3) State some of the products of Sybase?
Sybase has worlds leading products some of them are
* ASE
* Avantgo
* Power builder and power designer
* SQL ianywhere
* Sybase IQ
* Sybase replication server
* Sybase RTE
* Sybase data federation
* Main frame connect

4) Explain about the features of Sybase IQ?
Sybase IQ stores data base in the form of columns of data rather in rows. This storage model improves the accessibility and search criteria for the data. Performance of the search criteria improves greatly because it searches only columns rather than the rows and columns of the database. This is also environment friendly.

5) State some of the criticism about Sybase IQ?
Sybase storage systems are optimized for Dataware housing applications where data cannot be modified can be modified by searching and accessing the data.
Its column based search criteria gives high performance for search but it negates the writing capability to the data.
Performance for row based relational based databases is worse because it is very difficult for updating and modifying them.

6) Explain the structure of Adaptive server enterprise?
Structure of ASE installation hosts several databases and it comprises of one data server. Also system files occupy only one meta data. User databases are stored in the form of tables. Security and information privacy can be protected by setting permissions.

7) Explain about the Data integration suite features?
Data integration suite offers advanced development and management tools. Integration of data is very easy and efficient as you can navigate your data to a specified address without much difficulty. The five important features are ETL, Data federation, Replications, Real time events and search events.

8) Explain about Power Designer Data modeling software?
Power designer has two unique tools known as Link and Sync technologies. This technology offers Data base designers to design efficient data models through which one can offer efficient design. Also Data base designers can share resources among them which will improve the productivity and performance.

9) Explain about the mainframe connect tools from Sybase?
This connectivity tool gives access to high performance tools which connects you very fast to the main frame data sources. It gives you read and write access to databases. It also has a facility by which you can connect the main frame data to secondary data storage facilities.

10) Explain the benefits you can get from Mainframe connect?
These are the following benefits you can get from mainframe connect: -
1) Client applications can be enabled. External software's can be connected to the mainframe connect for higher performance.
2) Mainframe applications connect to external data through LAN.
3) New applications can be created which enables you to connect to external data or source of information.

11) Explanation about replication server software?
Replication server software makes you to manage multiple data platforms very easily. Some of the features which it provides are heterogeneous replication and synchronization across various applications bi directionally. It provides services from the client to server and server to client.

12)    Explain about Open switch business continuity software?

13)    Explain about Mirror Activator Disk mirroring?
This software works with storage replication systems and replicates the database to an available ASE or any database back up devices such as oracle. It increases the security of applications and also reduces the fail over time for data applications.

14)    Give the benefits of Data integration suite?
Some of the benefits which you can get from a Data integration suite are
1)   Flexibility: -This suite gives a greater flexibility to incorporate data from various sources such as web, file systems, etc and it can transfer this data to third party applications such as SQL, production systems, etc.

15)    Explain about Enterprise scalability and ROI of Data integration suite?
Enterprise scalability provides increased capacity without any new addition of hardware. It increases the capacity by increasing the availability in the enterprise data layer.
ROI: - Streamlining of application projects and reducing data management costs, data federation increases ROI. Complexity and superior decision making choices make ROI best in its class.

16)    Explain about ETL data integration software?
ETL supports data consolidation; it brings data from multiple sources and places it in a single repository. It brings scalable grid architecture for efficient management of data.

17)    Explain about Mobile enterprise application enablement?
Custom based applications for mobiles, existing applications, etc can be brought onto a mobile phone with this suite. It provides core integration, messaging, synchronization, data management of mobile phone, etc. It enables information exchange and transportability between developers and enterprise systems.
