need to know which factors should I have to consider while Database Design.
Please help. I am new to Database Design.

  • Student Information System

    Hello,
    I am wondering if i would be able to use sharepoint as a student information system or if theres away i can use my access student information system for access with sharepoint?

    it is depend what type of information you want to store in it.You can use the OOTB feature to achieve it.
    you can use BCS and connect it to your database, in this case SharePoint will be front end.
    you can also take the advantage of the Access Web App.
    There are many school / colleges using the SharePoint. here are few ideas
    http://www.ucisa.ac.uk/groups/cisg/sharepoint.aspx
    Connect teachers, students, and parents with SharePoint Server 2007

  • Mobile information system

    Hi everyone!!
    I have been given a task to investigate and come up with an integrated all-in-one mobile student information system where students do the following:
    Students should be informed of:
    class changes by text
    inform lecturers that they will be absent
    Would be informed of upcoming seminars
    Also display a map of where they are on campus
    Provide them with information about rooms and buildings as they pass!so some kind of GPS
    for all the above issues!, what software should I be thinking of? what hardware? what technologies etc?
    what would the architecture of the potential solution be?
    Regards
    Shosoloza

    Hopefully this is not some kind of "student project", if it is, then just bag it now and tell the instructor that it is not doable within your budget and time constraints.
    If not, then you need to look at, in Java, J2EE. You're going to need a good deal of C along with that to make interfaces to other systems.

  • DataBase Design For Inventory Systems

    Sir I am doing my Final Year B.sc(Comp.sci), I am having my Oracle Project to do things.
    I just wan't a Detailed DataBase Design for
    Inventory Systems
    Please Could you help me in terms of DataBase Design......

    The best way to approach a database design is to write a
    specification for the application. Document what processes the help
    desk technicians will do. In the process, identify what pieces of
    information they work with. When you have the complete
    specification written, you can then begin grouping the pieces of
    information they work with together. For example, a ticket may have
    a number, status, priority and a person to whom it is assigned. The
    person to whom the ticket is assigned will have a name, phone
    number, e-mail address and a list of technical skills.
    So in this overly-simplified example, we could have a table
    that contains ticket information, a table that has information
    about technicians and a table of skills. Then ask your self
    questions like "Can one ticket be handled by more than one
    technician?" "Can one technician handle more than one ticket?" Can
    a technician have more than one skill?" In this way, you can begin
    seeing the one-to-one, one-to-many and many-to-many relationships
    that exist.

  • Database design (ERD )for Inventory Management System

    Dear All,
    I am going to develop a simple Inventory Management System software using C# .NET for my learning. After searching different forums, many people have suggested to first create a database design for the software. I want a database design, in short, an ERD
    diagram for simple Inventory Management System which shows proper entities(tables), attributes and relationship between entities.
    It would be highly helpful for me as I am newbie to C# and databases.
    Thanks,
    momersaleem

    Dear Rebecca,
    Thanks for you suggestions.
    As I am going to develop IMS for learning purposes so I think I wouldn't need to go in detail regarding Customer name and addresses. However, I am still thinking of adding country attribute in customers' table which I think will be helpful to sort out customers.
    What's the difference between a purchase and an order?  They're usually the same thing, which doesn't mean you're
    wrong, but what are you picturing here? Purchase entity will be used to keep record of purchases you made and an order entity will be used to keep record of orders that cutomers placed.
    Pricing:
    Any order system needs to manage two very distinct bits of data that are easy to confuse. The price in the Product entity is the current
    price. The price in the Order entity is the selling
    price. Not at all the same thing--current price is almost certainly going to change over time. Selling price won't.
    Does it mean that I'll change the price attribute for product to current_price and add selling_price to order table which will help to keep record of price at the time of order?
    Why did you include a quantity field in the Products table? Is it meant to represent stock on hand?
    Yes you are right. It represents stock in hand.
    Could you please recheck the entities relationships as I am not confirmed whether these are correct or not?
    Thanks,

  • IF Auto Update Statistics ENABLED in Database Design, Why we need to Update Statistics as a maintenance plan

    Hi Experts,
    IF Auto Update Statistics ENABLED in Database Design, Why we need to Update Statistics as a maintenance plan for Daily/weekly??
    Vinai Kumar Gandla

