after the order date.
What is the use of databases in application software?
The application makes the database itself more intuitively user-friendly.
What does database monitoring software do?
Database monitoring software should monitor your software. It should also process the health of your pc and issue alerts for any issues that should arise.Database monitoring software makes sure important information on hard drives does not get accidentally deleted. It often also password protects data.
Why vb is known as the front-end tool?
VB is basically a programming language. For keeping records, generally we use a database like Oracle, MS ACCESS, etc. dedicatedly to store data. These databases are not good enough to code a program to develop software. Hence we need to develop software where VB is used for the programming part and database is used for the data storage part. Thus VB makes a bridge between user and database. The database cannot be directly accessed by the user but through VB. Hence the database is the back-end tool and VB is a front end-tool.
What kind of company is Nimble Storage?
The nimble storage company makes software and hardware that is required for data storage and is mainly use for backup.The company has been growing a lot recently.
Why does data inside a database need to be organized?
Organizing data in a database allows for efficient storage, retrieval, and manipulation of information. This organization helps improve data integrity, reduces redundancy, and enhances the performance of database operations. Overall, organized data makes it easier to manage and analyze information effectively.
Who makes management software for a database?

What is consistency in DBMS?
In SQL data consistency is that whenever a transaction is performed, it sees a consistent database. During the transaction, if the database is not consistent, then there are two reasons for it, which are as follows: 1-database failure (software or hardware failure) 2-multiple accesses data consistency makes sure data integrity and vice versa. :)
What is the role of data base management in information system?
The database is in effect the storage/retrieval engine withing the Information System. Data punched in a sequence to the database can be interrogated and recalled in the form of "queries". The database makes the data retrieval more efficient and flexible allowing operators to establish quite complex reports on data needed .
What makes up a database?
A database is made up of related information in Tables and fields.
Is database hardware?
A database manager is a computer program (or programs) that manages database information. Most database programs can be purchased or obtained from many places and installed on a computer. That makes it software.If the database program is part of and supplied with the computer vendors system, than it is system software.It is possible to securely store the database program in a type of memory where its location is fixed and not changeable using normal programming methods. That would make it firmware.If the database software is implemented in the actual computer machinery and not changeable without replacing or changing computer components, it would be hardware.
What is the best software out there to create a relational database?
you can use Microsoft excel what usually comes with the computer/laptop or u can download it of the miscrsoft website or the good old fashiond way buy it in computer software shops hope this is a great help Dominic barnett If you need an online database you could try www.recs4free.com This allows you to create your own tables and users. You can upload images and documents and it's all free. Martin