    Hi Vikki,
    Many systems rely solely on SQL Server to update statistics automatically(AUTO UPDATE STATISTICS enabled), however, based on my research, large tables, tables with uneven data distributions, tables with ever-increasing keys and tables that have significant
    changes in distribution often require manual statistics updates as the following explanation.
    1.If a table is very big, then waiting for 20% of rows to change before SQL Server automatically updates the statistics could mean that millions of rows are modified, added or removed before it happens. Depending on the workload patterns and the data,
    this could mean the optimizer is choosing a substandard execution plans long before SQL Server reaches the threshold where it invalidates statistics for a table and starts to update them automatically. In such cases, you might consider updating statistics
    manually for those tables on a defined schedule (while leaving AUTO UPDATE STATISTICS enabled so that SQL Server continues to maintain statistics for other tables).
    2.In cases where you know data distribution in a column is "skewed", it may be necessary to update statistics manually with a full sample, or create a set of filtered statistics in order to generate query plans of good quality. Remember,
    however, that sampling with FULLSCAN can be costly for larger tables, and must be done so as not to affect production performance.
    3.It is quite common to see an ascending key, such as an IDENTITY or date/time data types, used as the leading column in an index. In such cases, the statistic for the key rarely matches the actual data, unless we update the Statistic manually after
    every insert.
    So in the case above, we could perform manual statistics updates by
    creating a maintenance plan that will run the UPDATE STATISTICS command, and update statistics on a regular schedule. For more information about the process, please refer to the article:

  • SIMPLE Database Design Problem !

    Mapping is a big problem for many complex applications.
    So what happens if we put all the tables into one table called ENTITY?
    I have more than 300 attributeTypes.And there will be lots of null values in the records of that single table as every entityType uses the same table.
    Other than wasting space if I put a clustered index on my entityType coloumn in that table.What kind of performance penalties to I get?
    Definition of the table
    ENTITY
    EntityID > uniqueidentifier
    EntityType > Tells the entityTypeName
    Name >
    LastName >
    CompanyName > 300 attributeTypes
    OppurtunityPeriod >
    PS:There is also another table called RELATION that points the relations between entities.

    >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
    check the coloumn with WHERE _entityType='PERSON'
    as there is is clustered index on entityType...there
    is NO performance decrease.
    there is also a clustered index on RELATION table on
    relationType
    when we say WHERE _entityType ='PERSON' or
    WHERE relationType='CONTACTMECHANISM'.
    it scans the clustered index first.it acts like a
    table as it is physically ordered.I was thinking in terms of using several conditions in the same select, such as
    WHERE _entityType ='PERSON'
      AND LastName LIKE 'A%' In your case you have to use at least two indices, and since your clustered index comes first ...
    >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
    Have you ever thought of using constraints in your
    modell? How would you realize those?
    ...in fact we did.We have arranged the generic object
    model in an object database.The knowledge information
    is held in the object database.So your relational database is used only as a "simple" storage, everything has go through your object database.
    But the data schema is held in the RDBMS with code
    generation that creates a schema to hold data.If you think that this approach makes sense, why not.
    But in able to have a efficent mapping and a good
    performance we have thought about building only one
    table.The problem is we know we are losing some space
    but the thing is harddisk is much cheaper than RAM
    and CPU.So our trade off concerated on the storage
    cost.But I still wonder if there is a point that I
    have missed in terms performance?Just test your approach by using sufficiently data - only you know how many records you have to store in your modell.
    PS: it is not wise effective using generic object
    models also in object databases as CPU cost is a lot
    when u are holding the data.I don't know if I'd have taken your approach - using two database systems to hold data and business logic.
    PS2: RDBMS is a value based system where object
    databases are identity based.we are trying to be in
    the gray area of both worlds.Like I wrote: if your approach works and scales to the required size, why not? I would assume that you did a load test with your approach.
    What I would question though is that your discussing a "SIMPLE Database Design" problem. I don't see anything simple in your approach when it comes to implementation.

  • Why sql sever database design is used for essbas?

    Hi
    I am new to the Hyperion technology . i would like to know why do we use any RDBM like sql sever database design for essbase which is itself is the database.What is the main difference between these two databases?
    My understanding is that Essbase act as same as SSAS for cube and dimension building.And they use database design for storing the tables and other information.
    Thanks

    A relational database can be used for a number of reasons with Essbase (and is required in some instances). These include
    1. a repository for system tables for Shared services, EAS, Studio,EPMA, Workspace, Financial Management etc
    2. A data source for loading Essbase
    3. A work area for transformations

    Assume that the database design for College Management System. It might have enrollment module, result module, staff module, etc., including more schema objects. I'm expecting the procedures or steps involving in such designs & how to design.
    It starts with interviewing the end-user and determining their requirements .. especially flushing out all the entities (student, staff member, department, course, class, etc, etc, etc) and their attributes, then determining the relationship between said entities and attributes.  Those entities, attributes, and relationships will be your logical database design.

  • Flex Student Information Management Portal help

    I am building a student information management portal in flex /php (using AMFPHP), but being a Flex Newbie, I have been researching endless on the internet for help to kick start my project. My project will be interfacing with an oracle database system (which is not an issue, I have already built connection classes in php in my past projects). My problem is binding the data. It appears in my opinion that the data grid is the only way to output the data which will not work efficiently in my case. I need a fluid and flexible layout to present the data within the page. Can the query results be binded say in labels etc and if so, how can this be achieved. Any pointers to tutorial sites for beginners will be greatly appreciated. Thanks

    Google "Flex in a week".
    Yes, you can bind labels, but given that you are asking the question, you really have a way to go in knowing how to build a portal.

  • Database design to support parameterised interface with MS Excel

    Hi, I am a novice user of SQL Server and would like some advice on how to solve a problem I have. (I hope I have chosen the correct forum to post this question)
    I have created a SQL Server 2012 database that comprises approx 10 base tables, with a further 40+ views that either summarise the base table data in various ways, or build upon other views to create more complex data sets (upto 4 levels of view).
    I then use EXCEL to create a dashboard that has multiple pivot table data connections to the various views.
    The users can then use standard excel features - slicers etc to interrogate the various metrics.
    The underlying database holds a single days worth of information, but I would like to extend this to cover multiple days worth of data, with the excel spreadsheet having a cell that defines the date for which information is to
    be retrieved.(The underlying data tables would need to be extended to have a date field)
    I can see how the excel connection string can be modified to filter the results such that a column value matches the date field,
    but how can this date value be passed down through all the views to ensure that information from base tables is restricted for the specied date, rather than the final results set being passed back to excel - I would rather not have the server resolve the views
    for the complete data set.
    I considered parameterisation of views, but I dont believe views support parameters, I also considered stored procedures, but I dont believe that stored procedures allow result sets to be used as pseudo tables.
    What other options do I have, or have I failed to grasp the way SQL server creates its execution plans and simply having the filter at the top level will ensure the result set is minimised at the lower level? (I dont really want the time taken for the dashboard
    refresh to increase - it currently takes approx 45 seconds following SQL Server Engine Tuning Advisor recommendations)
    As an example of 3 of the views, 
    Table A has a row per system event (30,000+ per day), each event having an identity, a TYPE eg Arrival or Departure, with a time of event, and a planned time for the event (a specified identity will have a sequence of Arrival and Departure events)
    View A compares seperate rows to determine how long between the Arrival and Departure events for an identity
    View B compares seperate rows to determine how long between planned Arrival and Departure events for an identity
    View C uses View A and view B to provide the variance between actual and planned
    Excel dashboard has graphs showing information retrieved from Views A, B and C. The dashboard is only likely to need to query a single days worth of information.
    Thanks for your time.

    You are posting in the database design forum but it seems to me that you have 2 separate but highly dependent issues - neither of which is really database design related at this point.  Rather you have an user interface issue and an database programmability
    issue.  Those I cannot really address since much of that discussion requires knowledge of your users, how they interface with the database, what they use the data for, etc.  In addition, it seems that Excel is the primary interface for your users
    - so it may be that you should post your question to an excel forum.
    However, I do have some comments.  First, views based on views is generally a bad approach.  Absent the intention of indexing (i.e., materializing) the views, the db engine does nothing different for a view than it does for any ad-hoc query. 
    Unfortunately, the additional layering of logic can impede the effectiveness of the optimizer.  The more complex your views become and the deeper the layering, the greater the chance that you befuddle the optimizer. 
    I would rather not have the server resolve the views for the complete data set
    I don't understand the above statement but it scares me.  IMO, you DO want the server to do as much work as possible since it is closest to the data and has (or should have) the resources to access and manipulate the data and generate the desired
    results.  You DON'T want to move all the raw data involved in a query over the network and into the client machine's storage (memory or disk) and then attempt to compute the desired values. 
    I considered parameterisation of views, but I dont believe views support parameters, I also considered stored procedures, but I dont believe that stored procedures allow result sets to be used as pseudo tables.
    Correct on the first point, though there is such a thing as a TVF which is similar in effect.  Before you go down that path, let's address the second statement.  I don't understand that last bit about "used as pseudo tables" but that sounds more
    like an Excel issue (or maybe an assumption).  You can execute a stored procedure and use/access the resultset of this procedure in Excel, so I'm not certain what your concern is.  User simplicity perhaps? Maybe just a terminology issue?  Stored
    procedures are something I would highly encourage for a number of reasons.  Since you refer to pivoting specifically, I'll point out that sql server natively supports that function (though perhaps not in the same way/degree Excel does).   It
    is rather complex tsql - and this is one reason to advocate for stored procedures.  Separate the structure of the raw data from the user.
    (I dont really want the time taken for the dashboard refresh to increase - it currently takes approx 45 seconds following SQL Server Engine Tuning Advisor recommendations)
    DTA has its limitations.  What it doesn't do is evaluate the "model" - which is where you might have more significant issues.  Tuning your queries and indexing your tables will only go so far to compensate for a poorly designed schema (not that
    yours is - just a generalization).  I did want to point out that your refresh process involves many factors - the time to generate a resultset in the server (including plan compilation, loading the data from disk, etc.), transmitting that data over the
    network, receiving and storing the resultset in the client application, manipulating the resultset into the desired form/format), and then updating the display.  Given that, you need to know how much time is spent in each part of that process - no sense
    wasting time optimizing the smallest time consumer. 
    So now to your sample table - Table A.  First, I'll give you my opinion of a flawed approach.  Your table records separate facts about an entity as multiple rows.  Such an approach is generally a schema issue for a number of reasons. 
    It requires that you outer join in some fashion to get all the information about one thing into a single row - that is why you have a view to compare rows and generate a time interval between arrival and departure.  I'll take this a step further and assume
    that your schema/code likely has an assumption built into it - specifically that a "thing" will have no more than 2 rows and that there will only be one row with type "arrival" and one row with type "departure". Violate that assumption and things begin to
    fall apart.  If you have control over this schema, then I suggest you consider changing it.  Store all the facts about a single entity in a single row.  Given the frequency that I see this pattern, I'll guess that you
    cannot.  So let's move on.
    30 thousand rows is tiny, so your current volume is negligible.  You still need to optimize your tables based on usage, so you need to address that first.  How is the data populated currently?  Is it done once as a batch?  Is it
    done throughout the day - and in what fashion (inserts vs updates vs deletes)?  You only store one day of data - so how do you accomplish that specifically?  Do you purge all data overnight and re-populate?   What indexes
    have you defined?  Do all tables have a clustered index or are some (most?) of them heaps?   OTOH, I'm going to guess that the database is at most a minimal issue now and that most of your concerns are better addressed at the user interface
    and how it accesses your database.  Perhaps now is a good time to step back and reconsider your approach to providing information to the users.  Perhaps there is a better solution - but that requires an understanding of your users, the skillset of
    everyone involved, what you have to work with, etc.  Maybe just some advanced excel training? I can't really say and it might be a better question for a different forum.   
    One last comment - "identity" has a special meaning in sql server (and most database engines I'm guessing).  So when you refer to identity, do you refer to an identity column or the logical identity (i.e., natural key) for the "thing" that Table A is
    attempting to model?

    Hi everyone. I'm running Arch Linux on a very basic configuration: it's an EeePC with a 2 Gb HDD. So, it's no surprise that i'm fighting for free space. With Google Chrome it's relatively easy, as i have a shortcut for it which invokes this: google-c
